Description Kevin Wolf 2013-03-21 10:22:02 UTC

qemu-img convert accepts the -s parameter, but silently ignores it. This is
caused by a bad backport in commit 38d60cb2.

As the functionality isn't present in RHEL 6, it should instead error out and
show the help text as with any unknown option.

# qemu-img convert -f qcow2 win8-64-virtio.qcow2 -O raw sluo.raw
            <-----it can complete successfully.
# qemu-img convert -s -f qcow2 win8-64-virtio.qcow2 -O raw sluo.raw
qemu-img: Could not open 'qcow2'
qemu-img: Could not open 'qcow2'

-Verify this issue:
host info:
kernel-2.6.32-382.el6.x86_64
qemu-kvm-0.12.1.2-2.375.el6.x86_64

# qemu-img convert -f qcow2 win8-64-virtio.qcow2 -O raw sluo.raw
            <-----it can complete successfully.
# qemu-img convert -s -f qcow2 win8-64-virtio.qcow2 -O raw sluo.raw

usage: qemu-img command [command options]
QEMU disk image utility
...

'-s' doesn't exist on RHEL6 for for the qemu-img convert, so trying to use it should result in an prompt message. 

Base on above, this issue has been fixed correctly. Set this bug to VERIDIED status, please correct me if any mistake.
