Oh, seems you did not configured rgmanager - there is no 'rm' section in your cluster config?

Try to add an empty config "<rm></rm>"
maybe, by default this should start with "<rm/>"

when i did my test, i had to start rgmanager by hand. (ansible makes it easy to do this to all nodes at the same time)

What happens if the resource does not exist? when i deleted the one HA vm, its entry was still in rm section of HA config. in /var/log/syslog, i saw
Code:

Sep  4 06:51:28 prox1 rgmanager[20704]: [pvevm] VM 101 does not exist
but nothing that looked like more attempts to start this non existant vm. deleting its entry replaced it with "<rm/>" and that seems to keep things happy.
