Title:
  vif-driver of Nova requires Portbindings extension

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  I used Ryu plugin with Nova LibvirtHybridOVSBridgeDriver.
  When I launched an instance, the following problems occurred on nova-compute.

   Traceback (most recent call last):
     File "/opt/stack/nova/nova/compute/manager.py", line 960, in _spawn
       block_device_info)

  It seems the result of Change Ib043e1e6.
    Make Quantum plugin fill in the 'bridge' name
    https://review.openstack.org/#/c/19119/

  nova/network/quantumv2/api.py
      bridge = None
      vif_type = port.get('binding:vif_type')
      # TODO(berrange) Quantum should pass the bridge name
      # in another binding metadata field
      if vif_type == network_model.VIF_TYPE_OVS:
          bridge = CONF.quantum_ovs_bridge
      elif vif_type == network_model.VIF_TYPE_BRIDGE:
          bridge = "brq" + port['network_id']

  By the above, I think that Qauntum plugin used with vif-driver of Nova
  has to support Portbindings extension.
