sigh, my patch is not correct. the order of the ports is not preserved on
the neutron /ports.json call, and that is important to nova.

Does anyone know a solution to this?

e.g. if i have an instance that has 2 ports, GET
/...ports.json?device_id=UUID might return them in either order, presumably
since its stored as a hashmap or something.
