If I try with --force just to see what would end up different in the xml versus after the crm command, I get this error, quite ironically:

Error: unable to create resource/fence device 'vfencing', 'vfencing' already exists on this system

So it complains that it's not on the system when I don't try to force it, and that it is if I try to force it?!
