Comment 21 for bug 2047593

Yes, the environment is quite limited for now. Given the constrains maybe I can use vlans only for internal traffic and not for getting outside the perimeter. E.g. mgmt and storage networks basically. I understand that vxlan would still allow me to give floating IPs to VMs (?) which is good enough for me.

I'm unsure still though of the config for this: "And then likely you in fact need br-ext as an OVS bridge with IP/default route on it, and use it as a flat network, which is not shared (so usable only for floating IPs)."
