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. More info: https://lists.fedoraproject.org/pipermail/virt/2012-December/003503.html
That command should be: yum downgrade qemu\*
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.
