+===================================
+
+This document provides scenario level details for Danube of Barometer.

+
+Introduction
+---------------
+.. In this section explain the purpose of the scenario and the types of
+.. capabilities provided
+This scenario combines the features from the following three projects in a
+single instantiation of OPNFV:
+
+- KVM4NFV
+- OVS4NFV
+- Barometer
+
+A distinguishing factor for this scenario vs other scenarios that integrate
+Open vSwitch and KVM is that collectd (a telemetry agent) is installed on
+compute nodes so that their statistics and events can be relayed to ceilometer.
+These are the first steps in paving the way for Platform (NFVI) Monitoring in
+OPNFV.
+
+For Fuel this scenario installs the latest DPDK-enabled Open vSwitch component,
+KVM4NFV latest software packages for Linux Kernel and QEMU patches for
+achieving low latency, and the collectd telemetry agent.
+
+Scenario components and composition
+-------------------------------------
+.. In this section describe the unique components that make up the scenario,
+.. what each component provides and why it has been included in order
+.. to communicate to the user the capabilities available in this scenario.
+
+This scenario deploys the High Availability OPNFV Cloud based on the
+configurations provided in ha_nfv-kvm_ovs_bar_heat_ceilometer_scenario.yaml.
+This yaml file contains following configurations and is passed as an
+argument to deploy.py script
+
+* scenario.yaml:This configuration file defines translation between a
+ short deployment scenario name(os-nosdn-kvm_ovs_dpdk_bar-ha) and an actual
+ deployment scenario configuration file
+ (ha_nfv-kvm_nfv-ovs-dpdk_bar_heat_ceilometer_scenario.yaml)
+
+* deployment-scenario-metadata:Contains the configuration metadata like
+ title,version,created,comment.
+
+* stack-extensions:Stack extentions are opnfv added value features in form
+ of a fuel-plugin.Plugins listed in stack extensions are enabled and
+ configured.
+
+* dea-override-config: Used to configure the HA mode,network segmentation
+ types and role to node assignments. These configurations overrides
+ corresponding keys in the dea_base.yaml and dea_pod_override.yaml.
+ These keys are used to deploy multiple nodes(3 controllers,2 computes)
+ as mention below.
+
+* **Node 1**: This node has MongoDB and Controller roles. The controller
+ node runs the Identity service, Image Service, management portions of
+ Compute and Networking, Networking plug-in and the dashboard. The
+ Telemetry service which was designed to support billing systems for
+ OpenStack cloud resources uses a NoSQL database to store information.
+ The database typically runs on the controller node.
+
+* **Node 2**: This node has Controller and Ceph-osd roles. Ceph is a
+ massively scalable, open source, distributed storage system. It is
+ comprised of an object store, block store and a POSIX-compliant distributed
+ file system. Enabling Ceph, configures Nova to store ephemeral volumes in
+ RBD, configures Glance to use the Ceph RBD backend to store images,
+ configures Cinder to store volumes in Ceph RBD images and configures the
+ default number of object replicas in Ceph.
+
+* **Node 3**: This node has Controller role in order to achieve high
+ availability.
+
+* **Node 4**: This node has Compute role. The compute node runs the
+ hypervisor portion of Compute that operates tenant virtual machines
+ instances. By default, Compute uses KVM as the hypervisor. Collectd
+ will be installed on this node.
+
+* **Node 5**: This node has compute role.
+
+* dha-override-config:Provides information about the VM definition and
+ Network config for virtual deployment. These configurations overrides
+ the pod dha definition and points to the controller,compute and
+ fuel definition files.
+
+* os-nosdn-kvm_ovs_dpdk_bar-ha scenario is successful when all the 5 Nodes are
+ accessible, up and running.
+
+Scenario usage overview
+----------------------------
+.. Provide a brief overview on how to use the scenario and the features available to the
+.. user. This should be an "introduction" to the userguide document, and explicitly link to it,
+.. where the specifics of the features are covered including examples and API's
+
+After installation use of the scenario traffic on the private network will
+automatically be processed by the upgraded DPDK datapath.
+
+Limitations, Issues and Workarounds
+---------------------------------------
+.. Explain scenario limitations here, this should be at a design level rather than discussing
+.. faults or bugs. If the system design only provide some expected functionality then provide
+.. some insight at this point.
