Hypervisor 101 in Rust

I believe this was written by the same person who wrote Operating System in 1000 Lines[1] which was high quality and super fun to work through. So this is definitely going on the rainy day list.

A book from this person would be amazing!

The guide itself is great.

But I really dislike these markdown books used by many rust projects. I wish they just had an option to download it as a PDF, so that I could archive them. The printing button really isn't good enough for that. I mean if everything is already neatly renderd to HTML like that, how hard could it realistically be to also create a good looking PDF version...

Would have been better to link to the repo [1] directly.

The repository contains the materials of a class, so without attending the class or having a rather strong pre-existing knowledge about hypervisors on x86-x64, the material is going to be very hard to follow.

From my PoV, there are definitely better (as in, explained with a lot more details) tutorials online on how to start your hypervisor from scratch which I'd recommend before trying to understand this one (which has some really nice peculiarities such as Fuzzing UEFI with code coverage).

This is obviously just a bunch of notes/slides for a course. It's borderline useless for anybody not taking the course.

The word "hypervisor" always sounded so techo and cool to me!

No, that would be https://1000hv.seiya.me/en/ Easy mistake to make though, it is the 3rd such guide being posted in a week, definitely seems like the subject has a lot of traction.

Just wondering, what value do you get out of this? I used to like having a hardcopy of these kinds of things, especially when I used to have a much smaller monitor.

But these subjects evolve so fast, that having a bunch of .deadtrees lying around just become a nuisance.

If all I want is some form of archive to look back on later, a bunch of .md files seems perfect.

Not a 100% perfect solution, but you can click the little printer icon in the top right corner and then print to PDF from your browser.

Yeah, I'm not sure what people are getting from this...

If you already have the knowledge to understand the notes in the slides, it's probably pointless to you. If you don't, the slides make no sense at all since nothings explained.

What am I missing here that's so great ?

I used to work as a "Kernel/Hypervisor Engineer" at that big company that sells books. People from outside the tech always thought I'm some kind of supervisor's supervisor ;)

Welcome to Hypervisor 101 in Rust

This is a day long course to quickly learn the inner working of hypervisors and techniques to write them for high-performance fuzzing.

This course covers foundation of hardware-assisted virtualization technologies, such as VMCS/VMCB, guest-host world switches, EPT/NPT, as well as useful features and techniques such as exception interception for virtual machine introspection for fuzzing.

The class is made up of lectures using the materials within this directory and hands-on exercises with source code under the Hypervisor-101-in-Rust/hypervisor directory.

This lecture materials are written for the gcc2023 branch, which notionally have incomplete code for step-by-step exercises. Check out the starting point of the branch as below to go over hands-on exercises before you start.
