Here is the command line for installing in silent mode:
Window Installation:
<jre>.exe [/L<language ID>] /s [ADDLOCAL=jrecore[,extra][,other_US] | ALL] [IEXPLORER=1] [NETSCAPE6=1] [MOZILLA=1] [INSTALLDIR=<drive>:\<install_path>] [REBOOT=Suppress] [JAVAUPDATE=0] [CUSTOM=1]
Windows Offline Installation:
<jre>.exe [/L<language ID>] /s /v"/qn [ADDLOCAL=jrecore[,extra][,other_US] | ALL] [IEXPLORER=1] [NETSCAPE6=1] [MOZILLA=1] [INSTALLDIR=<drive>:\<install_path>] [REBOOT=Suppress] [JAVAUPDATE=0] [CUSTOM=1]"
where
<jre>.exe
is the single executable installer for the Java
Runtime Environment (JRE); /L<language ID>
, if used, sets
the localized language for the installer (see language
IDs); ADDLOCAL
, if used, is either jrecore[,extra][,other_US]
or ALL
; IEXPLORER=1
, if used, indicates that the Plug-in
should be registered with the Internet Explorer browser; NETSCAPE6=1
,
if used, indicates that the Plug-in should be registered with Netscape 6 or
later browsers; MOZILLA=1
indicates that the Plug-in should be
registered with Mozilla 1.1 and later browsers; INSTALLDIR
, if
used, specifies the drive and path of the installation; REBOOT=Suppress
,
if used, indicates that if locked files are encountered the computer should
not be rebooted; JAVAUPDATE=0
, if used, indicates that the Java
Update feature should be disabled (the Update tab in the Java Control Panel
will not appear); and if CUSTOM=1
is used, the user will only see
the license agreement, which must be accepted, and the progress bar.
If ADDLOCAL=jrecore[,extra][,other_US]
is used,
jrecore
indicates the core of the JRE will be installed;
extra
(optional) indicates additional Fonts, Colors, and Soundbank will be installed;
other
(optional) indicates locale-specific.jar
files will be installed.
If ADDLOCAL=ALL
is used, then all the features will be installed.
If ADDLOCAL
is not used, then only the recommended features will
be installed: jrecore
will be installed; extra
will
not be installed; other
will be installed only if l10n support,
other than English, is installed.
If INSTALLDIR
is not specified, the installation will go into
C:\Program Files\java\jre1.5.0
(default location).
|
Note The command is case sensitive and there must be no spaces in the features
listed with |
Suppose the JRE installer is jre-1_5_0-bin-b99-windows-i586-12_aug_2003.exe
;
you want to install the JRE core and additional Fonts, Colors and Soundbank;
you want to register the Plug-in with Netscape 7 and Mozilla 1.3; and you want to do a Windows Installation. Then the
command would be:
jre-1_5_0-bin-b99-windows-i586-12_aug_2003.exe /s ADDLOCAL=jrecore,extra NETSCAPE=1 MOZILLA=1
Or suppose you want all features to be installed; you only want to register
the Plug-in with Internet Explorer; you want the installation on the D
drive at java\jre
; and you want to do a Windows Offline Installation. Then the command line would be:
jre-1_5_0-bin-b99-windows-i586-12_aug_2003.exe /s /v"/qn ADDLOCAL=ALL IEXPLORER=1 INSTALLDIR=D:\java\jre"
You may find it convenient to use the "start /w
" command, as that
will cause MS-DOS to wait until the install is complete. The first example would then be:
start /w jre-1_5_0-bin-b99-windows-i586-12_aug_2003.exe /s ADDLOCAL=jrecore,extra NETSCAPE=1 MOZILLA=1
This is the command line for uninstalling in silent mode for Implementation-Version
n1.n2.n3_n4n5
:
MsiExec.exe /qn /x {3248F0A8-6813-11D6-A77B-00B0D0n1n2n3n4n50}
| Notes
|
MsiExec.exe /qn /x {3248F0A8-6813-11D6-A77B-00B0D0150000}
MsiExec.exe /qn /x {3248F0A8-6813-11D6-A77B-00B0D0151020}
If you want to create a log file describing the installation/uninstallation,
append /L C:\<path>setup.log
to the install/uninstall
command. The following is an example for installation:
jre-1_5_0-bin-b99-windows-i586-12_aug_2003.exe /s /L C:\<path>setup.log
This will cause the log to be written to the setup.log
file.
The following is an example for uninstalling:
MsiExec.exe /qn /x {3248F0A8-6813-11D6-A77B-00B0D0150000} /L C:\<path>setup.log
To verify if a silent installation/uninstallation succeeded, scroll to the end of the log file.

Dalian Atkinson: PCs charged over footballer's death named
A court order protecting the identity of two police officers charged in connection with the death of Dalian Atkinson has been lifted by a judge.
The ex-Aston Villa striker, 48, died after he was restrained by police and Tasered at his father's house in Telford, Shropshire, in 2016.
West Mercia Police constable Benjamin Monk is charged with murder.
A second officer, Mary Ellen Bettley-Smith, is charged with assault causing actual bodily harm.
Judge Simon Drew QC, sitting at Birmingham Crown Court, overturned the Contempt of Court Act order, allowing the naming of the officers after submissions by media organisations.
Both officers were present at the hearing, at which their lawyers agreed that anonymity could not be justified, instead arguing that their home addresses should not be revealed in media reports.
The officers had been granted the interim order banning publication of their names last week after it was argued there were risks to their safety.
Lawyers acting for six media organisations argued that the anonymity orders were an "unjustified" and represented a serious interference with common law open justice principles.
Latest news from the West Midlands
An alternative charge of an unlawful act manslaughter has been put forward by the CPS for PC Monk.
PC Bettley-Smith has indicated that she will plead not guilty.
The 29-year-old officer and her 41-year-old colleague are both from Shropshire, but a court order prevents the media from reporting their home addresses.
Mr Atkinson, who also played for Ipswich and Sheffield Wednesday, was detained outside an address in Trench, Telford at about 01:30 on 15 August 2016.
He was taken by ambulance to the Princess Royal Hospital, where he died.
Both defendants are next expected to appear in court on 9 December for a plea and trial preparation hearing.

Kollam ,known by its former name Quilon and Coulão (in Portuguese), and Desinganadu, is an old seaport and city on the Laccadive Sea coast of the Indian state of Kerala.It is situated 66 kilometers north of the state capital Trivandrum.The city is on the banks of Ashtamudi Lake. Kollam has a strong commercial reputation since the days of the Phoenicians and Romans.Fed by the Chinese trade, it was mentioned by Ibn Battuta in the 14th century as one of the five Indian ports he had seen during the course of his twenty-four-year travels.Desinganadu's rajas exchanged embassies with Chinese rulers while there was a flourishing Chinese settlement at Kollam.
Palaruvi Falls (Malayalam: പാലരുവി വെള്ളച്ചാട്ടം) is a waterfall located in Kollam district in the Indian state of Kerala. It is the 32nd highest waterfall in India. Palaruvi (literally "stream of milk") falls from a height of 300 feet (91 m) and is situated at Aryankavu in the Kollam district of the south Indian state of Kerala.
