[CentOS] High Availability questions

I'm trying to set up a small cluster using the High Availability and 
High Availability Management groups. I'd like to run this on 3 different 
machines, one being a "management" machine and the other two being the 
actual cluster. It doesn't seem to want to cooperate. I can set the 
cluster nodes up just fine, working from the management server. As soon 
as I try adding an "IP address" to the cluster, everything goes south. I 
can no longer use luci on any of the three machines.

I can start luci on any of the 3 servers, but the cluster doesn't show 
any more. If I try and recreate the cluster, it indicates the cluster 
already exists. I can't find anything in the logs other than a bunch of 
python errors similar to perl errors, and those don't really seem to be 
indicative of hard errors.

I've got this scheme running successfully on 3 virtual machines on a 
single host, and that seems to work just fine. Real servers are beating 
me up.

Any suggestions, please?
