+Selection of loopback application for PVP and PVVP tests
+--------------------------------------------------------
+To select loopback application, which will perform traffic forwarding
+inside VM, following configuration parameter should be configured:
+
+ .. code-block:: console
+
+ GUEST_LOOPBACK = ['testpmd', 'testpmd']
+
+ or use --test-param
+
+ ./vsperf --conf-file user_settings.py
+ --test-param "guest_loopback=testpmd"
+
+Supported loopback applications are:
+
+ .. code-block:: console
+
+ 'testpmd' - testpmd from dpdk will be built and used
+ 'l2fwd' - l2fwd module provided by Huawei will be built and used
+ 'linux_bridge' - linux bridge will be configured
+ 'buildin' - nothing will be configured by vsperf; VM image must
+ ensure traffic forwarding between its interfaces
+
+Guest loopback application must be configured, otherwise traffic
+will not be forwarded by VM and testcases with PVP and PVVP deployments
+will fail. Guest loopback application is set to 'testpmd' by default.
