            用virt-manager工具创建的虚机不用使用openvswitch bridge, 可以添加“<virtualport type='openvswitch' />”解决。

sudo virsh edit fedora19

    <interface type='bridge'>
      <mac address='52:54:00:c7:13:ec'/>
      <source bridge='br-phy'/>
      <virtualport type='openvswitch' />
      <model type='e1000'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>

以上生成的 是macvtap bridge mode的虚拟网卡。

也可以直接定义一个ovs的network， 如下：

sudo apt-get install qemu-system qemu-kvm virtinst libvirt-bin openvswitch-datapath-source openvswitch-controller openvswitch-switch virt-top virt-manager python-libvirt
sudo ovs-vsctl add-br br-phy
sudo virsh net-destroy default
sudo virsh net-edit default
<network>
  <name>br-phy</name>
  <forward mode='bridge'/>
  <bridge name='br-phy'/>
  <virtualport type='openvswitch'/>
</network>
sudo virsh net-undefine default
sudo irsh net-autostart br-phy
cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto br-phy
iface br-phy inet static
   address 172.16.1.1
   network 172.16.1.0
   netmask 255.255.255.0
   broadcast 172.16.1.255
iface br-phy inet6 static
   address 2001:172:16:1::1
   netmask 64
reboot your machine
