Both the qemu-kvm-rhev-2.1.0-3.el7ev.preview.x86_64 and qemu-kvm-rhev-1.5.3-60.el7ev.x86_64 can hit this issue too.

# qemu-img convert -c -f qcow2 -O qcow2 sourcecompress.qcow2 blkdebug:blkdebug.cfg:compressed.qcow2
qemu-img: blkdebug:blkdebug.cfg:compressed.qcow2: error while converting qcow2: Driver 'blkdebug' does not support image creation

Best Regards,
sluo

Closing because (as discussed for BZ 1122788) we don't need to be able to create files over blkdebug.

Also, in contrast to RHEL 6 (BZ 1122788), the error message is very clear in RHEL 7.