Read MoreLocated in the Kollam district in Kerala, Thenmala is a UNESCO World Heritage Site that sits at the foothills of the Western Ghats. The region is full of unique animals and botanic life — the wet monsoon climate together with the volatile temperatures through the course of passing seasons germinates a rich and diverse ecosystem. Along with other nearby tourist destinations, Thenmala is spread across three river basins — Pamba, Achencoil and Kallada.

High level slider and wheel processing module.
Slider processing APIs apply to sliders and wheels. Sliders and wheels share sensor structures (tSlider). A wheel is identical to a slider, except its filtering algorithm allows wrap-around on the endpoints.
| uint16_t CAPT_computeArcTanApprox | ( | int32_t | i32XComp, |
| int32_t | i32YComp | ||
| ) |
Trigonometric Arctan approximation
Perform an arctan(YComp/XComp) approximation using a linear approximation with basic error correction, to give max error of +- 1 degree. A full 0 to 360 degree output range is achieved.
| i32XComp,i32YComp | are the X and Y vectors |
| uint16_t CAPT_computeSliderVectors | ( | tSensor * | pSlider | ) |
Calculate Slider Position
Slider position is calculated using a vector sum method.
| pSlider | is a pointer to the Slider Sensor to process |
| uint16_t CAPT_computeWheelWrap | ( | int16_t | i16Position, |
| uint16_t | ui16MaxPosition | ||
| ) |
Test for a wrap on slider / wheel
With the slider/wheel functionality working in a 0-360 degree vector plane, a value must always be checked if it has not wrapped, and thus must be kept between 0 and 360.
| i16Position | is the slider/wheel position to check for wrapping |
| ui16MaxPosition | is the wrapping value (relating to 360degrees) |
| void CAPT_processSlider | ( | tSensor * | pSlider | ) |
Perform processing for a Slider
Here processing is performed on a slider sensor implementation. This includes calculating the slider output position and filtering of this position.
| pSlider | is a pointer to the Slider Sensor to process |
| uint16_t CAPT_getSensorPosition | ( | tSensor * | pSensor | ) |
Get the position value for a slider or wheel sensor.
This function provides easy access to the slider or wheel position value.
| pSensor | is a pointer to the sensor to query |

A cron expression is a string comprised of 6 or 7 fields separated by white space. Fields can contain any of the allowed values, along with various combinations of the allowed special characters for that field. The fields are as follows:
| Field Name | Mandatory | Allowed Values | Allowed Special Characters |
|---|---|---|---|
| Seconds | YES | 0-59 | , - * / |
| Minutes | YES | 0-59 | , - * / |
| Hours | YES | 0-23 | , - * / |
| Day of month | YES | 1-31 | , - * ? / L W |
| Month | YES | 1-12 or JAN-DEC | , - * / |
| Day of week | YES | 1-7 or SUN-SAT | , - * ? / L # |
| Year | NO | empty, 1970-2099 | , - * / |
So cron expressions can be as simple as this: * * * * ? *
or more complex, like this: 0/5 14,18,3-39,52 * ? JAN,MAR,SEP MON-FRI 2002-2010
* ("all values") - used to select all values within a field. For example, "*" in the minute field means "every minute".
? ("no specific value") - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but do not care what day of the week that happens to be, I would put "10" in the day-of-month field, and "?" in the day-of-week field. See the examples below for clarification.
- - used to specify ranges. For example, "10-12" in the hour field means "the hours 10, 11 and 12".
, - used to specify additional values. For example, "MON,WED,FRI" in the day-of-week field means "the days Monday, Wednesday, and Friday".
/ - used to specify increments. For example, "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". You can also specify "/" after the character - in this case "/" is equivalent to having "0" before the "/". "1/3" in the day-of-month field means "fire every 3 days starting on the first day of the month".
L ("last") - has different meaning in each of the two fields in which it is allowed. For example, the value "L" in the day-of-month field means "the last day of the month" - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means "7" or "SAT". But if used in the day-of-week field after another value, it means "the last xxx day of the month" - for example "6L" means "the last friday of the month". You can also specify an offset from the last day of the month, such as "L-3" which would mean the third-to-last day of the calendar month. When using the "L" option, it is important not to specify lists, or ranges of values, as you will get confusing/unexpected results.
W ("weekday") - used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify "15W" as the value for the day-of-month field, the meaning is: "the nearest weekday to the 15th of the month". So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. However if you specify "1W" as the value for day-of-month, and the 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not jump over the boundary of days of the month. The "WW character can only be specified when the day-of-month is a single day, not a range or list of days.
The 'L' and 'W' characters can also be combined in the day-of-month field to yield 'LW', which translates to *"last weekday of the month"*.
The legal characters and the names of months and days of the week are not case sensitive. MON is the same as mon.
Here are some full examples:

| 0 11 11 11 11 ? | Fire every November 11th at 11:11am. |
Pay attention to the effects of '?' and '*' in the day-of-week and day-of-month fields!

Pulling all the strings together.
This week has been primarily focused on writing the script for the push primitive. I am fully threading it so that the modeling will be as close to the real time motion as possible.
Thankfully some of the other motion primitives have been successfully threaded already, such as the climb primitive and I can use that as an example. Also for anything I can't seem to figure out I will usually default to Michelle for assistance.
Scripting
When breaking down the script we have quite a few methods that are in play. You have motionTiming, mainThread_vision, initialize_vision, initialize_motion, and thread motion. All of these methods play an important part, but there are a few where we will have to take note. The way the push primitive works is in a series of stages. Previously the push primitive state machine would cycle between checking the angles of the various motors, actuating the motors that needed to be adjusted, droping the torque on the ones that were actuated, and lastly circling back to the check stage to see if they had all been corrected so it can end the program.
I will be primarily dealing with the threadMotion method and insert each of the strategies here. Within the push primitive exists the strategies of inch, straighten, and gather. The default strategy is to straighten, however, this does not always work so the inch and gather will be secondary attempts to get it over the obstacle.
This method will be dictated by the start and stop conditions contained in the method of mainThread_vision. Using the stages mentioned in the earlier paragraph these conditions can easily be recreated. There is one simple concern, since my motor checker functions by cycling through each joint then it would pick up the configuration of the entire snake. There may be certain scenarios where the pull primitive will be more applicable to successfully traverse the obstacle. So after walking through some common scenarios (which are pictured below) I have noticed a commonality. If the motor the fourth motor the snake is in a position where the joint between it and the third motor is not at 180 degrees then a push would be effective there. This will require some trials first to see if it is an effective start case.
Of course with a start case you also need an end case and the end cases are a combination of just the first two joints being bent out of place or the entire snake being flat.
What's next after this step?
When this is properly threaded with the motion then it will be able to fit into the coordinator and bring us one step closer to being able to execute a single run.

