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.
Not sure about your issues but I was able to do single gpu pass through in Nvidia with this guide which seems to show amd as well https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home
