virtio-nvgpu
Near-native NVIDIA GPU access inside a KVM guest. A guest renders within 2% of
the machine it is running on, and costs the same CPU.
virtio-nvgpu
forwards NVIDIA kernel driver ioctls between a Linux guest and
the host at the
driver ABI level
, bypassing API-level translation entirely.
The guest runs NVIDIA's own user-mode drivers, unmodified — the same libraries,
the same Vulkan and NVENC, talking to the same card.
The target is
headless streaming
: a compositor inside the VM renders,
composites and encodes frames on the GPU, then sends compressed video out. The
VM has no monitor, and the host keeps the card.
Where it stands
It works, and it has been measured.
A Wayland client presents inside a
guest, the capture layer encodes on the game's own device, and the H.264 comes
out (EN)
