Thanks for sharing! I'm not sure your table under Why Clone is quite correct.

10x 512MB idle VMs should not take 5GB on Firecracker if they are started from snapshots since the 512MB memory file is mmap'ed with MAP_PRIVATE so is copy on write.

Firecracker has diff snapshots: https://github.com/firecracker-microvm/firecracker/blob/main...
