This is just straight save+restore, akin to hibernate-to-disk for a
physical machine.
This is a fundamentally broken concept. You cannot just save the
guest's memory state without saving the current state of the storage.
Oh -- let me follow up on how this works in libvirt:
The "save" and "restore" commands shut down and start the VM when
invoked; consequently, no storage changes are made while the VM is
down. Restoring more than once off the same "save" is not an intended
use case.
