Title:
nova api_db sync fails remove unused build_requests columns
Status in OpenStack Compute (nova):
Expired
Bug description:
Description
===========
During an upgrade from xena to yoga, I followed upgrade steps using
openstack-ansible to upgrade nova. During this time i was met with the
following log message:
alembic.runtime.migration [-] Running upgrade d67eeaabee36 ->
b30f573d3377, Remove unused build_requests columns
And the python exception:
/openstack/venvs/nova-25.2.1.dev3/bin/nova-manage api_db sync
Modules with known eventlet monkey patching issues were imported prior to
eventlet monkey patching: urllib3. This warning can usually be ignored if the
caller is only importing and not executing nova code.
An error has occurred:

[SQL: ALTER TABLE build_requests DROP COLUMN vm_state]
Steps to reproduce
==================
I was able to reproduce this bug by dropping the entire nova database,
creating a nova database and running
/openstack/venvs/nova-25.2.1.dev3/bin/nova-manage api_db sync
Expected result
===============
I expect nova-manage to test if build_requests is present before attempting
to alter/drop it.
Actual result
=============
The python module reports the exception mentioned above.
Environment
===============
Nova: 25.0.2
Openstack: Yoga
Mariadb: 10.6.11
Hypervisor: libvert+kvm
Storage Type: ceph
Network: Neutron
