What I said especially applies for single GPU passthrough, minus the two GPU part, I say that because I’ve done that on Desktop.

Single GPU passthrough (for me) was a journey of misery where a series of bash scripts with crude busyloop synchronization kept me from having no display output and needing to restart my system to test my changes again.

It’s probably the last thing I’d recommend for someone who wants something that works, unless you know something I don’t.

GPU passthrough requires two GPUs, a system with compatible components, a lot of caffeine and a lot of patience. Not something for someone who wants something that just works.
