I don't know what "SR" means but yes, you can do live migrations even 
without cLVM.  All cLVM does is ensure consistency in LVM metadata 
changes across the cluster.  Xen itself prevents the source and 
destination dom0's from trashing the disk during live migration.  Other 
multi-node trashings are left to lock managers like OCFS2, GFS, 
not-being-dumb, etc.
