12.2. 配置 OVS-DPDK 参数

在 resource_registry 下为 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

在 parameter_defaults 下，将隧道类型设置为 vxlan，并将网络类型设置为 vxlan,vlan ：

NeutronTunnelTypes: 'vxlan'
NeutronNetworkType: 'vxlan,vlan'

在 parameters_defaults 下，设置网桥映射：

# The OVS logical->physical bridge mappings to use.
NeutronBridgeMappings:
  - dpdk-mgmt:br-link0

在 parameter_defaults 下，为 ComputeOvsDpdkSriov 角色设置特定于角色的参数：

  ##########################
  # OVS DPDK configuration #
  ##########################
  ComputeOvsDpdkSriovParameters:
    KernelArgs: "default_hugepagesz=1GB hugepagesz=1G hugepages=32 iommu=pt intel_iommu=on isolcpus=2-19,22-39"
    TunedProfileName: "cpu-partitioning"
    IsolCpusList: "2-19,22-39"
    NovaComputeCpuDedicatedSet: ['4-19,24-39']
    NovaReservedHostMemory: 4096
    OvsDpdkSocketMemory: "3072,1024"
    OvsDpdkMemoryChannels: "4"
    OvsPmdCoreList: "2,22,3,23"
    NovaComputeCpuSharedSet: [0,20,1,21]
    NovaLibvirtRxQueueSize: 1024
    NovaLibvirtTxQueueSize: 1024

为 SR-IOV 配置特定于角色的参数：

  NovaPCIPassthrough:
    - vendor_id: "8086"
      product_id: "1528"
      address: "0000:06:00.0"
      trusted: "true"
      physical_network: "sriov-1"
    - vendor_id: "8086"
      product_id: "1528"
      address: "0000:06:00.1"
      trusted: "true"
      physical_network: "sriov-2"
