Saving of the execution state of a VM is basically identical to
migration. In case of qemu it is actually implemented using a migration
into the save file.

Certain configurations simply don't work with it either due to technical
reasons (e.g. restoring state of a hardware device might not be possible
to the extent that it's transparent to the guest OS) or not implemented.
