From my very limited experience:
Kvm guests controlled by ocf:heartbeat:VirtualDomain are very fussy.
Sometimes they do not want to start or stop

One of my clusters (fairly old; heartbeat 3.0.0 on openais) runs
VMs on Xen, with storage being directly on the drbd device. I
noticed a similar problem where manual failovers were fine but
cluster-initiated failovers failed. It turned out that setting
a start delay on the xen RA solved the probl

Maybe, but we have no idea if you don't show us your configuration :)

The idea is a setup described as described by Florian Haas in "Virtual
Consolidated High Availability",
(www.netways.de/uploads/media/Florian_Haas_drbd.pdf)
but there are soms details I need to configure better.
I've done the setup before with OpenVZ, but that's different :-)
It's a while since I've done some pacemaker testing, but yesterday
I've done a setup of KVM guests on top off DRBD volumes
This without using shared storage or cluster file systems. (2-node cluster)
I like this setup because it allows applications that can't be
clustered easily to run in an VM.
