Open Stack

Hi Eric, 
I would use packstack it works really well for what you need to do. Any reasons why you want Nova Network vs Neutron?

The only thing you need is make sure your two nics are up and running.

There are indications that some nics should have no IP address assigned but rather be part of a bridge which has the IP address, but the docs are vague about that and different architectures seem to need different configs.
