I should rather say that the VM runs on a 9p root filesystem and it
doesn't use/mount any block devices or disk-based filesystems.

I have all the trinity logs for the crash if that's useful. I tried a
couple of runs with just the (at the time) in-progress syscalls but it
didn't turn up anything interesting. Otherwise it seems like a lot of
data to go through by hand.

The crashing child seems to have just started, though, if that's relevant:
