nova, oslo.db or SQLAlchemy bug?
Hello,
SQLAlchemy 1.4 requested some adaptations in various places (oslo.db, nova, cinder etc).
Without digging into your issue, oslo.db 8.6.0 at least is required to support this version of SQLAlchemy [1].
Also you should notice that various patches are required on Nova and other services too [2][3][4][5]. I think that the services deliverables (nova, cinder, etc) should be released to propagate their fixes more widely and surely fix your context.
For further reading please have a look to [6].

Please note that Nova on stable/wallaby does not officially support SQLAlchemy 1.4 as per the global upper constraint in requirements https://github.com/openstack/requirements/blob/stable/wallaby/upper-constrai...
Cheers, gibi

I understand from reply (not to the list) from Balazs Gibizer that Wallaby needs SQLAlchemy < 1.4
Without digging into your issue, oslo.db 8.6.0 at least is required to support this version of SQLAlchemy [1].
Yes, Wallaby only oslo.db = 8.5. 8.6 is for next release I understand now
Thanks both for the clarification. I'll downgrade SQLAlchemy and report later if I get Wallaby running
