- Tutorial on building a hypervisor from scratch in 1,000 lines of code.
- Focuses on a type-1 hypervisor for 64-bit RISC-V with hypervisor extension (on QEMU).
- Target audience: developers who completed 'Operating System in 1,000 Lines'.
- Written in stable Rust, not requiring nightly builds.
- Hypervisors described as hardware-assisted event handlers, akin to a 'catch' block in JavaScript.
- Potential applications include emulating hardware, security boundaries like gVisor, and application-specific environments like Hyperlight.
