Scratch a Rust Hypervisor

Building a bare-metal ARM64 Type-1 hypervisor from scratch in Rust, using AI pair programming.

This is the story of rebuilding a production-grade hypervisor — a journey that previously took 10 months — in about 1 month, using Claude Code and vibe coding.

From the first boot.S to pKVM integration with FF-A v1.1, every commit is documented. Each chapter covers the technical implementation alongside the AI collaboration process.

What You'll Learn

• ARM64 virtualization (EL2, Stage-2, GICv3, PSCI)
• Rust no_std bare-metal programming
• Linux kernel boot process under a hypervisor
• ARM FF-A firmware framework and Secure World
• AI-assisted systems programming workflow

The Repository

All code is at github.com/willamhou/hypervisor — 191 commits, 33 test suites, ~282 assertions.
