Linux FAQs with Answers--How to fix “hda-duplex not supported in this QEMU binary”
|
|
================================================================================
|
|
> **Question**: When I try to install Linux on a new VM in virt-manager, the VM fails to boot with the following error: "unsupported configuration: hda-duplex not supported in this QEMU binary." How can I fix this error?
|
|
|
|
The cause for this VM error may originate from a qemu bug where a configured default sound card model is not recognized.
|
|
|
|
|
|
|
|
Unable to complete install: 'unsupported configuration: hda-duplex not supported in this QEMU library'
|
|
|
|
To solve this problem, do the following.
|
|
|
|
### Solution One: Virt-Manager ###
|
|
|
|
On **virt-manager**, open the VM's virtual hardware details menu, go to sound device section, and change the device model from default to ac97.
|
|
|
|
|
|
|
|
Click on "Apply" button to save the change. See if you can start the VM now.
|
|
|
|
### Solution Two: Virsh ###
|
|
|
|
If you are using **virsh**, not **virt-manager**, you can edit the VM's XML file accordingly. Look for **sound** section inside <device> section, and change the sound model to **ac97** as follows.
|
|
|
|
<devices>
|
|
. . .
|
|
<sound model='ac97'>
|
|
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
|
|
</sound>
|
|
. . .
|
|
</device>
|
