qemu 1.3.0 error: unsupported configuration: hda-duplex not supported in this QEMU binary
Last modified: 2013-01-09 07:12:19 EST
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"
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.
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.
