openvswitch 桥接到kvm

1.定义桥接网络

新建网络配置文件

sudo vi /etc/libvirt/qemu/networks/ovs-br0.xml

<network>

  <name>ovs-br0</name>

  <forward mode='bridge'/>

  <bridge name='ovs-br0'/>

  <virtualport type='openvswitch'/>

</network>

ovs-br0 为openvswitch 的桥名称

2.新建网络

sudo virsh net-define  /etc/libvirt/qemu/networks/ovs-br0.xml

3.启动kvm桥接网络 ovs-br0

virsh net-start ovs-br0

4.设置kvm的桥接网络 ovs-br0 开机自动启动

virsh net-autostart ovs-br0

5.验证新创建的网络配置

$ virsh net-list

Name                State      Autostart    Persistent

----------------------------------------------------------

ovs-br0              active    yes          yes
