How do you do STONITH in openvz? I hope you are doing it, because
thats the only thing that prevents corruption in the split brain
situations, now that you've turned off locking (i.e. fencing).

That being said, I'm still struggling to figure out how to do proper
clusters in the virtualized environment. If someone has any
pointers/tutorials/etc I would appreciate it. I'm specifically
interested in situations where you have more than one virtualized
clusters running on the same group of physical nodes.
