Huh?! If you ever tried changing the order of PCI devices such as
virtio-blk-pci on the command line (or changing between if=virtio and
-device virtio-blk-pci) then surely it does change the order of the
/dev/vdX the guest sees and will be migration-incompatible. The order of
-drive and -device however, for instance, does not seem to matter. But
in this generality, your statement does not seem to reflect current reality.
