Are you sure you don't mean to relocate the service to host2 instead
of Migrate? -R will stop/start a service like samba onto another node.
clusvcadm -r <service> -m <host>

I wasn't aware that migration worked for anything other than moving VM's around.

If you look at the resource definition, you'll see that I'm trying to
migrate a VM (the KVM guest is called samba since it hosts a Samba
instance).

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