A. OVERVIEW: Over the past few years the UAE has developed into a popular base for businessmen, tourists and industrialists alike. Worldwide the UAE and Dubai in particular is becoming known as an ideal location for trade investment, distribution and manufacturing operations, as well as a first-class holiday destination featuring many of the finest leisure facilities available anywhere in the world. The sea-faring traditions of the Gulf are well known and even though traditional sailing ships, dhows continue to ply their trade across the Arabian Gulf, today's vessels are dominated by the power boats and pleasure craft which have become very popular in the UAE. Given the coastline attributes of this part of the world it is hardly surprising that watersports should be such a popular past-time here. A number of U.S. pleasure craft firms are represented in the UAE, such as the Boston Whaler, Glastron, Bayliner, Chapparal and Larson, but U.S. firms can still find capable businessmen interested in generating sales for products new to this market. The water jet ski has become very popular in the UAE and is a fast moving product line. B. MARKET ASSESSMENT: The UAE's pleasure craft market is based on the desire of individual nationals/expatriates to have their own pleasure craft. The sea is accessible within an hour's drive for the majority of the residents of the UAE. Local production is of a very high standard and offers quality at a very competitive price.  The UAE has a long coastline with no lakes or inland waterways. Therefore all pleasure craft are used in the sea, and most models purchased are seagoing vessels. Traditionally, low budget boat owners had to be content with small rowboats which were sometimes fitted with an inboard or outboard engine. Today, they have the option to purchase inflatable boats or small crafts which are light, fast and reliable. Lightweight boats are ideal for easy transport. However, inflatable boats are not very popular here as they are not very good for use on the open sea under rough weather conditions. These are mainly used for scuba diving. Another factor which works against inflatable boats is price. A good quality inflatable boat with accessories could cost almost the same as a small craft manufactured locally. Between 1988 and 1990 annual imports of pleasure crafts to the UAE grew from U.S. $ 5.3 million to U.S. $ 13.7 million, an average annual rate of 60% per year. The market's growth is expected to continue at an estimated average of 50% over the next 2-3 years. Total UAE imports during 1988-1990 were: 1988 U.S. $ 5.32 million, of which $ 1.9 million was for yachts and other pleasure vessels and $ 3.3 million for commercial vessels. 1989 U.S. $ 8.2 million, of which $ 3.2 million was for yachts and other pleasure vessels and $ 5.0 million for commercial vessels. 1990 U.S. $ 13.6 million, of which $ 4.5 million was for yachts and other pleasure vessels and $ 9.1 million for commercial vessels. The UAE's total market for pleasure craft in 1990 was estimated to be nearly U.S. $ 27.2 million. It is estimated that approximately 50% percent of this market demand is met by local production. The total market appears to have an annual growth rate of over 50%. Locally manufactured boats are popular as they are of a very high quality and available at very competitive prices. At present there is a joint venture between a British company and a local company. Another Japanese firm (Yamaha) have just started a joint venture with their local agents building their own boats in Dubai with production starting early September 1992. Market sources predict that boat prices will drop in the near future due to the stiff competition of these joint venture operations in the UAE. Though boats manufactured locally are of a very high standard, the local market in itself is not very big. Market sources estimate that approximately 60% of these boats are exported to other Gulf countries including Saudi Arabia, Kuwait and Bahrain. It speaks volumes when one considers that some Scandinavian countries are buying boats which are manufactured in the UAE as it is comparable to those manufactured in Europe. It is cheaper to produce a boat locally than in Europe due to low cost labor. The main deterrent to increased export sales to EC countries is high custom duties levied on non-EC manufacturers. American boats are not price competitive in the UAE any more when you take into consideration high shipping charges. American companies will have to seriously consider setting up joint ventures or their own manufacturing plants in the UAE if they want to maintain/increase market share. The important factors which have a bearing on who succeeds in this market, are price, service, promotion and commitment to the local agent. Support and quick response from suppliers are essential to success. Boat rental firms have been operating in the UAE for approximately 2 years. In popular demand for hire are water jet skis. C. COMPETITIVE SITUATION: In the coming years, U.S. exporters will be well advised not to ignore several new competitors that have appeared on the scene and are working to increase their market share. During the period 1988-1990, the U.S. share and its major competitors stood as follows: U.K. ITALY U.S. PAKISTAN TAIWAN JAPAN % % % % % % 1988 3.47 - 49.69 14.97 - 9.24 1989 14.85 33.22 19.76 10.0 - 3.97 1990 25.84 24.21 22.65 10.19 3.82 3.65 Domestic Production: The domestic boat industry is medium-sized and only directs 40% percent of its output to the local market. The other 60% are exported mainly to Saudi Arabia, Kuwait, Bahrain, Oman, Qater with a small percentage to France, the Maldive islands and Finland. There are currently approximately 40 boatbuilders in the entire UAE. However, the local shipyards are handicapped by the lack of a national motor manufacturer, which affects their competitiveness. For example, of the U.S. $43.65 outboard engine motors sold in 1990, all were imported. U.S. firms, such as Scat Hovercraft, Sunfish/Laser Inc., Wildcat Watercraft, Performance Catamarans Inc., Boston Whaler, Glastron, Chapparal have a presence in the UAE market. Their major competitors are Kawasaki and Yamaha of Japan, Bombardier SeaDoo from Canada. Most firms carry a limited volume of stock while some act only as suppliers. When local firms act as suppliers they usually place orders with the company only after they receive an order from a customer. On an average showrooms in Dubai have on display 5/6 crafts of local manufacture and 3-5 different kinds of water jet skis. According to industry contacts, the advantage that U.S. firms used to enjoy based on quality, reputation and service is fast being eroded as prices which have always been an important factor are no longer competitive. Promotion is also important but boat enthusiasts appear quite knowledgeable about the subject from reading reports and tests in foreign boat magazines. Local sources say that a boating magazine being prepared in the UAE is in the offing. For all cases, including pleasure boats and marine engines, all distributors/ agents provide service through their workshop, and usually offer a 6 month to a one-year guarantee. Local manufacturers generally offer a 2 year guarantee for the hull. Effective and well organized service is considered to be very important. Cost is an important competitive factor particularly in the lower to upper-middle price-range of the pleasure craft market. Price is less of a consideration at the top end of the market where purchasers are less likely to be concerned about discretionary income and expenditures. Other key competitive factors in the pleasure craft market are durability, safety, quality, style, design, speed, capacity, and accessories. It is not easy to sell a used boat in the UAE so the resale value is not a very important factor when buying a new boat though local market sources say that it is not uncommon for a local manufacturer of repute to be approached for boats which have been traded in for newer and faster models. D. MARKET ACCESS: The commercial climate in the UAE is one of free trade and competitiveness. There are no impediments to