Good day, I have some really hard time getting my GPU passed through to a VM, my current host is Linux Mint 21.1. The bios setting is fine, but for some reason I get a black screen every time the VM starts. I have narrowed it down to the startup hook script, where it is stuck (meaning it wont do the following) when it is doing the ‘virsh nodedev-detach’ instruction.
virsh nodedev-detach pci_0000_09_00_0 virsh nodedev-detach pci_0000_09_00_1
Following the instructions of the following link: https://www.reddit.com/r/VFIO/comments/n35k69/successful_6800_xt_passthrough_are_such_posts/
I’m not sure if the card itself have limitations, or is it LM. Just want to confirm whether I am wasting my time on this card? Or if it is the combination of both Linux and my GPU I’m basically try to do a single GPU pass-through with scripts that will release GPU from host and pass through to VM, till the VM is shut down, then the host have control over the GPU again.
You have one GPU card? If yes you need some additional hooks (kill DE sessions, stop X, etc). Look here: https://github.com/joeknock90/Single-GPU-Passthrough .
UPD: Sorry. I read the reddit post. So you pass through single GPU. You load GPU bios when Windows load?
In general, such a configuration will be quite complicated, but if you want to try, show the VM configuration and the start hook. Without this not easy to say.
