[solved-ish] Virtual machine gaming

Hey there,

I occasionally play windows-only games (not compatible with Wine etc.), however I loath the idea of dual booting just because it can be better.

So I've done some research(DDG searches) and it could be possible giving the right hardware and 2 GPU's, meaning 1 dedicated for the VM. However the topic's I read where quite out of date, so I figured I'd ask here.

is it possible having 1 GPU and still use that GPU for the virtual machine as well as for the host?

Nope. Afraid not.

People usually use their integrated GPU for the host OS.

This thread can give you some ideas.

Re: [solved-ish] Virtual machine gaming

You can run the VM on a different GPU using GPU passthrough:

The second one is based on tmp-meteque's link, so you're probably better off there

Yeah, but I have some games running on Linux as well :s. So that would require me to reboot everything I want to run a game on either linux / windows in order to switch the GPU.
This does seem like the optimal solution at the moment though.

My question was if I could run it with 1 though ;p

You want to run 2 systems on 1 GPU? Don't think that's possible.

Re: [solved-ish] Virtual machine gaming

I may have read on the vfio-users ml where some people were able to switch the discrete GPU between host and VM usage without rebooting. OTOH it may have just been a "hopes for the future" thing.

Regardless, the ml is a better resource about VGA passthrough than these forums IMO. You should also checkout Alex William's vfio blog.

Great! Thanks, I'll look through it .

Sure that makes sense, this is just the only Linux forum I'm on and I just wanted to know if it was possible since my searches didn't really answered my question. I'll mark this as solved.
