[Qemu-devel] [Bug 1655764] Re: qemu-img convert -c compression can't decompress

[Thomas Huth]

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/address@hidden/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."

** Changed in: qemu
       Status: New => Invalid
