Hi Boris, Roman, Victor (oslo-incubator db maintainers), Last night I stumbled across bug https://launchpad.net/bugs/1272500 in nova, which says the issue has been fixed in the latest oslo-incubator code. So I ran: ./update.sh --base nova --dest-dir ../nova --modules db.sqlalchemy https://review.openstack.org/#/c/71191/ And that appeared to fix the specific issues I was seeing from Bug 1272500, but it introduced some new failures. I would like to get nova unit test working with sqlite 3.8.2-1 if possible. How can this situation be resolved? best, Joe
