Oh, no. I use floating IPs for actually "real" public IPs. But now, that you mention the pools, well, I would have to assign one "floating IP" to at least TWO KVM instances.
Hm, Pacemaker/Corosync *inside* the VM will add the Service-IP to the local ethernet interface, and thus, the outside OpenStack components do not know about. Using a dedicated floating IP pool for service IPs might feel like a great solution, but OpenStack is not the one to manage who gets what IP - but Corosync/Pacemaker inside the KVM instances. :-) Anyone an idea how to solve this?
