When I boot VM with the command below, it should pick up the network in
zone-149

nova boot --flavor 1 --image cirros-0.3.3-x86_64 --availability-zone
zone-149 vm-zone-149

But I got error msg: 
ERROR (Conflict): Multiple possible networks found, use a Network ID to be more specific. (HTTP 409) (Request-ID: req-6b01d821-f8a8-4537-b3d1-bf7aebc86a79)
