A real Linux guest

This terminal is not an animation or a remote shell. The page boots an i686 Linux guest in v86, an x86 emulator compiled to WebAssembly.

Guest
Linux 6.12, i686, 216 MiB
Session
BusyBox PID 1, tmux, zsh and eza
Terminal
xterm 6 with WebGL and a DOM fallback
Network
Disabled in the kernel and emulator
Storage
Immutable initramfs with no persistent disk

Runtime

The page loads SeaBIOS, a Linux bzImage, an initramfs and v86 Wasm. It creates the V86 instance in the page runtime. The CPU loop and Wasm do not run in a dedicated app worker. A small internal v86 Worker schedules emulator ticks.

Terminal I/O

xterm sends UTF-8 input and mouse sequences through UART0. Guest output returns through the same serial port. UART1 carries acknowledged terminal size and browser clock updates.

Build

Nix cross-builds the i686 kernel and userspace. It writes a sorted initramfs with fixed timestamps. Vite bundles the browser code. Nix places all public files under a revisioned release path.

Isolation

The guest has no network device, persistent disk, browser storage or host filesystem adapter. Reset destroys the emulator and starts a clean guest.

Sources and reproduction

The main repository is private. The public source package contains the exact third-party sources and the allowlisted VM build files required for the distributed binaries.

Manifest
Maps public files and guest store paths to sources
Checksums
SHA-256 for each file in the source package
Recipes
Kernel config, initramfs scripts and sanitized shell config
Excluded
CV data, secrets, databases and server topology
