Hello,

I was using libvirt/qemu-kvm (with pacemaker for high availability) for my virtualisation needs until now. I had a very simple network setup, namely a dumb bridge that did nothing but bridge the interface:

<network>
  <name>default</name>
  <uuid>841ca834-212b-0fa7-c081-6f0cdb1871a6</uuid>
  <forward mode='bridge'/>
  <bridge name='br0' />
</network>

DHCP, VLANs and the firewall are all handled externally, so doing that stuff again would be redundant. What's the easiest way to get a setup like this with openstack?
