Dear all,
I am passing my GPUs to an Ubuntu 24.04 virtual machine. Everything works so far, with two RTX 2080Ti or RTX 2080Ti + Rx9700. However, when adding an RTX 5090 alongside an RTX 2080Ti, the RTX 2080Ti no longer works. with this error:
In the last two days, I've already tried different options and suggestions, e.g. changing the BIOS type or adding an argument. I also reinstalled Ubuntu and tried different drivers, but nothing has worked so far. Your help is appreciated!
Here are some terminal outputs:
and here is my VM config:
