Description Kevin Wolf 2013-10-29 12:30:07 UTC 
The qemu manpage in RHEL 6 doesn't document the rerror/werror/readonly options
for -drive, even though these options are implemented. They should be added to
the manpage.
Comment 1 Miroslav Rezanina 2014-01-27 07:51:03 UTC 
Fix included in qemu-kvm-0.12.1.2-2.420.el6
Comment 3 Chao Yang 2014-07-01 05:54:21 UTC 
Steps to reproduce and verify this issue:
1. dump output of man qemu-kvm for fixed qemu-kvm and unfixed qemu-kvm
2. run diff on them

Tested with qemu-kvm-0.12.1.2-2.428.el6.x86_64 and qemu-kvm-0.12.1.2-2.415.el6.x86_64. Actual result is as below:

# diff -up qemu-kvm-man-old qemu-kvm-man

As per above, this issue has been fixed.
