Nope, there's stuff that's on the filesystem that is tied to the QEMU

Ok, there is no guarantee that the VMs won't write concurrently to the disk during migration?
Also, there are cases where VM disks/images are readonly, or image-less VMs.
Except the obvious testing case, there are other use cases that could be interesting: moving a running VM from system to session libvirt, or the other way around, or to a different user.
