Dan,
I totally agree that the driver should be thin and focus on VM
provision/termination.
While ii may be looked unimportant, I just prefer that the quantum manager
will determine both VIF and bridge name instead of using a convention that
these names are extracted from the UUID.

Best Regards,
RamiC
