Huh?! If you ever tried changing the order of PCI devices such as virtio-blk-pci on the command line (or changing between if=3Dvirtio 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 reali= ty.
