Bug description:
  Steps to reproduce
  ==================

  Starting with a cloud running the Queens release, upgrade to Rocky.

  Create a flavor that cannot fit on any compute node, e.g.

  openstack flavor create --ram 100000000 --disk 2147483647 --vcpus
  10000 huge

  Then create an instance using that flavor:

  openstack server create huge --flavor huge --image cirros --network
  demo-net

  Expected
  ========

  The instance fails to boot and ends up in the ERROR state.

  Actual
  ======

  The instance fails to boot and gets stuck in the BUILD state.

  Workaround
  ==========

  On the controller, perform a nova DB sync:

  docker exec -it nova_api nova-manage db sync

  Despite this making no changes to the database (checked with
  mysqldump), it seems to 'fix' nova. New instances created using the
  'huge' flavor will go to the ERROR state.
