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 +------------------------------------ +..
