RHBA-2020:2154 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat OpenStack Platform 16.0 (Train) for Red Hat Enterprise Linux (RHEL) 8.1.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

• OpenStack Compute service

OpenStack Compute (nova) launches and schedules large networks of virtual
machines, creating a redundant and scalable cloud computing platform.
Compute provides the software, control panels, and APIs required to
orchestrate a cloud, including running virtual machine instances and
controlling access through users and projects.

Changes to the openstack-nova component:

• This update fixes a bug where where list operations failed to show instances after an upgrade to the Stein release of OpenStack.

In deployments with large databases, this bug corrupted instance records, preventing the instances from appearing in list operations.

Support for upgrades to Red Hat OpenStack Plaform (RHOSP) 16.0 begins with the release of RHOSP 16.1.

RHOSP 16.1 and higher include this fix, so the bug will not affect RHOSP upgrades. (BZ#1801364)
