Speaking of that, if the guest RAM were a memory-mapped file, couldn't
that use shared storage too?
You'd have to be careful: it would need a distributed filesystem with
coherent mappings (i.e. not NFS), but they do exist.
I'm guessing that the bulk of time spent in migration/checkpointing is
saving the RAM image. Using a memory-mapped file on shared storage
for RAM might make that faster. (Or slower!).
