Linux Guest

[michealcarac]

Has anyone gotten this working for a Linux guest? The most I get is a screen with red dots on it..

[mrpops2ko]

i'm trying this now and the most i've gotten is seeing a grub screen and then nothing

i also get asome points where i see a while screen upon booting the debian vm too

edit: i also notice on my system that theres another audio device (likely the motherboard back ports for audio) i'm wondering if those are somewhat related

i managed to get this working on ubuntu with a higher kernel but couldn't get it working on debian 12 bookworm because it uses 6.1 - ubuntu 24.04 uses 6.8? so somewhere between that number it starts to work

the problem is that you also face the reset issue and i've not found a solution for that, except but i dont know for sure if that would do it, oh and regarding the audio, on my motherboard at least the passthrough of

What driver did you use for Ubuntu 24.04?

the amd ones, it didn't require any additional setup outside of that for me

but bear in mind that the vendor reset issue exists and would mean restarting the host to reboot the vm - for that reason i went with a windows 11 guest and decided to use VNC to access the other linux guests, then at least i can reboot without having to reboot the host

i make use of vgpu unlock so i can assign multiple different slices of nvidia gpus

Thanks for quick reply.

With Debian 12 Bookworm, the amdgpu driver fails to initialize. With Ubuntu 22.04 Noble, amdgpu doesn't even load. Anything special steps that you did outside of this guide except passing second Audio pci device?

nope, as i said it just worked for me, but i just checked and it was 24.04 (the latest version) not 22.04

I couldn't get it working in Ubuntu 24.04, but I managed to get it working in Debian 12. I have to disabled secure boot at the Debian 12 VM and install firmware-amd-graphics on non-free-firmware repo
