charset="utf-8" From: Thomas Huth We've got this nice vmstate-static-checker.py script that can help to detect screw-ups in the migration states. Unfortunately, it's currently only run manually, so there could be regressions that nobody notices immediately. Let's run it from a functional test automatically so that we got at least a basic coverage in each CI run.
