Virtual Time on a Deadline: Building an Open-Source Deterministic Hypervisor

Building a deterministic hypervisor is an incredibly difficult feat of engineering. Doing it as a bachelor’s thesis in just four months is even more so.
In this episode, David Wynn sits down with Peter Graugaard and Nicholas Kristensen, the creators of Dhyv—an open-source deterministic hypervisor they wrote for their undergraduate thesis at the Danish Technical University.
Inspired by Antithesis, these two software engineering students dove straight into CPU manuals, custom kernel patches, and the brutal realities of virtualizing time. Listen to how they survived the crunch, wrangled the…
