I've cross-listed the bug in the quantum project as well so we can track it. The fact that LinuxOVSInterfaceDriver doesn't do anything on unplug is not actually the problem (though its something we should clean up anyway, as there will be stale linux devices lying around...). I believe the real issue is that QuantumManager needs to clean up the "gateway" port on a Quantum network before attempting to delete it, otherwise Quantum refuses to to delete the network with a NetworkInUse error. This should be a QuantumManager fix.
