+Test Environment

+================

+

+CSIT functional tests are currently executed in FD.IO VIRL testbed. The physical

+VIRL testbed infrastructure consists of three identical VIRL hosts:

+

+- All hosts are Cisco UCS C240-M4 (2x Intel(R) Xeon(R) CPU E5-2699 v3 @2.30GHz,

+  18c, 512GB RAM)

+- Hosts run Ubuntu 14.04.3

+- VIRL software versions:

+

+  - STD server version 0.10.24.7

+  - UWM server version 0.10.24.7

+

+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 number of test groups defined by

+TEST_GROUPS variable in csit/bootstrap.sh file. The VIRL host to run VIRL

+simulation is selected randomly per VIRL simulation.

+

+Every VIRL simulation uses the same three-node - Traffic Generator (TG node) and

+two Systems Under Test (SUT1 and SUT2) - "double-ring" topology. The appropriate

+pre-built VPP packages built by Jenkins for the patch under review are then

+installed on the two SUTs, along with their /etc/vpp/startup.conf file, in all

+VIRL simulations.

+

+SUT Configuration - VIRL Guest VM

+---------------------------------

+

+Configuration of the SUT VMs is defined in file

+

+   /csit/resources/tools/virl/topologies/double-ring-nested.xenial.virl

+   

+- 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 Configuration - VIRL Guest OS Linux

+---------------------------------------

+

+In CSIT terminology, the VM operating system for both SUTs that VPP 17.01 has

+been tested with, is the following:

+

+**#. ubuntu-16.04.1_2016-12-19_1.6**

+

+This image implies Ubuntu 16.04.1 LTS, current as of 2016/12/19 (that is,

+package versions are those that would have been installed by a "apt-get update",

+"apt-get upgrade" on December 19), produced by CSIT disk image build scripts

+version 1.6.

+

+The exact list of installed packages and their versions (including the Linux

+kernel package version) are included in CSIT source repository:

+

+  resources/tools/disk-image-builder/ubuntu/lists/ubuntu-16.04.1_2016-12-19_1.6

+

+A replica of this VM image can be built by running the "build.sh" script in CSIT

+repository resources/tools/disk-image-builder/ubuntu.

+

+**#. centos-7.3-1611_2017-01-24_1.2**

+

+The Centos7.3 image is ready to be used but no tests running on it now.

+Corresponding Jenkins jobs are under preparation.

+

+The exact list of installed packages and their versions (including the Linux

+kernel package version) are included in CSIT source repository:

+

+  resources/tools/disk-image-builder/ubuntu/lists/centos-7.3-1611_2017-01-24_1.2

+

+A replica of this VM image can be built by running the "build.sh" script in CSIT

+repository resources/tools/disk-image-builder/centos.

+

+**#. 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:

+

+   resources/tools/disk-image-builder/ubuntu/lists/nested

+

+DUT Configuration - 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 file

+

+   /csit/resources/tools/virl/topologies/double-ring-nested.xenial.yaml

+   

+Example of DUT nodes configuration:::

+

+    DUT1:

+        type: DUT

+TG Configuration

+----------------

+

+Traffic Generator node is VM running the same OS Linux as SUTs. Ports of this

+VM are used as source (Tx) and destination (Rx) ports for the traffic.

+

+Traffic scripts of test cases are executed on this VM.

+

+**TG VM configuration**

+

+Configuration of the TG VMs is defined in file

+

+   /csit/resources/tools/virl/topologies/double-ring-nested.xenial.virl

+**TG node port configuration**

+

+Port configuration of TG is defined in topology file that is generated per VIRL

+simulation based on the definition stored in file

+

+   /csit/resources/tools/virl/topologies/double-ring-nested.xenial.yaml

+

+Example of TG node configuration:::

+

+    TG:
