+********************************
+OPNFV VSPERF with OPNFV Xtesting
+********************************
+
+============
+Introduction
+============
+User can use VSPERF with Xtesting for two different usecases.
+
+1. Baremetal Dataplane Testing/Benchmarking.
+2. Openstack Dataplane Testing/Benchmarking.
+
+The Baremetal usecase is the legacy usecase of OPNFV VSPERF.
+
+The below figure summarizes both the usecases.

+
+===========
+How to Use?
+===========
+
+Step-1: Build the container
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Go the xtesting/baremetal or xtesting/openstack and run the following command.
+
+.. code-block:: console
+
+  docker build -t 127.0.0.1:5000/vsperfbm
+
+
+Step-2: Install and run Xtesting Playbook
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These commands are described in OPNFV Xtesting Documentation. Please refere to OPNFV Xtesting wiki for description of these commands.
+
+.. code-block:: console
+
+  virtualenv xtesting
+  . xtesting/bin/activate
+  ansible-galaxy install collivier.xtesting
+  ansible-playbook site.yml
+
+======================
+Accessing the Results?
+======================
+
+VSPERF automatically publishes the results to any OPNFV Testapi deployment.
+User has to configure following two parameters in VSPERF.
+
+1. OPNFVPOD - The name of the pod.
+2. OPNFV_URL - The endpoint serving testapi.
+
+As Xtesting runs its own testapi, user should point to this (testapi endpoint of Xtesting) using the above two configuration.
+
+The above two configurations should be done wherever VSPERF is running (refer to the figure above)
+
+NOTE: Before running the test, it would help if user can prepre the testapi of Xtesting (if needed). The preparation include setting up the following:
+
+1. Projects
+2. Testcases.
+3. Pods.
+
+Please refer to the documentation of testapi for more details.
+
+=======================================
+Accessing other components of Xtesting?
+=======================================
+
+Please refer to the documentation of Xtesting in OPNFV Wiki.
+
+===========
+Limitations
+===========
+For Jerma Release, following limitations apply:
+
+1. For both baremetal and openstack, only phy2phy_tput testcase is supported.
+2. For openstack, only Spirent's STCv and Keysight's Ixnet-Virtual is supported.
