Hello,
I have a problem with my GPU passthrough with Qemu 2.1.2 on Ubuntu 14.04. I have a Windows 10 VM up and running, all is working well, the graphic card is available (NVIDIA Geforce 960) and the drivers are installed. I can play over Steam on a thin client. Only the audio makes problems. Windows says the audio device is not responding.
I used this guide: http://vfio.blogspot.co.at/2015/05/v...our-first.html
lspci -nnk:
Both of them are passthroughed to the machine.
VM XML:
First I thought the audio device is not correctly passthrough, but it uses the correct driver I think.
Maybe anyone has an idea, why this is not gonna work, do I need a dummy audio adapter maybe?
Best regards
Dominik
