nestrilabs/virtio-nvgpu
[Experimental] A virtio device for near-native NVIDIA GPU access in KVM virtual machines.
virtio-nvgpu is an experimental Rust-based virtio device that forwards NVIDIA kernel driver ioctls between a KVM guest and the host at the driver ABI level. The guest runs unmodified NVIDIA user-mode drivers, targeting headless GPU streaming where a compositor in the VM renders and encodes H.264 on the host's GPU. Benchmarks show guest performance within ~2% of bare metal for game-sized frames, with several guests sharing one card.
Why now: It was featured on Hacker News, and it's remarkable because it claims near-native (within 2%) NVIDIA GPU performance in VMs without GPU passthrough — long a pain point for cloud gaming and virtualization.
Who it is for: Developers and operators building cloud gaming, GPU streaming, or virtualized GPU workloads on Linux/KVM with NVIDIA cards.
