Working on Mini Operating Systems for Testing of Virtualization Stacks at Cyberus

Usually, I do not just forward people to other blogs. But the other day, I published an interesting article on my company’s* tech blog about testing virtualization stacks using mini operating systems. Here’s the excerpt:

Testing and debugging erroneous behavior by a guest under a virtualization stack is hard and difficult. By leveraging multiple mini operating system kernels, we can investigate issues related to complicated topics, such as never delivered interrupts, with a precise focus on where to look at. For that, we created our internal Cyberus Guest Tests that we present in this blog post.

Feel free to check it out! Personally, I think this topic absolutely cool, interesting, and important. Our Cyberus Guest tests are for sure a cool project. I’m very glad I can be a part of the project and currently maintain it.

You can also find the source code on GitHub.
