Show HN: vGPU and SR-IOV on consumer GPUs

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.

Note Intel GVT-g is only available on <=Gen9 GPU's. Gen11 and 12 are not supported.

GVT-G has hard resolution limitations and was never stable with QEMU on Linux

GVT-g uses KVMgt. Intel has not yet upstreamed their patches.

Great! Still requires vGPU support and the merged driver approach last time I tried won't support CUDA on host (I was probably the first one tried the merged driver thing with vgpu_unlocked?).

Looking forward someone write a Vulkan driver on Windows that just shuttles down to the Linux host. virgl used to be a promising project ...

It also works on Intel's ARC and DG1/DG2 discrete GPUs.

Our software also works on most consumer Nvidia cards and also some consumer AMD cards.
