I use set of: * qpid server * libvirt-qpid on each host which runs VMs * fence-virtd with multicast listener * fence-virtd-libvirt-qpid (patched, patches were posted to pacemaker list 03.10.2011 for those who need it) * fence_xvm as a fencing agent Major problem I recently discovered is that you can have only one instance of fence_xvm process running (executing) on a node simultaneously, because it binds to predefined port.