entering the market nor are there any laws regulating the imports of pleasure craft. English is the commercial language alongside Arabic but Arabic takes precedence in official documents with Government departments. Normal working hours are from 0730 or 0800 to 1330, except Thursday, when they close at 1200, for all government and public institutions (municipal offices, banks etc), while the private sector resumes for an afternoon session, usually from around 1600 to 1930. Some companies in the private sector have a five day week with the weekends usually being Thursday and Friday or Friday and Saturday. All government business must be accomplished during the five morning hours. (It is not unusual for a civil servant to operate a private business during evening hours.) No offices open for Friday, the day of rest. In order to enter the UAE market, U.S. firms must appoint an agent or a distributor. Local representation is a legal condition for doing business in the market. However, care is advised in the selection of an agent. In selection of an agent. U.S. suppliers are reminded that the U.A.E. Federal Agency Law No. 18 of 1981 and its 1989 amendments are applicable and should be reviewed carefully prior to appointing a local agent. The Agency law favors the local traders and cancellation of agency agreements and contracts are difficult and costly, regardless of the severance clauses included.. Frequent visits and strong agent support by the manufacturer both before and after the sale are the basic ingredients for success. The US&FCS can assist in identifying reputable representatives. Local sources say that the U.S. market share has been lost partly due to lack of loyalty on the part of American companies to the local agent. It is important to bear in mind that agents/distributors spend a lot of time and money in promoting a product in this area and when the product gains popularity, and an agency agreement has been signed, any inquiry received by the U.S. firm directly from any individual/company from the UAE should be routed through the local agent. Duty for import of pleasure craft is the usual 2%. Pleasure crafts are not presently required to be registered in the UAE. Local market sources say that very shortly the UAE Federal Ministry will be enforcing all owners of pleasure crafts in the UAE to have their boats registered. They expect this to be put in effect by end this year. Distribution and Business Practices: Domestic manufacturers sell through distributors and also directly to end users. Imported boats are generally retailed by distributors who carry a full spectrum of product lines. These importers tend to represent more than one manufacturer, frequently three or four, specializing in a specific product segment. The ability to meet specific client needs for optional equipment, timely delivery, as well as price are important factors to consider when selling U.S. pleasure crafts in the UAE. No safety standards are set locally but the trend is to go by the standards set by the U.S. coastguard. Approximately 10 marinas are in the UAE which are usually run by the large 5 star hotels or by boat clubs. Charges for mooring are high and vary in price from marina to marina. The charge is usually based on footage and on average could cost U.S. $ 1635/- per annum for a boat upto 20 feet. This charge apart from mooring the boat would usually include maintenance, boat washing and sometimes even battery charge. Many people who do not want to pay the high costs of berthing their boats at marinas moor them on buoys at sea, or keep them on trailers outside their homes. Sailing boats can also be kept on beaches. Public slipways for launching powerboats are available. E. TRADE PROMOTION OPPORTUNITIES: There is a wide range of services available for the U.S. exporter interested in entering the UAE market. Among these are: Agent/Distributor Service (ADS): assists in locating an agent. World Trader Data Report (WTDR): provides credit information on potential agents. Comparison Shopping Service: identifies the product's potential competitiveness in the market and also the best potential distributors. U.S. companies may display and promote their products in the only biennial exhibition held in Dubai, UAE.

export DPDK_DIR=/usr/src/dpdk-2.2
cd $DPDK_DIR
Update config/common_linuxapp
so that DPDK generate single lib file.
(modification also required for IVSHMEM build)
CONFIG_RTE_BUILD_COMBINE_LIBS=y
Then run make install
to build and install the library.
For default install without IVSHMEM:
make install T=x86_64-native-linuxapp-gcc
To include IVSHMEM (shared memory):
make install T=x86_64-ivshmem-linuxapp-gcc
For further details refer to http://dpdk.org/
Configure & build the Linux kernel:
Refer to intel-dpdk-getting-started-guide.pdf for understanding DPDK kernel requirement.
Configure & build OVS:
Non IVSHMEM:
export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc/
IVSHMEM:
export DPDK_BUILD=$DPDK_DIR/x86_64-ivshmem-linuxapp-gcc/
cd $(OVS_DIR)/
./boot.sh
./configure --with-dpdk=$DPDK_BUILD [CFLAGS="-g -O2 -Wno-cast-align"]
make
Note: 'clang' users may specify the '-Wno-cast-align' flag to suppress DPDK cast-align warnings.
To have better performance one can enable aggressive compiler optimizations and
use the special instructions(popcnt, crc32) that may not be available on all
machines. Instead of typing make
, type:
make CFLAGS='-O3 -march=native'
Refer to [INSTALL.userspace.md] for general requirements of building userspace OVS.
Setup system boot Add the following options to the kernel bootline:
default_hugepagesz=1GB hugepagesz=1G hugepages=1
Setup DPDK devices:
DPDK devices can be setup using either the VFIO (for DPDK 1.7+) or UIO modules. UIO requires inserting an out of tree driver igb_uio.ko that is available in DPDK. Setup for both methods are described below.
UIO:
modprobe uio
insmod $DPDK_BUILD/kmod/igb_uio.ko
$DPDK_DIR/tools/dpdk_nic_bind.py --bind=igb_uio eth1
VFIO:
VFIO needs to be supported in the kernel and the BIOS. More information can be found in the [DPDK Linux GSG].
modprobe vfio-pci
sudo /usr/bin/chmod a+x /dev/vfio
and: sudo /usr/bin/chmod 0666 /dev/vfio/*
$DPDK_DIR/tools/dpdk_nic_bind.py --bind=vfio-pci eth1
Mount the hugetable filesystem
mount -t hugetlbfs -o pagesize=1G none /dev/hugepages
Ref to http://www.dpdk.org/doc/quick-start for verifying DPDK setup.
Follow the instructions in [INSTALL.md] to install only the userspace daemons and utilities (via 'make install').
First time only db creation (or clearing):
mkdir -p /usr/local/etc/openvswitch
mkdir -p /usr/local/var/run/openvswitch
rm /usr/local/etc/openvswitch/conf.db
ovsdb-tool create /usr/local/etc/openvswitch/conf.db \
/usr/local/share/openvswitch/vswitch.ovsschema
Start ovsdb-server
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=Open_vSwitch,SSL,certificate \
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --pidfile --detach
First time after db creation, initialize:
ovs-vsctl --no-wait init
Start vswitchd:
DPDK configuration arguments can be passed to vswitchd via --dpdk
argument. This needs to be first argument passed to vswitchd process.
dpdk arg -c is ignored by ovs-dpdk, but it is a required parameter
for dpdk initialization.
export DB_SOCK=/usr/local/var/run/openvswitch/db.sock
ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach
If allocated more than one GB hugepage (as for IVSHMEM), set amount and use NUMA node 0 memory:
ovs-vswitchd --dpdk -c 0x1 -n 4 --socket-mem 1024,0 \
-- unix:$DB_SOCK --pidfile --detach
Add bridge & ports
To use ovs-vswitchd with DPDK, create a bridge with datapath_type "netdev" in the configuration database. For example:
ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
Now you can add dpdk devices. OVS expects DPDK device names to start with "dpdk" and end with a portid. vswitchd should print (in the log file) the number of dpdk devices found.
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk
ovs-vsctl add-port br0 dpdk1 -- set Interface dpdk1 type=dpdk
Once first DPDK port is added to vswitchd, it creates a Polling thread and polls dpdk device in continuous loop. Therefore CPU utilization for that thread is always 100%.
