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).
