This is interesting. Is it hypervisor-agnostic? Ideally, I would like to use something like this without being forced to use a specific file system. This is essentially what qcow2 does, and it's a shame that it's not supported by all hypervisors. But then your implementation would need to be much more complex, and implement what CoW filesystems give you for free, so I appreciate that this is possible in 600 LOCs. Also, your repo doesn't have a license, which technically makes it unusable.
