-Test Environment\r
-================\r
-\r
-CSIT functional tests are currently executed in FD.IO VIRL testbed. The physical\r
-VIRL testbed infrastructure consists of three VIRL hosts:\r
-\r
-- All hosts are Cisco UCS C240-M4 (2x Intel(R) Xeon(R) CPU E5-2699 v3 @2.30GHz,\r
- 18c, 512GB RAM)\r
-- tb4-virl1:\r
-\r
- - Status: Production\r
- - OS: Ubuntu 16.04.2\r
- - STD server version 0.10.32.16\r
- - UWM server version 0.10.32.16\r
-\r
-- tb4-virl2:\r
-\r
- - Status: Production\r
- - OS: Ubuntu 16.04.2\r
- - STD server version 0.10.32.16\r
- - UWM server version 0.10.32.16\r
-\r
-- tb4-virl3:\r
-\r
- - Status: Production\r
- - OS: Ubuntu 14.04.3\r
- - STD server version 0.10.24.7\r
- - UWM server version 0.10.24.7\r
-\r
-Whenever a patch is submitted to gerrit for review, parallel VIRL simulations\r
-are started to reduce the time of execution of all functional tests. The number\r
-of parallel VIRL simulations is equal to number of test groups defined by\r
-TEST_GROUPS variable in :file:`csit/bootstrap.sh` file. The VIRL host to run\r
-VIRL simulation is selected based on least load algorithm per VIRL simulation.\r
-\r
-Every VIRL simulation uses the same three-node - Traffic Generator (TG node) and\r
-two Systems Under Test (SUT1 and SUT2) - "double-ring" topology. The appropriate\r
-pre-built VPP packages built by Jenkins for the patch under review are then\r
-installed on the two SUTs, along with their :file:`/etc/vpp/startup.conf` file,\r
-in all VIRL simulations.\r
-\r
-SUT Configuration - VIRL Guest VM\r
----------------------------------\r
-\r
-Configurations of the SUT VMs is defined in `VIRL topologies directory`_\r
-\r
-- List of SUT VM interfaces:::\r
-\r
- <interface id="0" name="GigabitEthernet0/4/0"/>\r
- <interface id="1" name="GigabitEthernet0/5/0"/>\r
- <interface id="2" name="GigabitEthernet0/6/0"/>\r
- <interface id="3" name="GigabitEthernet0/7/0"/>\r
-\r
-- Number of 2MB hugepages: 1024\r
-\r
-- Maximum number of memory map areas: 20000\r
-\r
-- Kernel Shared Memory Max: 2147483648 (vm.nr_hugepages * 2 * 1024 * 1024)\r
-\r
-SUT Configuration - VIRL Guest OS Linux\r
----------------------------------------\r
-\r
-In CSIT terminology, the VM operating system for both SUTs that |vpp-release| has\r
-been tested with, is the following:\r
-\r
-#. **Ubuntu VIRL image**\r
-\r
- This image implies Ubuntu 16.04.1 LTS, current as of yyyy-mm-dd (that is,\r
- package versions are those that would have been installed by a\r
- :command:`apt-get update`, :command:`apt-get upgrade` on that day), produced\r
- by CSIT disk image build scripts.\r
-\r
- The exact list of installed packages and their versions (including the Linux\r
- kernel package version) are included in `VIRL images lists`_.\r
-\r
- A replica of this VM image can be built by running the :command:`build.sh`\r
- script in CSIT repository.\r
-\r
-#. **CentOS VIRL image**\r
-\r
- The Centos7.3 image is ready to be used but no tests running on it now.\r
- Corresponding Jenkins jobs are under preparation.\r
-\r
- The exact list of installed packages and their versions (including the Linux\r
- kernel package version) are included in `VIRL images lists`_.\r
-\r
- A replica of this VM image can be built by running the :command:`build.sh`\r
- script in CSIT repository.\r
-\r
-#. **Nested VM image**\r
-\r
- In addition to the "main" VM image, tests which require VPP to communicate to\r
- a VM over a vhost-user interface, utilize a "nested" VM image.\r
-\r
- This "nested" VM is dynamically created and destroyed as part of a test case,\r
- and therefore the "nested" VM image is optimized to be small, lightweight and\r
- have a short boot time. The "nested" VM image is not built around any\r
- established Linux distribution, but is based on `BuildRoot\r
- <https://buildroot.org/>`_, a tool for building embedded Linux systems. Just\r
- as for the "main" image, scripts to produce an identical replica of the\r
- "nested" image are included in CSIT GIT repository, and the image can be\r
- rebuilt using the "build.sh" script at `VIRL nested`_.\r
-\r
-DUT Configuration - VPP\r
------------------------\r
-\r
-Every System Under Test runs VPP SW application in Linux user-mode as a Device\r
-Under Test (DUT) node.\r
-\r
-**DUT port configuration**\r
-\r
-Port configuration of DUTs is defined in topology file that is generated per\r
-VIRL simulation based on the definition stored in `VIRL topologies directory`_.\r
-\r
-Example of DUT nodes configuration:::\r
-\r
- DUT1:\r
- type: DUT\r

+Test Environment
+================
+
+CSIT VPP functional tests are executed in FD.io VIRL testbeds. The
+physical VIRL testbed infrastructure consists of three VIRL servers:
+
+- tb4-virl1:
+
+ - Status: Production
+ - OS: Ubuntu 16.04.2
+ - VIRL STD server version: 0.10.32.16
+ - VIRL UWM server version: 0.10.32.16
+
+- tb4-virl2:
+
+ - Status: Production
+ - OS: Ubuntu 16.04.2
+ - VIRL STD server version: 0.10.32.16
+ - VIRL UWM server version: 0.10.32.16
+
+- tb4-virl3:
+
+ - Status: Production
+ - OS: Ubuntu 16.04.2
+ - VIRL STD server version: 0.10.32.19
+ - VIRL UWM server version: 0.10.32.19
+
+- VIRL hosts: Cisco UCS C240-M4, each with 2x Intel Xeon E5-2699
+ v3 (2.30 GHz, 18c), 512GB RAM.
