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

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.
