From 002eec951f336b07ef3a7f277e9c0fe6aae9a952 Mon Sep 17 00:00:00 2001 From: Mark Goddard Date: Mon, 20 May 2019 10:17:32 +0100 Subject: [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.
