But the bottom line is that we don't emit enough stuff from any of our tests to debug them from logs -- we're too used to using other methods. > And I don't understand what CFI is (and I don't rule out that > posibility) or I can't understand how checking indirect functions call > can make migration-test die without a single CFI error message? CFI (control flow inspection/validation/somesuch) adds checking along call paths, which may affect timing. This is almost certainly some sort of race condition. > Do we have a way to run on that image: > > ./tests/qtest/migration-test > > in a loop until it fails, and at least see what test is failing? Not as is, no. You'd have to create a new CI job, and for that you'll need advice beyond myself. r~
