Description John L Magee 2012-12-09 16:08:41 UTC 
Description of problem: VM fails to start

Version-Release number of selected component (if applicable):  virsh version
Compiled against library: libvirt 1.0.0
Using library: libvirt 1.0.0
Using API: QEMU 1.0.0
Running hypervisor: QEMU 1.3.0

How reproducible: always

Steps to Reproduce:
1. attempt to start VM with sound model ICH6
2. observe error "error: unsupported configuration: hda-duplex not supported in this QEMU binary"
3.
  
Actual results: VM fails to start

Expected results: VM starts

Additional info: also fails with codec 'micro'

Note that Windows 7 does not support any of the other sound devices natively, if at all. So this will prevent the use of sound on Windows 7 guests until it is resolved

I assume you are using the virt-preview repo?

I accidentally pushed qemu 1.3 to virt-preview even though it is known not to work with libvirt 1.0.0. I'm fixing that now, please do a 'yum downgrade qemu' and restart libvirt.

Comment 2 Cole Robinson 2012-12-09 16:52:05 UTC 
That command should be:

yum downgrade qemu\*
Comment 3 John L Magee 2012-12-09 17:24:16 UTC 
downgrade worked fine and, of course, resolved the issue.

FWIW, my XP VM worked fine and so did the WIN7 VM when I changed the sound device. And, the issue with qemu crashing after spice disconnect when using es1370 sound device appeared to be resolved when I did a quick test.

Thanks much for the quick response.
