+Scenario: "OpenStack - ovs-nfv"
+=============================
+
+Scenario: apex-os-nosdn-ovs-ha
+
+"apex-os-ovs-ha" is a scenario developed as part of the OVS for NFV
+OPNFV project. The main components of the "apex-os-nosdn-ovs-ha" scenario
+are:
+
+ - APEX (TripleO) installer (please also see APEX installer documentation)
+ - Openstack (in HA configuration)
+ - OVS/DPDK Open vSwitch with DPDK data plane virtual forwarder for tenant networking
+
+Introduction
+============
+
+NFV and virtualized high performance applications, such as video processing,
+require Open vSwitch to be accelerated with a fast data plane solution that provides both
+carrier grade forwarding performance, scalability and open extensibility.
+
+A key component of any NFV solution is the virtual forwarder, which should consist of
+soft switch that includes an accelerated data plane component. For this, any virtual
+switch should make use of
+hardware accelerators and optimized cache operation to be run in user space.
+
+The "Openstack - Open vSwitch/DPDK" scenario provides
+use-cases for deployment of NFV nodes instantiated by
+an Openstack orchestration system on OVS/DPDK enabled compute nodes.
+
+A deployment of the "apex-os-nosdn-ovs-ha" scenario consists of 3 or more
+servers:
+
+ * 1 Jumphost hosting the APEX installer - running the Undercloud
+ * 1 Controlhost, which runs the Overcloud and Openstack services
+ * 1 or more Computehosts or nodes
+

+
+Tenant networking leverages Open vSwitch accelerated with a fast user space data path such
+as DPDK.
+Open VSwitch (OVS) with the Linux kernel module data path is used for all other
+connectivity, such as connectivity to public networking "the
+Internet" (i.e. br-ex) is performed via non-accelerated OVS.
+
+Features of the scenario
+------------------------
+
+Main features of the "apex-os-ovs-nosdn-ha" scenario:
+
+ * Automated installation using the APEX installer
+ * Accelerated tenant networking using OVS/DPDK as the forwarder
+
+Networking in this scenario using OVS with accelerated User space IO.
+---------------------------------------------------------------------
+
+The apex-os-nosdn-ovs-ha scenario combines components from three open
+source projects: OpenStack, Open vSwitch and DPDK. To make accelerated networking
+available for this scenario Open vSwitch is bound via its netdev interface
+with DPDK user space accelerated capability.
+
+Scenario Configuration
+======================
+
+Simply deploy this scenario by using the os-ovs-nosdn-ha.yaml deploy
+settings file.
+
+Validated deployment environments
+=================================
+
+The "os-odl_l2-ovs-ha" scenario has been deployed and tested
+on the following sets of hardware:
+ * virtual deployments
+ * Not yet validated on UCS hardware.
+
+
+Limitations, Issues and Workarounds
+===================================
+
+* _APEX-415 br-phy dpdk interfaces are not brought up by os-net-config
