devstack guys met similar issue before, see https://bugs.launchpad.net/devstack/+bug/1812398. They handled this by removing any database configuration from nova compute conf.

Thanks for raising and for the Devstack hint. I have also seen this. Will try removing the DB conf.

Hi Mark, I've submitted a fix for this, https://review.opendev.org/#/c/660032/, but got stuck by some CI failure, I'm figuring out what's wrong with the patch.

    nova: Fix DBNotAllowed during compute startup

    backport: stein, rocky

    During startup of nova-compute, we see the following error message:

    Error gathering result from cell 00000000-0000-0000-0000-000000000000:
    DBNotAllowed: nova-compute

    This issue was observed in devstack [1], and fixed [2] by removing
    database configuration from the compute service.

    This change takes the same approach, removing DB config from nova.conf
    in the nova-compute* containers.
