Comment 1 for bug 1880669

Please give us more details by filling out the bug report template [1] when you reporting a bug.

Based on the exception type 'oslo_db.exception.DBError' I suspect you have a some problem with your database serer or nova database configuration. But without the actual nova logs I cannot say more.

I'm marking this bug Incomplete. Please set it back to New when you provided the necessary information
