编辑下面文件保存成net81.xml

<network>
  <name>net81</name>
  <bridge name='net81' stp='on' delay='0' />
</network>

应用设定并启动

virsh net-define net81.xml
virsh net-start net81

使用ifconfig查看配置好的网卡

net81     Link encap:Ethernet  HWaddr 52:54:00:84:92:2E  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

配置VLAN ID

    <interface type='bridge'>
      <source bridge='br2'/>
      <vlan>
        <tag id='304'/>
      </vlan>
      <virtualport type='openvswitch'>
      </virtualport>
      <model type='virtio'/>
    </interface>
