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. No High Availability feature is achieved +by deploying OpenStack multi-node setup with 1 controller and 3 computes nodes. + +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 deployer. + +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. + +.. code:: bash + + dea-override-config: + fuel: + FEATURE_GROUPS: + - experimental + environment: + net_segment_type: vlan + nodes: + - id: 1 + interfaces: interfaces_vlan + role: mongo,controller + - id: 2 + interfaces: interfaces_dpdk + role: ceph-osd,compute + attributes: attributes_1 + - id: 3 + interfaces: interfaces_dpdk + role: ceph-osd,compute + attributes: attributes_1 + - id: 4 + interfaces: interfaces_dpdk + role: ceph-osd,compute + attributes: attributes_1 + + attributes_1: + hugepages: + dpdk: + value: 1024 + nova: + value: + '2048': 1024 + + network: + networking_parameters: + segmentation_type: vlan + networks: + - cidr: null + gateway: null + ip_ranges: [] + meta: + configurable: false + map_priority: 2 + name: private + neutron_vlan_range: true + notation: null + render_addr_mask: null + render_type: null + seg_type: vlan + use_gateway: false + vlan_start: null + name: private + vlan_start: null + + settings: + editable: + storage: + ephemeral_ceph: + description: Configures Nova to store ephemeral volumes in RBD.
