+os-nosdn-kvm_ovs_dpdk-noha Description
+==========================================
+
+Introduction
+------------
+
+.. In this section explain the purpose of the scenario and the
+   types of capabilities provided
+
+The purpose of os-nosdn-kvm_ovs_dpdk-noha scenario testing is to test the No
+High Availability deployment and configuration of OPNFV software suite
+with OpenStack and without SDN software. This OPNFV software suite
+includes OPNFV KVM4NFV latest software packages for Linux Kernel and
+QEMU patches for achieving low latency. When deployed using Fuel, No High
+Availability feature is achieved by deploying OpenStack multi-node setup with
+1 controller and 3 computes nodes and using Apex the setup is with 1 controller
+and 1 compute.
+
+KVM4NFV packages will be installed on compute nodes as part of deployment.
+This scenario testcase deployment is happening on multi-node by using OPNFV Fuel
+and Apex deployer.
+
+
+**Using Fuel Installer**
+
+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 No High Availability OPNFV Cloud based on the
+configurations provided in no-ha_nfv-kvm_nfv-ovs-dpdk_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-noha) and an actual deployment
+  scenario configuration file(no-ha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml)
+
+* ``deployment-scenario-metadata:`` Contains the configuration metadata like
+  title,version,created,comment.
+
+.. code:: bash
+
+   deployment-scenario-metadata:
+      title: NFV KVM and OVS-DPDK NOHA deployment
+      version: 0.0.1
+      created: Dec 20 2016
+      comment: NFV KVM and OVS-DPDK
+
+* ``stack-extensions:`` Stack extentions are opnfv added value features in form
+  of a fuel-plugin.Plugins listed in stack extensions are enabled and
+  configured. os-nosdn-kvm_ovs_dpdk-noha scenario currently uses KVM-1.0.0 plugin.
+
+.. code:: bash
+
+   stack-extensions:
+      - module: fuel-plugin-kvm
+        module-config-name: fuel-nfvkvm
+        module-config-version: 1.0.0
+        module-config-override:
+          # Module config overrides
+
+* ``dea-override-config:`` Used to configure the NO-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(``1 controller,3 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
+     - Uses VLAN as an interface
+
+  * **Node 2**:
+     - This node has compute and Ceph-osd roles
+     - Ceph is a massively scalable, open source, distributed storage system
+     - By default, Compute uses KVM as the hypervisor
+     - Uses DPDK as an interface
+
+  * **Node 3**:
+     - This node has compute and Ceph-osd roles
+     - Ceph is a massively scalable, open source, distributed storage system
+     - By default, Compute uses KVM as the hypervisor
+     - Uses DPDK as an interface
+
+  * **Node 4**:
+     - This node has compute and Ceph-osd roles
+     - Ceph is a massively scalable, open source, distributed storage system
+     - By default, Compute uses KVM as the hypervisor
+     - Uses DPDK as an interface
+
+  The below is the ``dea-override-config`` of the no-ha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml file.

+
+* ``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. The no-ha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml
+  has no dha-config changes i.e., default configuration is used.
+
+* os-nosdn-kvm_ovs_dpdk-noha scenario is successful when all the 4 Nodes are accessible,
+  up and running.
+
+
+
+**Note:**
+
+* In os-nosdn-kvm_ovs_dpdk-noha scenario, OVS is installed on the compute nodes with DPDK configured
+
+* Hugepages for DPDK are configured in the attributes_1 section of the
+no-ha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml
+
+* Hugepages are only configured for compute nodes
+
+* This results in faster communication and data transfer among the compute nodes
+
+
+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
+
+* The high availability feature is disabled and deploymet is done by deploy.py with
+  noha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml as an argument.
+* Install Fuel Master and deploy OPNFV Cloud from scratch on Hardware
+  Environment:
+
+
+Command to deploy the os-nosdn-kvm_ovs_dpdk-noha scenario:
+
+.. code:: bash
+
+        $ cd ~/fuel/ci/
+        $ sudo ./deploy.sh -f -b file:///tmp/opnfv-fuel/deploy/config -l devel-pipeline -p default \
+        -s no-ha_nfv-kvm_nfv-ovs-dpdk_heat_ceilometer_scenario.yaml -i file:///tmp/opnfv.iso
+
+where,
+    -b is used to specify the configuration directory
+
+    -i is used to specify the image downloaded from artifacts.
+
+**Note:**
+
+.. code:: bash
+
+         Check $ sudo ./deploy.sh -h for further information.
+
+* os-nosdn-kvm_ovs_dpdk-noha scenario can be executed from the jenkins project
+  "fuel-os-nosdn-kvm_ovs_dpdk-noha-baremetal-daily-master"
+* This scenario provides the No High Availability feature by deploying
+  1 controller,3 compute nodes and checking if all the 4 nodes
+  are accessible(IP,up & running).
+* Test Scenario is passed if deployment is successful and all 4 nodes have
+  accessibility (IP , up & running).
+
+
+**Using Apex Installer**
+
+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 is composed of common OpenStack services enabled by default,
+including Nova, Neutron, Glance, Cinder, Keystone, Horizon.  Optionally and
+by default, Tacker and Congress services are also enabled.  Ceph is used as
+the backend storage to Cinder on all deployed nodes.
+
+The os-nosdn-kvm_ovs_dpdk-noha.yaml file contains following configurations and
+is passed as an argument to deploy.sh script.
+
+* ``global-params:`` Used to define the global parameter and there is only one
+  such parameter exists,i.e, ha_enabled
+
+.. code:: bash
+
+   global-params:

+  tenant networks, whether to run the kvm real time kernel (rt_kvm) in the
+  compute node(s) to reduce the network latencies caused by network function
+  virtualization and whether to install and configure fdio functionality in the
+  overcloud
+
+.. code:: bash
+
+   deploy_options:
+     sdn_controller: false
+     tacker: true
+     congress: true
+     sfc: false
+     vpn: false
+     rt_kvm: true

+.. 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
+
+* The high availability feature can be acheived by executing deploy.sh with
+  os-nosdn-kvm_ovs_dpdk-noha.yaml as an argument.
+
+* Build the undercloud and overcloud images as mentioned below:
+
+.. code:: bash
+
