   1 Test Environment
   2 ================
   3
   4 CSIT VPP functional tests are executed in FD.io VIRL testbeds. The
   5 physical VIRL testbed infrastructure consists of three VIRL servers:
   6
   7 - tb4-virl1:
   8
   9   - Status: Production
  10   - OS: Ubuntu 16.04.2
  11   - VIRL STD server version: 0.10.32.16
  12   - VIRL UWM server version: 0.10.32.16
  13
  14 - tb4-virl2:
  15
  16   - Status: Production
  17   - OS: Ubuntu 16.04.2
  18   - VIRL STD server version: 0.10.32.16
  19   - VIRL UWM server version: 0.10.32.16
  20
  21 - tb4-virl3:
  22
  23   - Status: Production
  24   - OS: Ubuntu 16.04.2
  25   - VIRL STD server version: 0.10.32.19
  26   - VIRL UWM server version: 0.10.32.19
  27
  28 - VIRL hosts: Cisco UCS C240-M4, each with 2x Intel Xeon E5-2699
  29   v3 (2.30 GHz, 18c), 512GB RAM.
  30
  31 Whenever a patch is submitted to gerrit for review, parallel VIRL
  32 simulations are started to reduce the time of execution of all
  33 functional tests. The number of parallel VIRL simulations is equal to a
  34 number of test groups defined by TEST_GROUPS variable in
  35 :file:`csit/bootstrap.sh` file. VIRL host to run VIRL simulation is
  36 selected based on least load algorithm per VIRL simulation.
  37
  38 Every VIRL simulation uses the same three-node logical ring topology -
  39 Traffic Generator (TG node) and two Systems Under Test (SUT1 and SUT2).
  40 The appropriate pre-built VPP packages built by Jenkins for the patch
  41 under review are then installed on the two SUTs, along with their
  42 :file:`/etc/vpp/startup.conf` file, in all VIRL simulations.
  43
  44 SUT Settings - VIRL Guest VM
  45 ----------------------------
  46
  47 SUT VMs' settings are defined in `VIRL topologies directory`_
  48
  49 - List of SUT VM interfaces:
  50
  51     <interface id="0" name="GigabitEthernet0/4/0"/>
  52     <interface id="1" name="GigabitEthernet0/5/0"/>
  53     <interface id="2" name="GigabitEthernet0/6/0"/>
  54     <interface id="3" name="GigabitEthernet0/7/0"/>
  55
  56 - Number of 2MB hugepages: 1024.
  57
  58 - Maximum number of memory map areas: 20000.
  59
  60 - Kernel Shared Memory Max: 2147483648 (vm.nr_hugepages * 2 * 1024 * 1024).
  61
  62 SUT Settings - VIRL Guest OS Linux
  63 ----------------------------------
  64
  65 In CSIT terminology, the VM operating system for both SUTs that |vpp-release|
  66 has been tested with, is the following:
  67
  68 #. Ubuntu VIRL image
  69
  70    This image implies Ubuntu 16.04.1 LTS, current as of yyyy-mm-dd (that is,
  71    package versions are those that would have been installed by a
  72    :command:`apt-get update`, :command:`apt-get upgrade` on that day), produced
  73    by CSIT disk image build scripts.
  74
  75    The exact list of installed packages and their versions (including the Linux
  76    kernel package version) are included in `VIRL ubuntu images lists`_.
  77
  78    A replica of this VM image can be built by running the :command:`build.sh`
  79    script in CSIT repository.
  80
  81 #. CentOS VIRL image
  82
  83    This image implies Centos 7.4-1711, current as of yyyy-mm-dd (that is,
  84    package versions are those that would have been installed by a
  85    :command:`yum update`, :command:`yum upgrade` on that day), produced
  86    by CSIT disk image build scripts.
  87
  88    The exact list of installed packages and their versions (including the Linux
  89    kernel package version) are included in `VIRL centos images lists`_.
  90
  91    A replica of this VM image can be built by running the :command:`build.sh`
  92    script in CSIT repository.
  93
  94 #. Nested VM image
  95
  96    In addition to the "main" VM image, tests which require VPP to communicate to
  97    a VM over a vhost-user interface, utilize a "nested" VM image.
  98
  99    This "nested" VM is dynamically created and destroyed as part of a test case,
 100    and therefore the "nested" VM image is optimized to be small, lightweight and
 101    have a short boot time. The "nested" VM image is not built around any
 102    established Linux distribution, but is based on `BuildRoot
 103    <https://buildroot.org/>`_, a tool for building embedded Linux systems. Just
 104    as for the "main" image, scripts to produce an identical replica of the
 105    "nested" image are included in CSIT GIT repository, and the image can be
 106    rebuilt using the "build.sh" script at `VIRL nested`_.
 107
 108 DUT Settings - VPP
 109 ------------------
 110
 111 Every System Under Test runs VPP SW application in Linux user-mode as a Device
 112 Under Test (DUT) node.
 113
 114 DUT Port Configuration
 115 ~~~~~~~~~~~~~~~~~~~~~~
 116
 117 Port configuration of DUTs is defined in topology file that is generated per
 118 VIRL simulation based on the definition stored in `VIRL topologies directory`_.
