Comment 2 for bug 1820378

We added our own vhostuser port to br-int and use virsh command and cirros-dpdk-vhostuserclient.xml to create VM. The manually created vhostuser port can work.

1. Create vhostuser port:
   ovs-vsctl add-port br-int vhost-user-1 -- set Interface vhost-user-1 type=dpdkvhostuserclient
      options:vhost-server-path=/var/run/openvswitch/vhost-user-1
2. Download image on controller-0 and scp image to compute-0
   wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
   scp cirros-0.3.4-x86_64-disk.img wrsroot@compute-0:~/
3. Copy image to directory /var/lib/nova/instances for creating VM
   cp cirros-0.3.4-x86_64-disk.img /var/lib/nova/instances/
4. Bring up br-int to verify the connectivity:
   sudo ifconfig br-int 192.168.101.1/24 up
2. Create VM:
   virsh create cirros-dpdk-vhostuserclient.xml
4. Manually assign an IP to VM:
   sudo ifconfig eth0 192.168.101.18/24 up
5. In created VM, ping br-int:
   ping 192.168.101.1

The ping succeeds.
