Even if this patch gets NACKed, this part should be pushed as a separate 
patch (maybe with some tuning), as it breaks the backward compatibility 
with daeamons compiled against older versions of libvirt.

After calling this command against an older libvirt "error: unknown 
procedure: 243" appears and the command fails. This is because the 
remote driver supports the procedure but the RPC server doesn't. The 
error to be checked for should also contain VIR_ERR_RPC, which is 
reported on missing procedure on remote end.
