Description of problem:


Version-Release number of selected component (if applicable):
# uname -r

# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.148.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1./usr/libexec/qemu-kvm -soundhw ?

  
Actual results:
# /usr/libexec/qemu-kvm -soundhw ?
Valid sound card names (comma separated):
pcspk       PC speaker
ac97        Intel 82801AA AC97 Audio

The patch doing the windup for '-soundhw hda' was not backported to RHEL, so the output is actually correct.  Using the -device switch is the recommended way to create the device (libvirt does it this way).

I don't see a strong reason why -soundhw should be supported in RHEL.
If there is one please reopen and explain.

Hi, Gerd 

# /usr/libexec/qemu-kvm --help|grep sound
-soundhw c1,... enable audio support
                and only specified sound cards (comma separated list)
                use -soundhw ? to get the list of supported cards
                use -soundhw all to enable all of them

if the command is not supported , should it remove from help doc ?

I don't think this is worth the trouble.

Invoking qemu-kvm directly isn't supported, only via management (i.e. libvirt).
You are not supposed to see the help output in the first place ;)
