Virtio-nvgpu: Near-native Nvidia GPU access inside a KVM guest
Developers have introduced virtio-nvgpu, a virtual device that enables Nvidia GPUs to be accessed from KVM virtual machines with performance close to bare metal. The driver leverages the virtio framework to pass through GPU resources, supporting CUDA and graphics workloads while reducing overhead compared to traditional PCI passthrough. Early benchmarks show significant speed improvements for GPU‑intensive tasks.
