Hi Darragh,
Thanks for the detailed write-up. Would be great if you could take this
content and create a bug on launchpad. We'll look into this.
On a related note. The check in stack.sh to avoid creating a floating IP
pool if quantum is enabled is no longer valid, now that Quantum Manager
does (or at least intends to :P ) support floating IPs. But rather than
remove it, it may be good to just change to the check to avoid creating
floating IPs if melange is enabled, as Quantum Manager's current floating
IP support requires using the traditional Nova IPAM, not Melange.
