Some many years ago there was a commercial product called Jinx debugger [1]. I think I only ever got to kick the tires and find out I couldn't get the hypervisor to run on my machine.

Good to see Meta making more practical Open Source tools like this (and BOLT).

There’s a bit of shared lineage there. Joseph Devietti and I started working in this area together around 2015. And Joe had worked on the deterministic dOS at UW during his PhD (which led to Jinx).

Another related effort is antithesis.com which also seems to use a hypervisor approach rather than Hermits Linux-syscall-API level approach.
