Indeed, I'm aware of all that. The thing I was enquiring about is the
part that integrates with heartbeat. Heartbeat will happily migrate the
IPs from one host to the other, but it won't do the
naddress --add --nid <guestname> --ip <guestip>
part. I was just wondering if there was a pre-cooked resource management
script for heartbeat that handles this already.
