Virtio-nvgpu gives near-native Nvidia GPU access in KVM guests
virtio-nvgpu forwards NVIDIA kernel driver ioctls at the driver ABI level, letting a Linux guest run the vendor's own unmodified user-mode drivers. On an RTX 3060, guest performance is within 2% of bare metal above about 2 ms per frame and costs the same CPU; four guests together hit about 103.7 fps, targeting headless streaming.
