Ah. Does manual migration through virsh work rather than clusvcadm?
If it does -- I'd put rgmanager into some extra logging by editing
/etc/init.d/rgmanager with RGMGR_OPTS="-dddd" under the RGMGRD part.
Then restart rgmanager and check logs for more info after trying clusvcadm
-M again. (add debug to host / target servers and see if you catch anything
new)

Good luck
Henry
