I noticed in the Grizzly Summit session notes for "Closing quantum/nova gaps" there are a couple of overlapping IP items: - metadata service did not support overlapping IPs - nova security groups couldn't handle overlapping IPs (this is being handled by security groups in Quantum, but we still need someone to do the work for iptables based security groups). Is anyone looking into those yet? Or have a plan on what needs to be done? Anything I can help with? Actually, I did just find these two bugs: https://bugs.launchpad.net/quantum/+bug/1038098 https://bugs.launchpad.net/nova/+bug/1053819 Thanks, -Brian
