qemu-img convert -s is silently ignored
Last modified: 2014-03-28 09:17:06 EDT
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.

'-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.
