So if your code doesn't work correctly if the block numbers are monotonically increasing in the qcow2 image, I would *have* to assume there would be plenty of qemu-generated images files that don't have this constraint (i.e., suppose you write blocks 10000, 42, 16, and 24 while running under qemu, presumably that is the order the blocks would be written and would show up in the qcow2 file). Or am I misunderstanding what you are saying here; is it that you are fairly sure the code will break if the data is not laid out sequentially, or that you've never tested this case?
