I noticed this tonight and reported this bug: https://bugs.launchpad.net/nova/+bug/1739517 This fails at a decent rate (67 hits in 7 days), check and gate queues and on master and stable branches, which is the really weird thing. Seems to only be in the TestNovaMigrationsMySQL job. I'm not sure what to make of the actual failure though. This is also showing up over a week, so it's longer than we've had this change: https://review.openstack.org/#/q/I6bf0fa19b72887803e77b66698587c2108c9372a I'm not sure what to make of the actual failure. -- Thanks, Matt
