I am curious if the following is possible. Currently, I have my Nvidia GPU setup for pass-through to my windows KVM. I'm using an AMD GPU within my main Linux system. I want to know if I can use my isolated Nvidia GPU for tasks such as Stable Diffusion on the main machine when it is isolated or if I will need to have both GPU's setup for the main system ~ and if I did have a dual GPU setup, would this then prevent pass-through to the KVM?
If needed, here are the exact gpus on my system:
$ lshw -c display

Overall I want to know if I can use my Nvidia GPU for tasks when my kvm is not running.

well - as long as the vfio driver is used for the gpu it will only provide pass-thru capabilities - as you need any gpu driver loaded for it to be recognized as gpu - otherwise it's just any non-gpu-device
I'm not sure about hot-swapping used driver - but I've seen scripts so it seems possible

Got it, I seemed to have gotten my desired functionality by following the hybrid graphics walkthrough. I can still pass-through to the KVM, but can prime-run when the KVM isn't running.

Hey @nv3r, can you speak more to how you got this to work using prime-run with vfio?
As far as I can gather with my hybrid intel/nvidia setup, using the vfio driver for my nvidia card means that it can only pass through to the kvm and otherwise I'm unable to use it (i.e., with prime-run). Can you share your kernel command line and any other configuration steps that you did?
Thanks!
