Hard lesson to learn. Tests are not as deterministic as we would like them
to be. For my part, I tend to re-run qemu tests before I report failures
because some failures are sporadic. After a couple of years I know the
usual suspects, which helps. Adding an automatic retry mechanism might
be useful.
