Hi,

 

I am very new to passing trough GPU'S but I have encountered the error 43 with no solution so far.

I am running a gtx 1060 in a isolated IOMMU group an I am passing trough the card and audio

I have tried the following:

- With and without graphics rom

- various xml edits like hiddenstate and so on

- SeaBios and OVMF

 

I am running a Ryzen with the nvidia as primary gpu and the screen goes blank once I start the vm

I have installed all virtio drivers

 

And in addition my XML:

Are you running a headless system?

If so are, running in UEFI or Legacy mode? (Found in Shares > Flash > Legacy Mode)

If in UEFI mode try running in legacy mode and with a graphics rom, this fixed my problem with my 1050-Ti when I was getting Code 43s
