In this case this command is not working at all, because I tried in
the past for many resources and it never worked, so I just assumed it
has to be implemented by RA.

To test it right now I issued a command
# crm resource restart xen_vbuild

where xen_vbuild is a Xen VM and no results whatsoever.

Here is output of the log

still ID 3 as it was before
