Hi Lidong Chen:
I used QEMU 2.0.0 on Ubuntu 14.04.

qemu-img convert a overlay qcow2 image into a entire image
Status in QEMU:
I have a base image file "base.qcow2" and a delta qcow2 image file
"delta.qcow2" whose backing file is "base.qcow2".
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?
