pacemaker query

Is anyone here using pacemaker clustering? I have a question about monitoring... if I create my resource (a xen vm) in an unmanaged state initially, the monitor is never called. This is contrary to what I thought should happen, and from what I've read. If I do 'crm status ops' there is no entry for it, presumably because it has never run on a node (even though the VM is actually running). Am I doing something wrong, or is this the expected behaviour? Thanks James
