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.
