+os-nosdn-openo-ha Description
+===========================
+
+Introduction
+------------
+
+Since OPNFV board expanded its scope to include NFV MANO last year,
+several upstream open source projects have been created to develop
+MANO solutions. Each solution has demonstrated its unique value in
+specific area. Open-Orchestrator (OPEN-O) project is one of such
+communities. Opera seeks to develop requirements for OPEN-O MANO
+support in the OPNFV reference platform, with the plan to eventually
+integrate OPEN-O in OPNFV as a non-exclusive upstream MANO. The
+project will definitely benefit not only OPNFV and Open-O, but can
+be referenced by other MANO integration as well. In particular, this
+project is basically use case driven. Based on that, it will focus
+on the requirement of interfaces/data models for integration among
+various components and OPNFV platform. The requirement is designed
+to support integration among Open-O as NFVO with Juju as VNFM and
+OpenStack as VIM.
+
+Currently OPNFV has already included upstream OpenStack as VIM, and
+Juju and Tacker have been being considered as gVNFM by different OPNFV
+projects. OPEN-O as NFVO part of MANO will interact with OpenStack and
+Juju. The key items required for the integration can be described as
+follows.
+
+Scenario Components and Composition
+-----------------------------------
+
+This Scenario will deploy Open-O on jump host as orchestrator and deploy
+juju in an OpenStack VM as VNFM. All Open-O service can be access through
+openo_ip specified in network config file.
+
+Scenario Usage Overview
+-----------------------
+
+This scenario has an orchestrator field to specify which orchestrator to
+be used.
+
+COMPASS installer configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The os-nosdn-openo-ha scenario in Compass4NFV has an orchestrator field.
+Set orchestrator type to Open-O to install Open-O after Compass4NFV finishs
+NFVI deployment and Open-O version can also be assigned in key version.
+With orchestrator setting to Open-O, Compass4NFV will git clone Opera
+project to perform a combined deployment. Set key vnf to clearwater if you
+want to launch clearwater after Open-O launched.
+
+os-nosdn-openo-ha scenario needs to be deployed along with Open-O included
+network config file. Compass4NFV has network_openo.yml to config network for
+Opera.
+
+The Open-O related info in both scenario and network config will be synchronized
+into Opera after its repository being cloned.
