- 25 vrtManager test modules configured settings themselves when Django had none (MAC_OUI, and in test_network_ip a fake django module): under manage.py test settings are always configured, so it never ran. - webvirtcloud/tests/test_common_tags.py tested no tag: it fetched an unknown URL, as test_error_pages and test_logging already do. - .gitignore covers the parallel runs' test_db_N.sqlite3 files too.
