Yes, you need to tune xen.
But for production use, running heartbeat inside a virtual environment
isn't really supported; how do you handle fencing?
And Xen interferes with heartbeat's needs to run at realtime priority;
you'd at least be better off increasing the deadtime values and the
default-action-timeout variable.

For that, it needs to miss the deadlines by so much that it actually
times out a monitor operation! (I take it you have configured one.)
That's quite, uhm, unlikely, but of course possible.
