4.2. NFV 部署支持的配置

流程

1. 修改 containers-prepare-parameter.yaml 文件，使 neutron_driver 参数设置为 ovs。

   parameter_defaults:
     ContainerImagePrepare:
     - push_destination: true
       set:
        neutron_driver: ovs
        ...

2. 将 neutron-ovs.yaml 环境文件包含到 /usr/share/openstack-tripleo-heat-templates/environments/services 目录中。

   TEMPLATES=/usr/share/openstack-tripleo-heat-templates
   
   openstack overcloud deploy --templates \
   -e ${TEMPLATES}/environments/network-environment.yaml \
   -e ${TEMPLATES}/environments/network-isolation.yaml \
   -e ${TEMPLATES}/environments/services/neutron-ovs.yaml \
   -e ${TEMPLATES}/environments/services/neutron-ovs-dpdk.yaml \
   -e ${TEMPLATES}/environments/services/neutron-sriov.yaml \
   -e /home/stack/containers-prepare-parameter.yaml

流程

1. 生成 ComputeOvsDpdkSriov 角色：

   openstack overcloud roles generate -o roles_data.yaml Controller ComputeOvsDpdkSriov

2. 将 OS::TripleO::Services::OVNMetadataAgent 添加到 Controller 角色。

3. 使用 resource_registry 参数为 OVS-DPDK 添加自定义资源：

   resource_registry:
       # Specify the relative/absolute path to the config files you want to use for override the default.
       OS::TripleO::ComputeOvsDpdkSriov::Net::SoftwareConfig:
         nic-configs/computeovsdpdksriov.yaml
       OS::TripleO::Controller::Net::SoftwareConfig:
         nic-configs/controller.yaml

4. 在 parameter_defaults 部分中，将 tunnel type 参数的值编辑为 geneve ：

   NeutronTunnelTypes: 'geneve'
   NeutronNetworkType: ['geneve', 'vlan']

5. 可选：如果您使用集中式路由模型，请禁用分布式虚拟路由(DVR)：

   NeutronEnableDVR: false

6. 在 parameters_defaults 下，设置网桥映射：

    # The OVS logical-to-physical bridge mappings to use.
     NeutronBridgeMappings: "datacentre:br-ex,data1:br-link0,data2:br-link1"

7. 在 computeovsdpdksriov.yaml 文件中配置网络接口：

     - type: ovs_user_bridge
       name: br-link0
       use_dhcp: false
       ovs_extra:
        - str_replace:
          template: set port br-link0 tag=_VLAN_TAG_
          params:
           _VLAN_TAG_:
            get_param: TenantNetworkVlanID
       addresses:
        - ip_netmask:
          get_param: TenantIpSubnet
       members:
       - type: ovs_dpdk_port
         name: br-link0-dpdk-port0
         rx_queue: 1
         members:
         - type: interface
           name: eno3
     - type: sriov_pf
       name: eno4
       use_dhcp: false
       numvfs: 5
       defroute: false
       nm_controlled: true
       hotplug: true
       promisc: false

8. 在部署脚本中包含以下 yaml 文件：

   • neutron-ovn-dpdk.yaml
   • neutron-ovn-sriov.yaml

流程

1. 生成 ComputeOvsDpdkSriov 角色：

   openstack overcloud roles generate -o roles_data.yaml \
   ControllerSriov ComputeSriov

2. 配置与部署相关的 physical_network 参数设置。

   • 对于 VLAN，将 physical_network 参数设置为部署后您在 neutron 中创建的网络的名称。还对 NeutronBridgeMappings 参数使用这个值。

   • 在特定于角色的参数下，如 ComputeSriovOffloadParameters，确保 OvsHwOffload 参数的值为 true。

     parameter_defaults:
       NeutronBridgeMappings: 'datacentre:br-ex,tenant:br-offload'
       NeutronNetworkVLANRanges: 'tenant:502:505'
       NeutronFlatNetworks: 'datacentre,tenant'
       NeutronPhysicalDevMappings:
         - tenant:ens1f0
         - tenant:ens1f1
     
       NovaPCIPassthrough:
       - address: "0000:17:00.1"
         physical_network: "tenant"
       - address: "0000:3b:00.1"
         physical_network: "tenant"
       NeutronTunnelTypes: ''
       NeutronNetworkType: 'vlan'
       ComputeSriovOffloadParameters:
         OvsHwOffload: True
         KernelArgs: "default_hugepagesz=1GB hugepagesz=1G hugepages=32 intel_iommu=on iommu=pt isolcpus=1-11,13-23"
         IsolCpusList: "1-11,13-23"
         NovaReservedHostMemory: 4096
         NovaComputeCpuDedicatedSet: ['1-11','13-23']
         NovaComputeCpuSharedSet: ['0','12']

3. 在 computeovsdpdksriov.yaml 文件中配置网络接口：

    - type: ovs_bridge
     name: br-offload
     mtu: 9000
     use_dhcp: false
     addresses:
     - ip_netmask:
        get_param: TenantIpSubnet
     members:
     - type: linux_bond
       name: bond-pf
       bonding_options: "mode=active-backup miimon=100"
       members:
       - type: sriov_pf
         name: ens1f0
         numvfs: 3
         primary: true
         promisc: true
         use_dhcp: false
         defroute: false
         link_mode: switchdev
       - type: sriov_pf
         name: ens1f1
         numvfs: 3
         promisc: true
         use_dhcp: false
         defroute: false
         link_mode: switchdev

4. 在部署脚本中包含以下 yaml 文件：

   • ovs-hw-offload.yaml

   • neutron-ovn-sriov.yaml

      TEMPLATES_HOME=”/usr/share/openstack-tripleo-heat-templates”
         CUSTOM_TEMPLATES=”/home/stack/templates”
     
         openstack overcloud deploy --templates \
           -r ${CUSTOM_TEMPLATES}/roles_data.yaml \
           -e ${TEMPLATES_HOME}/environments/services/neutron-ovn-sriov.yaml \
           -e ${TEMPLATES_HOME}/environments/ovs-hw-offload.yaml \
           -e ${CUSTOM_TEMPLATES}/network-environment.yaml
