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:
::
