Summary: qemu-img -c not working

Initial Comment:
With kvm-56, running:

qemu-img convert -c winxp64.img -O qcow2 test.img

qemu-img: Alternative compatibility level not supported for this file format

-c is for compressed target source image. Naturally, .img file is not compressed.
Did you wanted to compress the destination?

Anyway qemu is the right place for these type of bugs.
Thanks,
Dor.

Looking at the source of qemu-img.c, there is an obvious bug at line 474 (if the usage text is to be trusted):

if (flags & BLOCK_FLAG_COMPRESS && drv != &bdrv_vmdk)
    error("Alternative compatibility level not supported for this file format");

This should probably be BLOCK_FLAG_COMPAT6.
