Bug description:
  Hi I met a problem when booting VM using dpdkvhostuser port, I'm using
  the ubuntu 16.04 cloud image and boot from openstack.

  Error messages are like following:

  I found that difference between normal ovs VM and dpdk ovs VM is in the network_json, the key 'type' is not the same:
  normal ovs port:
  {
     'services':[

     ],
     'links':[
        {
           'mtu':None,
           'id':'tap7668d181-fb',
           'vif_id':'7668d181-fbce-4e4a-a366-b3dc22dbb831',
           'type':'ovs',
           'ethernet_mac_address':'fa:16:3e:a3:27:27'
        }
     ],
     'networks':[
        {
           'id':'network0',
           'type':'ipv4_dhcp',
           'link':'tap7668d181-fb',
           'network_id':'b42e1ea8-7486-47e0-94df-006bd95edfe5'
        }
     ]
  }

  dpdk vhost port:
  {
     'networks':[
        {
           'id':'network0',
           'network_id':'2173c81e-2799-4645-acff-623fab93e9ec',
           'type':'ipv4_dhcp',
           'link':'tap69061801-e6'
        }
     ],
     'links':[
        {
           'id':'tap69061801-e6',
           'vif_id':'69061801-e6fd-4371-bb4a-8e0b5da21eef',
           'ethernet_mac_address':'fa:16:3e:69:58:84',
           'mtu':None,
           'type':'vhostuser'
        }
     ],
     'services':[

     ]
  }
