Show HN: CUDA/graphics in QEMU-KVM VMs without passing the Nvidia card to them

https://github.com/reindertpelsma/nvkvm-pv
3•reindertpelsma•43m ago
Hi HN. I built this because I wanted a VM with a real GeForce GPU without losing the card on my desktop.

It allows you to run CUDA and graphics in VMs without VFIO/vGPU by forwarding the NVIDIA driver's own ioctl surface from the guest to the host.

That means stock libcuda and real Vulkan ICD run in the guest - no CUDA/Vulkan API remoting or translation. Display, LLM, CUDA, headless supported. Your desktop keeps using the same card, multiple VMs supported.

Happy to go into the details of the architecture.

This is super interesting and potentially extremely useful as well. What is the performance improvements against doing it via API remoting or translating?