Note: creating bonds of DPDK interfaces is slightly different to creating bonds of system interfaces. For DPDK, the interface type must be explicitly set, for example:
ovs-vsctl add-bond br0 dpdkbond dpdk0 dpdk1 -- set Interface dpdk0 type=dpdk -- set Interface dpdk1 type=dpdk
Add test flows
Test flow script across NICs (assuming ovs in /usr/src/ovs): Execute script:
```
cd /usr/src/ovs/utilities/
./ovs-ofctl del-flows br0
./ovs-ofctl add-flow br0 inport=1,action=output:2 ./ovs-ofctl add-flow br0 inport=2,action=output:1 ```
PMD affinitization
A poll mode driver (pmd) thread handles the I/O of all DPDK interfaces assigned to it. A pmd thread will busy loop through the assigned port/rxq's polling for packets, switch the packets and send to a tx port if required. Typically, it is found that a pmd thread is CPU bound, meaning that the greater the CPU occupancy the pmd thread can get, the better the performance. To that end, it is good practice to ensure that a pmd thread has as many cycles on a core available to it as possible. This can be achieved by affinitizing the pmd thread with a core that has no other workload. See section 7 below for a description of how to isolate cores for this purpose also.
The following command can be used to specify the affinity of the pmd thread(s).
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=<hex string>
By setting a bit in the mask, a pmd thread is created and pinned to the corresponding CPU core. e.g. to run a pmd thread on core 1
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=2
For more information, please refer to the Open_vSwitch TABLE section in
man ovs-vswitchd.conf.db
Note, that a pmd thread on a NUMA node is only created if there is at least one DPDK interface from that NUMA node added to OVS.
Multiple poll mode driver threads
With pmd multi-threading support, OVS creates one pmd thread for each NUMA node by default. However, it can be seen that in cases where there are multiple ports/rxq's producing traffic, performance can be improved by creating multiple pmd threads running on separate cores. These pmd threads can then share the workload by each being responsible for different ports/rxq's. Assignment of ports/rxq's to pmd threads is done automatically.
The following command can be used to specify the affinity of the pmd threads.
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=<hex string>
A set bit in the mask means a pmd thread is created and pinned to the corresponding CPU core. e.g. to run pmd threads on core 1 and 2
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=6
For more information, please refer to the Open_vSwitch TABLE section in
man ovs-vswitchd.conf.db
For example, when using dpdk and dpdkvhostuser ports in a bi-directional VM loopback as shown below, spreading the workload over 2 or 4 pmd threads shows significant improvements as there will be more total CPU occupancy available.
NIC port0 <-> OVS <-> VM <-> OVS <-> NIC port 1
The OVS log can be checked to confirm that the port/rxq assignment to pmd threads is as required. This can also be checked with the following commands:
top -H
taskset -p <pid_of_pmd>
To understand where most of the pmd thread time is spent and whether the caches are being utilized, these commands can be used:
```
ovs-appctl dpif-netdev/pmd-stats-clear
ovs-appctl dpif-netdev/pmd-stats-show ```
DPDK port Rx Queues
ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=<integer>
The command above sets the number of rx queues for each DPDK interface. The rx queues are assigned to pmd threads on the same NUMA node in a round-robin fashion. For more information, please refer to the Open_vSwitch TABLE section in
man ovs-vswitchd.conf.db
Exact Match Cache
Each pmd thread contains one EMC. After initial flow setup in the datapath, the EMC contains a single table and provides the lowest level (fastest) switching for DPDK ports. If there is a miss in the EMC then the next level where switching will occur is the datapath classifier. Missing in the EMC and looking up in the datapath classifier incurs a significant performance penalty. If lookup misses occur in the EMC because it is too small to handle the number of flows, its size can be increased. The EMC size can be modified by editing the define EMFLOWHASH_SHIFT in lib/dpif-netdev.c.
As mentioned above an EMC is per pmd thread. So an alternative way of increasing the aggregate amount of possible flow entries in EMC and avoiding datapath classifier lookups is to have multiple pmd threads running. This can be done as described in section 2.
Compiler options
The default compiler optimization level is '-O2'. Changing this to more aggressive compiler optimizations such as '-O3' or '-Ofast -march=native' with gcc can produce performance gains.
Simultaneous Multithreading (SMT)
With SMT enabled, one physical core appears as two logical cores which can improve performance.
SMT can be utilized to add additional pmd threads without consuming additional physical cores. Additional pmd threads may be added in the same manner as described in section 2. If trying to minimize the use of physical cores for pmd threads, care must be taken to set the correct bits in the pmd-cpu-mask to ensure that the pmd threads are pinned to SMT siblings.
For example, when using 2x 10 core processors in a dual socket system with HT enabled, /proc/cpuinfo will report 40 logical cores. To use two logical cores which share the same physical core for pmd threads, the following command can be used to identify a pair of logical cores.
cat /sys/devices/system/cpu/cpuN/topology/thread_siblings_list
where N is the logical core number. In this example, it would show that cores 1 and 21 share the same physical core. The pmd-cpu-mask to enable two pmd threads running on these two logical cores (one physical core) is.
ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=100002
Note that SMT is enabled by the Hyper-Threading section in the BIOS, and as such will apply to the whole system. So the impact of enabling/disabling it for the whole system should be considered e.g. If workloads on the system can scale across multiple cores, SMT may very beneficial. However, if they do not and perform best on a single physical core, SMT may not be beneficial.
The isolcpus kernel boot parameter
isolcpus can be used on the kernel bootline to isolate cores from the kernel scheduler and hence dedicate them to OVS or other packet forwarding related workloads. For example a Linux kernel boot-line could be:
'GRUBCMDLINELINUXDEFAULT="quiet hugepagesz=1G hugepages=4 defaulthugepagesz=1G 'intel_iommu=off' isolcpus=1-19"'
NUMA/Cluster On Die
Ideally inter NUMA datapaths should be avoided where possible as packets will go across QPI and there may be a slight performance penalty when compared with intra NUMA datapaths. On Intel Xeon Processor E5 v3, Cluster On Die is introduced on models that have 10 cores or more. This makes it possible to logically split a socket into two NUMA regions and again it is preferred where possible to keep critical datapaths within the one cluster.
It is good practice to ensure that threads that are in the datapath are pinned to cores in the same NUMA area. e.g. pmd threads and QEMU vCPUs responsible for forwarding.
Rx Mergeable buffers
Rx Mergeable buffers is a virtio feature that allows chaining of multiple virtio descriptors to handle large packet sizes. As such, large packets are handled by reserving and chaining multiple free descriptors together. Mergeable buffer support is negotiated between the virtio driver and virtio device and is supported by the DPDK vhost library. This behavior is typically supported and enabled by default, however in the case where the user knows that rx mergeable buffers are not needed i.e. jumbo frames are not needed, it can be forced off by adding mrg_rxbuf=off to the QEMU command line options. By not reserving multiple chains of descriptors it will make more individual virtio descriptors available for rx to the guest using dpdkvhost ports and this can improve performance.
Packet processing in the guest
It is good practice whether simply forwarding packets from one
interface to another or more complex packet processing in the guest,
to ensure that the thread performing this work has as much CPU
occupancy as possible. For example when the DPDK sample application
testpmd
is used to forward packets in the guest, multiple QEMU vCPU
threads can be created. Taskset can then be used to affinitize the
vCPU thread responsible for forwarding to a dedicated core not used
for other general processing on the host system.
