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:

Resource file (ocf::VirtualDomain) is active on 2 nodes attempting recovery
Sep  2 18:14:05 host2 pengine: [1735]: WARN: See
