I've had this issue too.  It isn't a Xen issue, it's a cluster problem. 
 I've found that clvmd sits there waiting on a lock one of the other 
nodes holds open.  I haven't yet found how to determine which node it is 
that's doing it, so maybe there's some magic out there to accomplish that.
Make sure you shut down the node by turning off all of your domU's, 
`lvchange -an,` then shutdown clvmd and cman before rebooting.
