Multiple nvidia GPU's with different drivers for qemu virtual machine
Hello fellow people of the arch wiki, I have a bit of a problem I am trying to solve. I have 2 Nvidia cards that require different drivers, an RTX 3080 and a GT 710. My end goal is to boot to terminal, with the choice of either launching a virtual machine where I can run windows for VR gaming, or launch my standard plasma wayland desktop using SDDM. I have a dual monitor setup, where both monitors are attached to my 3080 via DisplayPort, and my GT 710 is attached to one monitor via HDMI. I can't seem to find anything on how I can accomplish having 2 different drivers installed for 2 different gpus when they are both Nvidia. Currently I am using nvidia-open drivers for my 3080, and my GT 710 is in the machine.
Beginning to wish I never bought an Nvidia GPU.

Re: Multiple nvidia GPU's with different drivers for qemu virtual machine
Do I even need a driver for the GT 710 or should it just work since all I am doing is using the terminal?

Unless you intend to exclusively pass one of the GPUs through to the VM (in which case you don't need any linux drivers for that GPU) this will require you to jump through some hoops and the short version is that you cannot load the 390xx and 5yyxx drivers at the same time (so you'll have to juggle things around at boot or runtime)
https://wiki.archlinux.org/title/Vfio
If you're not trying to pass one of the GPUs to the VM, what's the point of having both anyway?
And if you want to reboot to switch between the windows VM and linux, why do you run windows in a VM tbw?