DPDK virtio pmd in the guest
dpdkvhostcuse or dpdkvhostuser ports can be used to accelerate the path
to the guest using the DPDK vhost library. This library is compatible with
virtio-net drivers in the guest but significantly better performance can
be observed when using the DPDK virtio pmd driver in the guest. The DPDK
testpmd
application can be used in the guest as an example application
that forwards packet from one DPDK vhost port to another. An example of
running testpmd
in the guest can be seen here.
./testpmd -c 0x3 -n 4 --socket-mem 512 -- --burst=64 -i --txqflags=0xf00 --disable-hw-vlan --forward-mode=io --auto-start
See below information on dpdkvhostcuse and dpdkvhostuser ports.
See [DPDK Docs] for more information on testpmd
.
Following the steps above to create a bridge, you can now add dpdk rings as a port to the vswitch. OVS will expect the DPDK ring device name to start with dpdkr and end with a portid.
ovs-vsctl add-port br0 dpdkr0 -- set Interface dpdkr0 type=dpdkr
DPDK rings client test application
Included in the test directory is a sample DPDK application for testing the rings. This is from the base dpdk directory and modified to work with the ring naming used within ovs.
location tests/ovs_client
To run the client :
cd /usr/src/ovs/tests/
ovsclient -c 1 -n 4 --proc-type=secondary -- -n "port id you gave dpdkr"
In the case of the dpdkr example above the "port id you gave dpdkr" is 0.
It is essential to have --proc-type=secondary
The application simply receives an mbuf on the receive queue of the ethernet ring and then places that same mbuf on the transmit ring of the ethernet ring. It is a trivial loopback application.
In addition to executing the client in the host, you can execute it within a guest VM. To do so you will need a patched qemu. You can download the patch and getting started guide at :
https://01.org/packet-processing/downloads
A general rule of thumb for better performance is that the client application should not be assigned the same dpdk core mask "-c" as the vswitchd.
DPDK 2.2 supports two types of vhost:
Whatever type of vhost is enabled in the DPDK build specified, is the type that will be enabled in OVS. By default, vhost-user is enabled in DPDK. Therefore, unless vhost-cuse has been enabled in DPDK, vhost-user ports will be enabled in OVS. Please note that support for vhost-cuse is intended to be deprecated in OVS in a future release.
The following sections describe the use of vhost-user 'dpdkvhostuser' ports with OVS.
DPDK 2.2 with vhost support enabled as documented in the "Building and Installing section"
QEMU version v2.1.0+
QEMU v2.1.0 will suffice, but it is recommended to use v2.2.0 if providing your VM with memory greater than 1GB due to potential issues with memory mapping larger areas.
Following the steps above to create a bridge, you can now add DPDK vhost-user as a port to the vswitch. Unlike DPDK ring ports, DPDK vhost-user ports can have arbitrary names, except that forward and backward slashes are prohibited in the names.
For vhost-user, the name of the port type is dpdkvhostuser
ovs-vsctl add-port br0 vhost-user-1 -- set Interface vhost-user-1
type=dpdkvhostuser
This action creates a socket located at
/usr/local/var/run/openvswitch/vhost-user-1
, which you must provide
to your VM on the QEMU command line. More instructions on this can be
found in the next section "DPDK vhost-user VM configuration"
Note: If you wish for the vhost-user sockets to be created in a
directory other than /usr/local/var/run/openvswitch
, you may specify
another location on the ovs-vswitchd command line like so:
./vswitchd/ovs-vswitchd --dpdk -vhost_sock_dir /my-dir -c 0x1 ...
Follow the steps below to attach vhost-user port(s) to a VM.
Configure sockets. Pass the following parameters to QEMU to attach a vhost-user device:
-chardev socket,id=char1,path=/usr/local/var/run/openvswitch/vhost-user-1
-netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce
-device virtio-net-pci,mac=00:00:00:00:00:01,netdev=mynet1
...where vhost-user-1 is the name of the vhost-user port added to the switch. Repeat the above parameters for multiple devices, changing the chardev path and id as necessary. Note that a separate and different chardev path needs to be specified for each vhost-user device. For example you have a second vhost-user port named 'vhost-user-2', you append your QEMU command line with an additional set of parameters:
-chardev socket,id=char2,path=/usr/local/var/run/openvswitch/vhost-user-2
-netdev type=vhost-user,id=mynet2,chardev=char2,vhostforce
-device virtio-net-pci,mac=00:00:00:00:00:02,netdev=mynet2
Configure huge pages. QEMU must allocate the VM's memory on hugetlbfs. vhost-user ports access a virtio-net device's virtual rings and packet buffers mapping the VM's physical memory on hugetlbfs. To enable vhost-user ports to map the VM's memory into their process address space, pass the following paramters to QEMU:
-object memory-backend-file,id=mem,size=4096M,mem-path=/dev/hugepages,
share=on
-numa node,memdev=mem -mem-prealloc
Optional: Enable multiqueue support QEMU needs to be configured with multiple queues and the number queues must be less or equal to Open vSwitch other_config:n-dpdk-rxqs. The $q below is the number of queues. The $v is the number of vectors, which is '$q x 2 + 2'.
-chardev socket,id=char2,path=/usr/local/var/run/openvswitch/vhost-user-2
-netdev type=vhost-user,id=mynet2,chardev=char2,vhostforce,queues=$q
-device virtio-net-pci,mac=00:00:00:00:00:02,netdev=mynet2,mq=on,vectors=$v
If one wishes to use multiple queues for an interface in the guest, the driver in the guest operating system must be configured to do so. It is recommended that the number of queues configured be equal to '$q'.
For example, this can be done for the Linux kernel virtio-net driver with:
ethtool -L <DEV> combined <$q>
A note on the command above:
-L
: Changes the numbers of channels of the specified network device
combined
: Changes the number of multi-purpose channels.
The following sections describe the use of vhost-cuse 'dpdkvhostcuse' ports with OVS.
DPDK 2.2 with vhost support enabled as documented in the "Building and
Installing section"
As an additional step, you must enable vhost-cuse in DPDK by setting the
following additional flag in config/common_linuxapp
:
CONFIG_RTE_LIBRTE_VHOST_USER=n
Following this, rebuild DPDK as per the instructions in the "Building and Installing" section. Finally, rebuild OVS as per step 3 in the "Building and Installing" section - OVS will detect that DPDK has vhost-cuse libraries compiled and in turn will enable support for it in the switch and disable vhost-user support.
Insert the Cuse module:
modprobe cuse
Build and insert the eventfd_link
module:
cd $DPDK_DIR/lib/librte_vhost/eventfd_link/
make
insmod $DPDK_DIR/lib/librte_vhost/eventfd_link.ko
QEMU version v2.1.0+
vhost-cuse will work with QEMU v2.1.0 and above, however it is recommended to use v2.2.0 if providing your VM with memory greater than 1GB due to potential issues with memory mapping larger areas. Note: QEMU v1.6.2 will also work, with slightly different command line parameters, which are specified later in this document.
Following the steps above to create a bridge, you can now add DPDK vhost-cuse as a port to the vswitch. Unlike DPDK ring ports, DPDK vhost-cuse ports can have arbitrary names.
For vhost-cuse, the name of the port type is dpdkvhostcuse
ovs-vsctl add-port br0 vhost-cuse-1 -- set Interface vhost-cuse-1
type=dpdkvhostcuse
When attaching vhost-cuse ports to QEMU, the name provided during the add-port operation must match the ifname parameter on the QEMU command line. More instructions on this can be found in the next section.
vhost-cuse ports use a Linux* character device to communicate with QEMU.
By default it is set to /dev/vhost-net
. It is possible to reuse this
standard device for DPDK vhost, which makes setup a little simpler but it
is better practice to specify an alternative character device in order to
avoid any conflicts if kernel vhost is to be used in parallel.
This step is only needed if using an alternative character device.
The new character device filename must be specified on the vswitchd commandline:
`./vswitchd/ovs-vswitchd --dpdk --cuse_dev_name my-vhost-net -c 0x1 ...`
Note that the --cuse_dev_name
argument and associated string must be the first
arguments after --dpdk
and come before the EAL arguments. In the example
above, the character device to be used will be /dev/my-vhost-net
.
This step is only needed if reusing the standard character device. It will conflict with the kernel vhost character device so the user must first remove it.
rm -rf /dev/vhost-net
3a. Configure virtio-net adaptors: The following parameters must be passed to the QEMU binary:
```
-netdev tap,id=<id>,script=no,downscript=no,ifname=<name>,vhost=on
-device virtio-net-pci,netdev=net1,mac=<mac>
```
Repeat the above parameters for multiple devices.
The DPDK vhost library will negiotiate its own features, so they
need not be passed in as command line params. Note that as offloads are
disabled this is the equivalent of setting:
`csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off`
3b. If using an alternative character device. It must be also explicitly
passed to QEMU using the vhostfd
argument:
```
-netdev tap,id=<id>,script=no,downscript=no,ifname=<name>,vhost=on,
vhostfd=<open_fd>
-device virtio-net-pci,netdev=net1,mac=<mac>
```
The open file descriptor must be passed to QEMU running as a child
process. This could be done with a simple python script.
```
#!/usr/bin/python
fd = os.open("/dev/usvhost", os.O_RDWR)
subprocess.call("qemu-system-x86_64 .... -netdev tap,id=vhostnet0,\
vhost=on,vhostfd=" + fd +"...", shell=True)
Alternatively the qemu-wrap.py
script can be used to automate the
requirements specified above and can be used in conjunction with libvirt if
desired. See the "DPDK vhost VM configuration with QEMU wrapper" section
below.
Configure huge pages: QEMU must allocate the VM's memory on hugetlbfs. Vhost ports access a virtio-net device's virtual rings and packet buffers mapping the VM's physical memory on hugetlbfs. To enable vhost-ports to map the VM's memory into their process address space, pass the following parameters to QEMU:
-object memory-backend-file,id=mem,size=4096M,mem-path=/dev/hugepages,
share=on -numa node,memdev=mem -mem-prealloc
Note: For use with an earlier QEMU version such as v1.6.2, use the following to configure hugepages instead:
-mem-path /dev/hugepages -mem-prealloc
The QEMU wrapper script automatically detects and calls QEMU with the necessary parameters. It performs the following actions:
Before use, you must edit the configuration parameters section of the
script to point to the correct emulator location and set additional
settings. Of these settings, emul_path
and us_vhost_path
must be
set. All other settings are optional.
To use directly from the command line simply pass the wrapper some of the QEMU parameters: it will configure the rest. For example:
qemu-wrap.py -cpu host -boot c -hda <disk image> -m 4096 -smp 4
--enable-kvm -nographic -vnc none -net none -netdev tap,id=net1,
script=no,downscript=no,ifname=if1,vhost=on -device virtio-net-pci,
netdev=net1,mac=00:00:00:00:00:01
If you are using libvirt, you must enable libvirt to access the character device by adding it to controllers cgroup for libvirtd using the following steps.
1. In `/etc/libvirt/qemu.conf` add/edit the following lines:
```
1) clear_emulator_capabilities = 0
2) user = "root"
3) group = "root"
4) cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc", "/dev/hpet", "/dev/net/tun",
"/dev/<my-vhost-device>",
"/dev/hugepages"]
```
<my-vhost-device> refers to "vhost-net" if using the `/dev/vhost-net`
device. If you have specificed a different name on the ovs-vswitchd
commandline using the "--cuse_dev_name" parameter, please specify that
filename instead.
2. Disable SELinux or set to permissive mode
3. Restart the libvirtd process
For example, on Fedora:
`systemctl restart libvirtd.service`
After successfully editing the configuration, you may launch your
vhost-enabled VM. The XML describing the VM can be configured like so
within the
1. Set up shared hugepages:
```
<qemu:arg value='-object'/>
<qemu:arg value='memory-backend-file,id=mem,size=4096M,mem-path=/dev/hugepages,share=on'/>
<qemu:arg value='-numa'/>
<qemu:arg value='node,memdev=mem'/>
<qemu:arg value='-mem-prealloc'/>
```
2. Set up your tap devices:
```
<qemu:arg value='-netdev'/>
<qemu:arg value='type=tap,id=net1,script=no,downscript=no,ifname=vhost0,vhost=on'/>
<qemu:arg value='-device'/>
<qemu:arg value='virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01'/>
```
Repeat for as many devices as are desired, modifying the id, ifname
and mac as necessary.
Again, if you are using an alternative character device (other than
`/dev/vhost-net`), please specify the file descriptor like so:
`<qemu:arg value='type=tap,id=net3,script=no,downscript=no,ifname=vhost0,vhost=on,vhostfd=<open_fd>'/>`
Where <open_fd> refers to the open file descriptor of the character device.
Instructions of how to retrieve the file descriptor can be found in the
"DPDK vhost VM configuration" section.
Alternatively, the process is automated with the qemu-wrap.py script,
detailed in the next section.
Now you may launch your VM using virt-manager, or like so:
`virsh create my_vhost_vm.xml`
To use the qemu-wrapper script in conjuntion with libvirt, follow the steps in the previous section before proceeding with the following steps:
Place qemu-wrap.py
in libvirtd's binary search PATH ($PATH)
Ideally in the same directory that the QEMU binary is located.
Ensure that the script has the same owner/group and file permissions as the QEMU binary.
Update the VM xml file using "virsh edit VM.xml"
Set the VM to use the launch script.
Set the emulator path contained in the <emulator><emulator/>
tags.
For example, replace:
`<emulator>/usr/bin/qemu-kvm<emulator/>`
with:
`<emulator>/usr/bin/qemu-wrap.py<emulator/>`
Edit the Configuration Parameters section of the script to point to the correct emulator location and set any additional options. If you are using a alternative character device name, please set "usvhostpath" to the location of that device. The script will automatically detect and insert the correct "vhostfd" value in the QEMU command line arguments.
