this is a chicken-and-egg problem. libvirtd has to be started for VirtualDomain RA probing to work. If you start libvirtd as a cluster resource this is too late, start it via init. On probing errors Pacemaker can't reliable tell if a resource is started outside cluster control, so for safety reasons a restart is triggerd -- stop on all nodes, rstart it on only one node: Sep 2 18:14:05 host2 pengine: [1735]: ERROR: native_create_actions: Resource file (ocf::VirtualDomain) is active on 2 nodes attempting recovery Sep 2 18:14:05 host2 pengine: [1735]: WARN: See http://clusterlabs.org/wiki/FAQ#Resource_is_Too_Active for more information.
