Fully Virtualized Gaming Server?

For years I’ve had a dream of building a rack mounted PC capable of splitting its resources to host multiple GPU intensive VMs:

  • a few gaming VMs
  • a VM for work that can run Davinci Resolve and Blender renders
  • an LLM server
  • a Stable Diffusion server
  • media server

Just to name a few possibilities…

Everytime I’ve looked into it, it seemed like the technology just wasn’t there yet. I remember a few years ago Linus TT took a shot at it, but in the end suggested the technology (for non-commercial entities) just wasn’t in a comfortable spot yet.

So how far off are we? Obviously AI focused companies seem to make it work, but what possibilities exist for us self-hosters who might also want to run multiple displays in addition to the web gui LLM servers? And without forking out crazy money for GPU virtualization software licenses?

You should take a look at https://www.youtube.com/channel/UCp3yVOm6A55nx65STpm3tXQ he does have a serie about doing something like this and go in depth in it

you beat me to it. this is the way.

Unraid does an excellent job at this. I helped a friend setup a rack mounted server, it runs home assistant, some other containers, and a VM for him to work in, or play games. AMD GPU being passed through.

Do you really need multiple VMs, can't you run all at one? The easiest would be to install some windows/Linux on a single machine. Then stream your games with Sunshine/Moonshine and connect over RDP/VPN?

So my desktop is virtio based and uses pcie passthough to passthough the USB controller and GPU. It works fine as long as it has enough cores.

On my laptop I use VMs for a few things and that works well as long as you setup the proper guest addons. I use KVM with gnome boxes and virtual manager.

Xen has support for AMD cards intended for this that are fairly inexpensive on eBay. The S7150x2 should be what you're looking for.
