> A Rust microVM with GPU sharing for cloud gaming: guests render near bare-metal speed and boot in about a second. Requires KVM, a GPU with a DRM render node, and a custom kernel with Mesa.

## Useful for

- Run several short-lived Linux microVMs sharing one GPU for game streaming
- Build a custom guest kernel with VIRTIO_PCI, DRM_VIRTIO_GPU and VSOCKETS
- Benchmark guest rendering against bare metal using docs/BENCHMARKS.md

## Why it’s here

- 24 stars so far today, about 31 expected by the end of the day. The usual pace is 0 per day, so that's 31× as much.
- Before this, the repository barely got any stars — about 0 per day.
- The spike has held for 2 days in a row — not a one-off blip.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1
- Issues and pull requests: 9

1. **nestrilabs/virtio-nvgpu** — 6.2 · Early signal · DevOps & infrastructure · Rust · +124 stars today, ≈ 164 by evening
   An experimental virtio device giving KVM guests near-native NVIDIA GPU access by forwarding driver ioctls, bypassing API-level translation. Aimed at headless streaming: a compositor in the VM renders and encodes frames on the GPU.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
