Xen Hypervisor to be Rewritten

The hypervisor team has come to the conclusion that using the C programming language, which is 45 years old as of writing, is not a good idea for the long term success of the project.

C, without doubt, is ridden with quirks and undefined behaviours. Even the most experienced developers find this collection of powerful footguns difficult to use. We’re glad that the development of programming languages in the last decade has given us an abundance of better choices.

After a heated debate among committers, we’ve settled on picking two of the most popular languages on HackerNews to rewrite the Xen hypervisor project. Our winners are Rust and JavaScript.

Rust, although not old enough to drink, has attracted significant attention in recent years. The hypervisor maintainers have acquainted themselves with the ownership system, borrow checker, lifetimes and cargo build system. We will soon start rewriting the X86 exception handler entry point, which has been a major source of security bugs in the past, and looks like an easy starting point for the conversion to Rust.
