You're supposed to have /var/lib/libvirt/images mounted via shared storage (nfs/cifs/etc) on both machines.
I've heard of folks having trouble doing live migration over NFS -- something with stronger concurrency guarantees (GFS, a shared iSCSI or FC mount [possibly with cLVM to partition it up], etc) is likely to be a safer bet. (Indeed, looking at the documented preferred environment for VMware's VMotion is probably a good guideline for anything that's going to be trusted with real production usage -- a separate bonded pair of NICs on each host, connected to a dedicated network for communication with the SAN hosting the backing store).
