+Test Environment\r
+================\r
+\r
+CSIT NSH_SFC functional tests are currently executed in FD.IO VIRL testbed. The\r
+physical VIRL testbed infrastructure consists of three identical 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
+- Hosts run Ubuntu 14.04.3\r
+- VIRL software versions:\r
+\r
+ - STD server version 0.10.24.7\r
+ - UWM server version 0.10.24.7\r
+\r
+The VIRL host to run VIRL simulation is selected based on least load algorithm\r
+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 /etc/vpp/startup.conf file, in all\r
+VIRL simulations.\r
+\r
+SUT Configuration - VIRL Guest VM\r
+---------------------------------\r
+\r
+Configuration of the SUT VMs is defined in file\r
+\r
+ /csit/resources/tools/virl/topologies/double-ring-nested.xenial.virl\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 "apt-get update",\r
+"apt-get upgrade" on that day), produced 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 CSIT source repository:\r
+\r
+ resources/tools/disk-image-builder/ubuntu/lists/|virl-image-ubuntu|\r
+\r
+A replica of this VM image can be built by running the "build.sh" script in CSIT\r
+repository resources/tools/disk-image-builder/ubuntu.\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 CSIT source repository:\r
+\r
+ resources/tools/disk-image-builder/ubuntu/lists/|virl-image-centos|\r
+\r
+A replica of this VM image can be built by running the "build.sh" script in CSIT\r
+repository resources/tools/disk-image-builder/centos.\r
+\r
+**#. Nested VM image**\r
+\r
+In addition to the "main" VM image, tests which require VPP to communicate to a\r
+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 as\r
+for the "main" image, scripts to produce an identical replica of the "nested"\r
+image are included in CSIT GIT repository, and the image can be rebuilt using\r
+the "build.sh" script at:\r
+\r
+ resources/tools/disk-image-builder/ubuntu/lists/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 file\r
+\r
+ /csit/resources/tools/virl/topologies/double-ring-nested.xenial.yaml\r
+\r
