Public bug reported:

As of the following commit:
https://github.com/openstack/nova/commit/8a7b95dccdbe449d5235868781b30edebd34bacd
our nova-compute service on the seed node is throwing DBErrors.  If I
reset my Nova tree to the previous commit and downgrade the database to
232 then I am able to use nova successfully again.  With that commit all
boots fail with a No hosts found message, presumably related to the
following messages in the nova-compute log:
