Right now, PackStack only supports Nova Networking.  We will eventually
have support for Quantum in PackStack, but that support is not completed
yet.

So if you specifically need to use Quantum, you would need to:
* Use PackStack to install w/ Nova Networking
* Manually convert from Nova Networking to Quantum

Gary (cc'd) has a draft process for this, but it is still a little shaky.

Gary can you share that process?  Perhaps Shixiong can try it out and
give us feedback on whether it works for him or not.

I don't think so, but Derek would need to confirm.  I think this would
be a feature enhancement.
