In the current state of the spec I try to keep this case out of scope 
[1]. Having QoS policy requires a special port or network and nova 
server create with network_id only expected to work is simple network 
and port setup. If the user want some special port (like SRIOV) she has 
to pre-create that port in neutron anyhow.
