The explanation sounds somewhat implausible to me. AVOCADO_TIMEOUT_EXPECTED should be for jobs where we are not sure whether the job really finishes in time, e.g. when compiling QEMU with debug flags enabled, and not for jobs that simply run a little bit longer (in the latter case, it would be enough to simply bump the timeout setting a little bit if necessary). So did you check whether you really run into timeout issues here when compiling QEMU with debug flags? Anyway, if you add AVOCADO_TIMEOUT_EXPECTED, then I think you don't need GITLAB_CI anymore, since we certainly don't set AVOCADO_TIMEOUT_EXPECTED in the gitlab CI. Thomas

Correct we won't run AVOCADO_TIMEOUT_EXPECTED on GitLab CI. Note however GITLAB_CI and AVOCADO_TIMEOUT_EXPECTED are not orthogonal. See docs/devel/testing.rst: AVOCADO_TIMEOUT_EXPECTED ... Even though the timeout can be set by the test developer, there are some tests that may not have a well-defined limit of time to finish under certain conditions. For example, tests that take longer to execute when QEMU is compiled with debug flags. Therefore, the ``AVOCADO_TIMEOUT_EXPECTED`` variable has been used to determine whether those tests should run or not. GITLAB_CI A number of tests are flagged to not run on the GitLab CI. Usually because they proved to the flaky or there are constraints on the CI environment which would make them fail. Personally I run the Avocado tests on a daily basis without AVOCADO_TIMEOUT_EXPECTED, but certainly set it before posting a pull request.

This test is exceptionally heavyweight (nearly 330s) compared to the two (both endians) TuxRun baseline tests which complete in under 160s.
