 If you want to prevent killing virtual machine of a test on a failure detected in the log before the installation finishes (eg `Traceback` indicated in the log) it is possible to configure monitored messages in the [log monitor](/scripts/launcher/lib/log_monitor/log_handler.py) file.

+You can run the tests in dry-run mode using `--dry-run` option. It can be used to see which tests would be actually run and the kickstarts with substitutions applied. Or to get the list of packages composing the installer image.
 
 We are tracking the test suite issues and flakes in the repository issues. There is a [script](/scripts/classify-failures) to detect such known issues from test logs.
