This is insanely impressive. Having tried set up GPU passthrough in proxmox a few years ago, it was an absolute disaster. I would love to see this kind of approach more widely supported by other hypervisors! It's a real shame consumer GPUs are arbitrary locked down when the enterprise counterparts (often with the exact same chip) have much better support for virtualization.

The enterprise versions of these products have a lot of bugs and gotchas because so few use the feature.

  I'm making this because I had the same problem. My hope is that we can move the needle a little bit.

    As far as I'm concerned anyone that's working of virtualized GPU is doing the Lord's work.

Ya the lock out is absolutely arbitrary. There is zero physical difference between the consumer and server chips for these features. I think actually there's a lot of benefit to consumers by having these features enabled! I talk about that a bit here in our Xorg Developer Conference 2021 talk: https://www.youtube.com/watch?v=8pVrTyLqV_I https://www.youtube.com/watch?v=8pVrTyLqV_I We're going to try to add support for more distributions in the coming days. Right now we've got support in our install script for Ubuntu 20.04 hosts and arbitrary guest operating systems (Windows guests work best so far) but if people on GitHub are posting issues asking for support for other systems I'll try my best to get to those. I'm going to try to add official support for Arch, PopOS, and Fedora as I know some people who I think would use it on those systems and a few others.

  Is the process of unlocking these features on Nvidia GPUs similar to something like the vgpu_unlock tool is doing?[1] No affiliation, just came across it trying to find a replacement to the deprecated RemoteFX vGPU and am out of my depth.

    For replacing RemoteFX vGPU, what you might want is https://forum.level1techs.com/t/2-gamers-1-gpu-with-hyper-v-gpu-p-gpu-partitioning-finally-made-possible-with-hyperv/172234 https://forum.level1techs.com/t/2-gamers-1-gpu-with-hyper-v-... (which is the direct successor) The advantage is that it ships inbox in Windows and doesn't need license hacks or anything. It works cross-vendor too. However, it needs the host OS to be Windows (with Hyper-V being used).

      Interesting! News to me, the Microsoft documentation I was looking at didn't make any mention of GPU-P but that seems like a perfect fit. Was looking at a old Grid K2 to avoid Nvidia licensing and direct pass through for high use VMs but as we're full Microsoft (for better or worse) their solution probably makes more sense. edit - apparently while this works on Server 2019 direct pass through is the only officially "supported" option. I wonder if this is a stepping on partners' toes sort of situation?

        GPU-P is also the GPU acceleration infrastructure used for GPU acceleration in WSL2 and for Windows Sandbox too.

        I'm not entirely sure on how wide the vendor support is but I wouldn't be entirely surprised if they were upsetting some folks with it. Happily we're just a little team right now making stuff that's useful for ourselves so we don't have all the same pressures big companies have. I hope if we ever grow we'll act in the same spirit (I'll try my best to see that we do anyway).