+
+Whenever a patch is submitted to gerrit for review, parallel VIRL
+simulations are started to reduce the time of execution of all
+functional tests. The number of parallel VIRL simulations is equal to a
+number of test groups defined by TEST_GROUPS variable in
+:file:`csit/bootstrap.sh` file. VIRL host to run VIRL simulation is
+selected based on least load algorithm per VIRL simulation.
+
+Every VIRL simulation uses the same three-node logical ring topology -
+Traffic Generator (TG node) and two Systems Under Test (SUT1 and SUT2).
+The appropriate pre-built VPP packages built by Jenkins for the patch
+under review are then installed on the two SUTs, along with their
+:file:`/etc/vpp/startup.conf` file, in all VIRL simulations.
+
+SUT Settings - VIRL Guest VM
+----------------------------
+
+SUT VMs' settings are defined in `VIRL topologies directory`_
+
+- List of SUT VM interfaces:
+
+ <interface id="0" name="GigabitEthernet0/4/0"/>
+ <interface id="1" name="GigabitEthernet0/5/0"/>
+ <interface id="2" name="GigabitEthernet0/6/0"/>
+ <interface id="3" name="GigabitEthernet0/7/0"/>
+
+- Number of 2MB hugepages: 1024.
+
+- Maximum number of memory map areas: 20000.
+
+- Kernel Shared Memory Max: 2147483648 (vm.nr_hugepages * 2 * 1024 * 1024).
+
+SUT Settings - VIRL Guest OS Linux
+----------------------------------
+
+In CSIT terminology, the VM operating system for both SUTs that |vpp-release|
+has been tested with, is the following:
+
+#. Ubuntu VIRL image
+
+ This image implies Ubuntu 16.04.1 LTS, current as of yyyy-mm-dd (that is,
+ package versions are those that would have been installed by a
+ :command:`apt-get update`, :command:`apt-get upgrade` on that day), produced
+ by CSIT disk image build scripts.
+
+ The exact list of installed packages and their versions (including the Linux
+ kernel package version) are included in `VIRL ubuntu images lists`_.
+
+ A replica of this VM image can be built by running the :command:`build.sh`
+ script in CSIT repository.
+
+#. CentOS VIRL image
+
+ This image implies Centos 7.4-1711, current as of yyyy-mm-dd (that is,
+ package versions are those that would have been installed by a
+ :command:`yum update`, :command:`yum upgrade` on that day), produced
+ by CSIT disk image build scripts.
+
+ The exact list of installed packages and their versions (including the Linux
+ kernel package version) are included in `VIRL centos images lists`_.
+
+ A replica of this VM image can be built by running the :command:`build.sh`
+ script in CSIT repository.
+
+#. Nested VM image
+
+ In addition to the "main" VM image, tests which require VPP to communicate to
+ a VM over a vhost-user interface, utilize a "nested" VM image.
+
+ This "nested" VM is dynamically created and destroyed as part of a test case,
+ and therefore the "nested" VM image is optimized to be small, lightweight and
+ have a short boot time. The "nested" VM image is not built around any
+ established Linux distribution, but is based on `BuildRoot
+ <https://buildroot.org/>`_, a tool for building embedded Linux systems. Just
+ as for the "main" image, scripts to produce an identical replica of the
+ "nested" image are included in CSIT GIT repository, and the image can be
+ rebuilt using the "build.sh" script at `VIRL nested`_.
+
+DUT Settings - VPP
+------------------
+
+Every System Under Test runs VPP SW application in Linux user-mode as a Device
+Under Test (DUT) node.
+
+DUT Port Configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+Port configuration of DUTs is defined in topology file that is generated per
+VIRL simulation based on the definition stored in `VIRL topologies directory`_.
+
+Example of DUT nodes configuration:
+
+::
+
+ DUT1:
