Foget that, I have resolved it, but another question happened: when I use
ovs-vsctl create ovsbr0,
[root@Mic ovs]# ovs-vsctl show
0a6f41ed-415a-4868-a41a-592145adb1c7
    Bridge "ovsbr0"
        Port "ovsbr0"
            Interface "ovsbr0"
                type: internal

and then I want to use this network by virsh, error happens as below:

[root@Mic ovs]# virsh net-define /etc/libvirt/qemu/networks/ovs_nat.xml
Network ovs_nat defined from /etc/libvirt/qemu/networks/ovs_nat.xml
[root@Mic ovs]# virsh net-create /etc/libvirt/qemu/networks/ovs_nat.xml
error: Failed to create network from /etc/libvirt/qemu/networks/ovs_nat.xml
error: internal error Network is already in use by interface ovsbr0

The content of ovs_nat.xml is:
<!--

    </dhcp>
  </ip>

</network>


Hope your response. Thanks a lot.
