I'd suggest to use something like SBD or fence_sanlock (depending on
which distribution you run, we have multiple implementations of the
wheel).

If you're running HA *within* the VMs, just treat them like you'd treat
physical nodes. Except for choosing an appropriate fencing mechanism,
nothing special.
Oh - if your hypervisor does something like live migrations, make sure
the timeouts of the cluster don't trigger during one. But normally
that's not a problem.
