[Pacemaker] Xen, Pacemaker and live migration

[emmanuel segura]

Hello Frank

The first thing I found wrong in your config is

=====================================================
colocation CLVMCloneWithLVMforVM1 inf: LVMforVM1 clvm-clone
=====================================================

clvm-clone must be a resource running on every cluster node, not just where
lvm for the vm1 it's running
