Which version of QEMU (or rather qemu-img) are you using?

When reporting bugs, please always use the latest version of QEMU, old
versions like 2.1 are not supported anymore. I just also noticed that
Stefan Hajnoczi replied to the bug mail on the qemu-devel mailing list
(see https://www.mail-archive.com/qemu-devel@nongnu.org/msg422186.html)
- seems like the bridge did not mirror this to the bug tracker:
"QEMU image compression uses the compression feature available in some
disk image formats (like qcow2). This is not the same as compressing a
file with gzip, bzip2, or similar tools.
Therefore this error is expected and not a bug."

Yes used qcow2 format only when compressing, I don't think due to older
version problem
