+DevStack installation
+#####################
+
+Use official `Devstack <https://docs.openstack.org/devstack/pike/>`_
+documentation to install OpenStack on a host. Please note, that stable
+``pike`` branch of devstack repo should be used during the installation.
+The required `local.conf`` configuration file are described below.
+
+DevStack configuration file:
+
+.. note:: Update the devstack configuration file by replacing angluar brackets
+  with a short description inside.
+
+.. note:: Use ``lspci | grep Ether`` & ``lspci -n | grep <PCI ADDRESS>``
+  commands to get device and vendor id of the virtual function (VF).

+TG host configuration
+#####################
+
+Yardstick automatically install and configure Trex traffic generator on TG
+host based on provided POD file (see below). Anyway, it's recommended to check
+the compatibility of the installed NIC on the TG server with software Trex using
+the manual at https://trex-tgn.cisco.com/trex/doc/trex_manual.html.
+
+
+Run the Sample VNF test case
+############################
+
+There is an example of Sample VNF test case ready to be executed in an
+OpenStack environment with SR-IOV support: ``samples/vnf_samples/nsut/vfw/
+tc_heat_sriov_external_rfc2544_ipv4_1rule_1flow_64B_trex.yaml``.
+
+Install yardstick using `Install Yardstick (NSB Testing)`_ steps for OpenStack
+context.
+
+Create pod file for TG in the yardstick repo folder located in the yardstick
+container:
+
+.. note:: The ``ip``, ``user``, ``password`` and ``vpci`` fields show be  changed
+  according to HW environment used for the testing. Use ``lshw -c network -businfo``
+  command to get the PF PCI address for ``vpci`` field.
+
+.. literalinclude:: code/single-yardstick-pod.conf

+Run the Sample vFW RFC2544 SR-IOV TC (``samples/vnf_samples/nsut/vfw/
+tc_heat_sriov_external_rfc2544_ipv4_1rule_1flow_64B_trex.yaml``) in the heat
+context using steps described in `NS testing - using yardstick CLI`_ section.
