Test Environment
================
-CSIT functional tests are currently executed in FD.IO VIRL testbed. The physical
-VIRL testbed infrastructure consists of three VIRL hosts:
-
-- All hosts are Cisco UCS C240-M4 (2x Intel(R) Xeon(R) CPU E5-2699 v3 @2.30GHz,
- 18c, 512GB RAM)
+CSIT VPP functional tests are executed in FD.io VIRL testbeds. The

-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 :file:`csit/bootstrap.sh` file. The VIRL host to run
-VIRL simulation is selected based on least load algorithm 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 :file:`/etc/vpp/startup.conf` file,
-in all VIRL simulations.

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.

rebuilt using the "build.sh" script at `VIRL nested`_.
