Dan,

Is there a way to do this on an instance already provisioned and maybe just reboot it to pick up the new ip?

Thanks for the quick reply.

It shows up in quantum port-list as well as quantum net-list and is able to route traffic in and out of my vlan'd network. I have a requirement to assign another fixed IP (not floating) from a new vlan to the same virtual interface on the instance. When I create another subnet in quantum, that works. How do I assign an ip address from the new subnet to the same openvswitch port via quantum?
