We'll get a NoValidHost either way but this is better than the traceback with the TypeError in it. ** Affects: nova Importance: Low Assignee: Matt Riedemann (mriedem) Status: Triaged ** Affects: nova/train Importance: Undecided Status: New ** Tags: scheduler -- You received this bug notification because you are a member of Yahoo!
