Is there any other proposals to implement vm-snapshot?See the discussion by Paolo and Andrea about post-copy migration, which adds kernel memory management features for tracking userspace page faults. Perhaps you can use that infrastructure to trap guest writes.
That infrastructure actually traps guest reads too. But it's fine, as they are a superset of guest writes and the image will still be consistent.
