+T-Rex in VM TestCases
+^^^^^^^^^^^^^^^^^^^^^
+
+A set of functional testcases, which use T-Rex running in VM as a traffic generator.
+These testcases require a VM image with T-Rex server installed. An example of such
+image is a vloop-vnf image with T-Rex available for download at:
+
+http://artifacts.opnfv.org/vswitchperf/vnf/vloop-vnf-ubuntu-16.04_trex_20180209.qcow2
+
+This image can be used for both T-Rex VM and loopback VM in ``vm2vm`` testcases.
+
+**NOTE:** The performance of T-Rex running inside the VM is lower if compared to T-Rex
+execution on bare-metal. The user should perform a calibration of the VM maximum FPS
+capability, to ensure this limitation is understood.
