Description of problem:
Since the '-writeconfig/-readconfig' option has been support in rhel6.3 and will easy to debug, but there is no '-writeconfig/-readconfig' option help doc in qemu-kvm manpage, while exiting in the whitepaper. so we should update it.
Version-Release number of selected component (if applicable):
# uname -r && rpm -q qemu-kvm*
Steps to Reproduce:
1.# man qemu-kvm | grep writeconfig
# man qemu-kvm | grep readconfig

Proposed patch to add -readconfig/-writeconfig command line options
This is the patch to include -readconfig and -writeconfig command line
options to the QEMU man page. Those commands are useful when using
many devices and/or command line arguments in general to save space
in the QEMU command line.
Reproduce on qemu-kvm-0.12.1.2-2.295.el6.x86_64&kernel2.6.32-279.el6.x86_64, and verified on qemu-kvm-0.12.1.2-2.331.el6.x86_64&kernel2.6.32-335.el6.x86_64.
So this bug was fixed.
Verified this issue on:
The man page output is in follow:
#man qemu-kvm | grep -A4 writeconfig
Write device configuration to file. The file can be either filename
to save command line and device configuration into file or dash
"-") character to print the output to stdout. This can be later
used as input file for "-readconfig" option.
# man qemu-kvm | grep -A4 readconfig
Read device configuration from file. This approach is useful when
you want to spawn QEMU process with many command line options but
you don’t want to exceed the command line character limit.
