While it's a tough call to remove a useful test that from the tree because it may fail every 1/100th time (or so), having human attention drawn to known issues is very bad for humans and for the projects they manage. As a compromise solution, this marks tests that are known to have issues, or that exercises known issues in QEMU or other components, and excludes them from the entry point. As a consequence, tests marked as "flaky" will not be executed as part of "make check-acceptance". Because such tests should be forgiven but never be forgotten, it's possible to list them with (assuming "make check-venv" or "make check-acceptance" has already initiatilized the venv): $ ./tests/venv/bin/avocado list -t flaky tests/acceptance The current list of tests marked as flaky are a result of running the entire set of acceptance tests around 20 times. The results were then processed with a helper script[1]. That either confirmed known issues (in the case of aarch64 and arm)[2] or revealed new ones (mips). This also bumps the Avocado version to one that includes a fix to the parsing of multiple and mix "key:val" and simple tag values.
