KVM nested OpenStack issues

I have a single large Ubuntu 12.04 server running Essex that I use for a variety of testing. I would like to run OpenStack inside of this OpenStack environment.

The "host" OpenStack server is a single all-in-one installation configured to use VlanManager.

The nested OpenStack environment is one controller node and two compute nodes. VlanManager is also being used.

virtio is used for the NIC driver for everything -- host and nested.

Everything works inside the nested OpenStack environment except I'm running into bridging problems:

Whether I'm trying multi_host or non-multi_host, the virtual NIC of the instance (vnetX) is attached to the bridge on the nested compute node it is hosted on, but other nested compute nodes are unable to see it.

Is there a way to fix this?

Thanks, Joe

It looks like this is possible when the host OpenStack install is using Quantum and the guest OpenStack nodes are using FlatDHCP.
