Changes: v2: Improve coding to avoid code duplication The function FeatureTests.disable_libvirt_error_logging only removes the error message that will be displayed on the console. Libvirt also logs errors on messages log. To avoid flood messages log with metadata errors, it will be verified manually if the xml has the tag.
