KVM上のVMに対してOpen vSwitchのインタフェースをアタッチする

環境

  • KVMのホスト名 kvm02

  • VMsrv

  • Open vSwitch構成情報

[root@kvm02]ovs-vsctl show
0f695921-8a70-46a5-a588-a47240e431da
    Bridge ovs-pub
        Port "vnet2"
            Interface "vnet2"
        Port "enp7s0f1"
            Interface "enp7s0f1"
        Port ovs-pub
            Interface ovs-pub
                type: internal
    Bridge ovs-mng
        Port "vnet1"
            Interface "vnet1"
        Port "enp2s0f0"
            Interface "enp2s0f0"
        Port ovs-mng
            Interface ovs-mng
                type: internal
    Bridge ovs-dummy
        Port ovs-dummy
            Interface ovs-dummy
                type: internal
        Port "vnet3"
            Interface "vnet3"
    Bridge ovs-fuel
        Port "enp2s0f1"
            Interface "enp2s0f1"
        Port "vnet0"
            Interface "vnet0"
        Port ovs-fuel
            Interface ovs-fuel
                type: internal
    ovs_version: "2.3.1"
  • VMxmlファイル Interface部分抜粋(変更前)
    <interface type='network'>
      <mac address='52:54:00:60:db:b8'/>
      <source network='ovs-dummy'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>

手順

  1. VMのコンソールに接続してログイン
virsh console srv
  1. NICの再構成をする為、定義ファイルを削除
rm /etc/udev/rules.d/70-persistent-net.rules
  1. 該当VMを停止
shutdown -h now

4.XMLファイルを編集

virsh edit srv

以下のようにxmlを編集

    <interface type='bridge'>
      <mac address='52:54:00:60:db:b8'/>
      <source bridge='ovs-pub'/>
      <virtualport type='openvswitch'>
        <parameters interfaceid='75c7de80-3c5c-4c97-8739-84113ae2fbba'/>
      </virtualport>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>
    <interface type='bridge'>
      <mac address='52:54:00:50:ca:11'/>
      <source bridge='ovs-mng'/>
      <virtualport type='openvswitch'>
        <parameters interfaceid='544b6771-04d9-46fc-8822-dbd878a3efca'/>
      </virtualport>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </interface>
  1. VMを起動
virsh start srv
  1. VMのコンソールに接続して状態を確認する
virsh console srv
