为隔离的网络创建 control-plane Linux 绑定。

  - type: linux_bond
    name: bond_api
    bonding_options: "mode=active-backup"
    use_dhcp: false
    dns_servers:
      get_param: DnsServers
    members:
    - type: interface
      name: nic3
      primary: true
    - type: interface
      name: nic4

将 VLAN 分配给此 Linux 绑定。

  - type: vlan
    vlan_id:
      get_param: InternalApiNetworkVlanID
    device: bond_api
    addresses:
    - ip_netmask:
        get_param: InternalApiIpSubnet

  - type: vlan
    vlan_id:
      get_param: StorageNetworkVlanID
    device: bond_api
    addresses:
    - ip_netmask:
        get_param: StorageIpSubnet

设置带有 DPDK 端口的网桥，以链接到控制器。

  - 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_bond
        name: dpdkbond0
        mtu: 9000
        rx_queue: 2
        members:
          - type: ovs_dpdk_port
            name: dpdk0
            members:
              - type: interface
                name: nic7
          - type: ovs_dpdk_port
            name: dpdk1
            members:
