Description Lukas Bezdicka 2020-06-19 22:35:06 UTC 
The upgrade prepare sets UpgradeLevelNovaCompute=auto which causes nova compute to throw error  nova.exception.DBNotAllowed: nova-compute attempted direct database access which is not allowed by policy

This is caused by other issue - https://bugs.launchpad.net/tripleo/+bug/1871482 but can be worked around by unsetting UpgradeLevelNovaCompute.
