Single GPU passthrough on Qemu not working

Post by TTVARTISM0 »

So im trying to do a single GPU passthrough with my Nvidia 3090 ti via following a tutorial on YouTube but when I click run it crashes qemu and when I boot back into it it says it's stuck on connecting I think it may be due with me messing up the directory structure of the hooks file but I don't know for sure so does anyone know how to fix this issue?

Start by posting a link to the tutorial. I also strongly suggest to choose a printed tutorial that shows you each step in written form.

There are many possible reasons for the failure. For example, have you created a suitable VBIOS file for the Nvidia graphics card?

You can also use journalctl or dmesg to get the errors that led to the qemu crash. Or better, go through the following to get the errors:

Code: Select all

sudo cat /var/log/libvirt/qemu/your_vm.log
Post the relevant part here and perhaps I or someone else will be able to help.
