This is a port of QEMU machine emulator to JavaScript using Emscripten.
The port targets single-threaded WebAssembly and contains a proof-of-concept WebAssembly JIT. For now, only 32-bit guest are supported.
This time, it is branched from the upstream master branch and now this repo does not require separate qemujs-build. This rewrite is still even more work-in-progress than the original one and still does not support block devices.
Here is my article (in Russian) about Qemu.js.
Some similar pre-existing projects:
- JSLinux -- machine emulator written by Fabrice Bellard, the original author of QEMU
- Virtual x86 -- another JavaScript machine emulator
- another attempt (now frozen?) to port QEMU to JavaScript
