We've seen that a few of the unit test cases occasionally fails because of timeout.
I've not yet identified the specific test case affected by this problem.
Example build:
https://zuul.opendev.org/t/openstack/build/c468469e82364512b5383640c373f88e
Example output:
cinder.tests.unit.backup.drivers.test_backup_google.GoogleBackupDriverTestCase.test_backup_backup_metadata_fail2
