[Openstack] [Quantum] Need suggestion on networking

Hi,

I did Openstack(Folsom+Quantum) setup, with one controller node ( also
running networking services) and 8 compute nodes. Both controller node and
compute nodes have 2 NIC each, one on public network (internet) and one on
private network.

My requirement is that for each tenant, every VM should be connected to
private network as well as it should also have public IP address, so that
user can directly access that machine over internet. I might add some more
compute node as well, and my VM counts can grow in range of 200-300+. You
can assume that we do have these many public IP's available.

My plan is to create vlan based private network for each tenant, but i am
confused on the public network part of it. Shell i use provider network or
use router/floating ip based networking. I want to user openvswtich (vlan)
plugin for networking.Any suggestions?

Thanks
Anil
