Why not try something like this on your vm?

[root@localhost ~(keystone_admin)]# nova help  interface-attach
usage: nova interface-attach [--port-id ] [--net-id ]
                             [--fixed-ip ]

Attach a network interface to an instance.

Positional arguments:
                Name or ID of server.

Optional arguments:
  --port-id    Port ID.
  --net-id      Network ID
                        Requested fixed IP.