Use virt-manager to launch the VM
Please note that additional configuration is required if you want to run ovs-vswitchd with DPDK backend inside a QEMU virtual machine. Ovs-vswitchd creates separate DPDK TX queues for each CPU core available. This operation fails inside QEMU virtual machine because, by default, VirtIO NIC provided to the guest is configured to support only single TX queue and single RX queue. To change this behavior, you need to turn on 'mq' (multiqueue) property of all virtio-net-pci devices emulated by QEMU and used by DPDK. You may do it manually (by changing QEMU command line) or, if you use Libvirt, by adding the following string:
<driver name='vhost' queues='N'/>
to
DPDK-vHost support works with 1G huge pages.
ivshmem:
If you run Open vSwitch with smaller page sizes (e.g. 2MB), you may be unable to share any rings or mempools with a virtual machine. This is because the current implementation of ivshmem works by sharing a single 1GB huge page from the host operating system to any guest operating system through the Qemu ivshmem device. When using smaller page sizes, multiple pages may be required to hold the ring descriptors and buffer pools. The Qemu ivshmem device does not allow you to share multiple file descriptors to the guest operating system. However, if you want to share dpdkr rings with other processes on the host, you can do this with smaller page sizes.
Platform and Network Interface:
By default with DPDK 2.2, a maximum of 64 TX queues can be used with an
Intel XL710 Network Interface on a platform with more than 64 logical
cores. If a user attempts to add an XL710 interface as a DPDK port type to
a system as described above, an error will be reported that initialization
failed for the 65th queue. OVS will then roll back to the previous
successful queue initialization and use that value as the total number of
TX queues available with queue locking. If a user wishes to use more than
64 queues and avoid locking, then the
CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_PF
config parameter in DPDK must be
increased to the desired number of queues. Both DPDK and OVS must be
recompiled for this change to take effect.

I moved down from my hometown of Missoula, Montana to Portland in 2005 and welded rail cars. Prior to that I worked in Chicago at the CBOE (Chicago Board Options Exchange.) After welding, I went to work at the then first Google built and designed datacenter for 13 years qualifying and stress testing hardware and servers. Due to personal issues and a long commute, I am currently unemployed. I have some experience with bash and linux but never was able to immerse myself in coding, thus, I signed up for Epicodus!
I currently live in Portland Oregon with my son Jonah, and daughter Arya. We have two cute Manx cats (Mirai and Kaden), three chickens and one duck (Rena Rainbow.)


INTRO
The n2o_pi module dedicated for creating and tracking supervised processes across all applications, using any ETS tables. Any supervised process in N2O is created using n2o_pi, such as: ring vnodes, timers, authorization, web page processes, test processes and other services. Loop process inside info/2 protocol handlers should spawn new async processes proc/2 in case of time consuming operations, because protocol handler is a critical path and it should be handled as soon as possible.
CALLBACK
The proc/2 is a callback that will be called on each gen_server's calls: handle_call, handle_cast and handle_info, its init and terminate. It returns either #ok as initial state of the process (which is the #pi{} too) or its response to gen_server:call/2 with new state included in #reply.
EXAMPLE
Here is literal implementation of N2O Timer which invalidates the caching table used for session variables.
Main purpose of n2o_pi is to create such processes from single proc/2 function and track pid in ETS table which is specified during process #pi{} initialization.
RECORDS
Each process is driven by its protocol which in fact a sum of protocol messages. Though n2o_pi as being generic don't limit the protocol messages, however it defines the type of process state, the #pi{} record.
According to N2O agreement each protocol message filed should include [] in its type as default nil.
- name — process name, key in supervised chain.
- module — the module name where proc/2 is placed.
- table — ETS table name where cached pids are stored.
- sup — the application, where supervised processes will be created.
- state — the state of the running supervised process.
API
Spawns proc/2 function inside a process under supervision.
Kills the process and remove from supervision.
Tries to stop the process. On success it starts the new one, else return error.
Sends gen_call message to process, taken from Class table with Name key. Returns the response from gen_server:call.
Returns pid that was stored during process initialization in Class table with Name key.

Money Play. How should Red play 33?
pips Red=151 White=159
(CorrectAnswer= 0/0, ErrorScore= 0)
Most people who see this position anchor on White’s bar-point and then find some way to play the other two threes. The problem with this approach is how to bring it home with that bar-point still to clear.
The only move that is not an outright blunder is 24/15, 18/15. If Red hits the blot he has to give up his anchor at a time when he doesn’t have any new points in his home board. If he doesn’t hit Red is creeping his way to a very efficient double.
This is one of those plays that once you see it, it becomes obvious. The issue is seeing beyond leaving a blot when there is no apparent need. However, Red’s game plan is to race and that is precisely what he should do here.

The Text object is used to show static or dynamic text in a model. Text objects are used for labelling various parts of the model and for monitoring the status of the model.
The output displayed by the Text object is determined primarily by its Format keyword. Dynamic text can be introduced by including a Java format code such as %s in the Format keyword and specifying the value to be displayed with the DataSource keyword. Some typical Java format codes are %s, which can display both text and numbers, %.6f, which displays a numeric value with six decimal places, and %n, which starts a new line.
If the variable text is a number with units, the value can be converted from SI to a specified unit through the Unit keyword.
The easiest way to modify the contents of a Text object is to edit it directly in the view window. Double-click on the object or press the F2 key to place it in edit mode. In this mode, text can be entered, deleted, inserted, and highlighted using the same conventions as a typical text editor. Text can be copied from and pasted to the clipboard using Ctrl-C and Ctrl-V. A new line can be started at any point in the text by pressing Ctrl-Enter. Press the Return key or click on another object to save the changes and return the Text object to its normal mode. Press the Escape key to terminate editing and restore the original text.
The appearance and style of the text is determined by the keywords under the Font tab, including FontName, FontColour, etc. If no inputs are provided to these keywords, the appearance of the text is determined by the TextModel entered for the DisplayModel keyword. The default TextModel is set to the black Verdana font.
TextModels can be used in the same way as the Text Styles in Microsoft Word. A new TextModel can be created through the following steps:
1. In the Object Selector, right‑click on the TextModelDefault object and select Duplicate.
2. Rename the new TextModel object by clicking on its name in the Object Selector, entering the new name.
3. With the new TextModel selected in the Object Selector, use the formatting buttons in the button bar to specify its characteristics such as font, font style, colour, etc.
The new TextModel can be applied to the Text object by clicking the object and using the 'DisplayModel' button in the button bar.

If the user did not choose a file (i.e. hit the Cancel button in the dialog), the function returns "" (the empty string).
Note: This function is not available in the current version of the GUI Procedure Library (shipping with Turing 4.0 and MacOOT 1.5). It is documented here for use with future shipping version of Turing. Check the release notes that are found in the on-line help to find out if this function is now available.
import GUI in "%oot/lib/GUI"
var fileName : string
var streamNumber : int
fileName := GUI.SaveFile ("Choose a Text File")
open : streamNumber, fileName, put
assert streamNumber > 0
for i : 1 .. 10
put : streamNumber, i
end loop
close : streamNumber
This means that you can only call the function by calling GUI.SaveFile, not by calling SaveFile.


Shops, businesses shut for third consecutive day in J&K
by PTIMost shops and other business establishments in Kashmir were closed on Friday, the third consecutive day of a Valley-wide shutdown following a brief semblance of normalcy.
On Wednesday, posters warning shopkeepers and public transport operators appeared at several places in the city and elsewhere in the Valley, officials said.
Main markets in the city and most other areas in the Valley were shut and shops did not open even for a few hours in the morning as they had been doing for the last few weeks. Public transport was also largely off the roads, officials said.
