Now I use qemu-img to convert "delta.qcow2" and will get a new image file "new.qcow2" which is entire and equivalent to combination of "base.qcow2" and "delta.qcow2". In fact,I don't want to get a complete image.I just want to convert delta qcow2 image file "A" to a New delta overlay qcow2 image "B" which is equivalent to "A". So the "new.qcow2" is not what i want. I have to admit that this is not bug. Could you please take this as a new feature and enable qemu-img to convert qcow2 overlay itself?
