Hey Matthieu,

Yeah, that's exactly the first approach I'm taking here :-). I'm glad we're on the same page. And thanks for providing detailed instructions about virtme, those were helpful to unblock me.

So, in the ideal world we would have a self-contained test that doesn't require third-party software that's not packaged in Ubuntu, but honestly, I'm fairly happy to just remove Docker from the equation here. virtme is just a wrapper on top of qemu, and the entrypoint.sh script doesn't install any extra package from an unknown repository.

Right now, I'm trying to reproduce the problem with qemu from Jammy (I managed to reproduce it using Mantic). I'm a little bit puzzled to see that the qemu crashed quicker on Mantic (I've been running the test on Jammy for more than 2 hours now, and it still hasn't crashed). Anyway, I'll leave it running overnight.

Another thing that's concerning is the difference in the codebase from qemu 6.2 (the version from Jammy) and 8.x. I started backporting the upstream patches into Jammy and noticed that there are non-trivial conflicts to be solved.

I apologize for the slow progress here. I'm spread thin across many tasks so I have to timebox my work on this bug.

Hopefully I'll have good news tomorrow.
