Upstream bug: https://bugs.launchpad.net/nova/+bug/1835400 Upstream gerrit: https://review.opendev.org/#/c/669190/ --- Additional comment from Mikel Olasagasti on 2019-10-11 08:04:24 UTC --- Changing os_distro=rhel7.5 with to os_distro=rhel, os_version=7.5 seems to be a valid workaround. Changing to OSP13 as it is also affecting OSP13.
