RHBA-2020:3572 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat OpenStack Platform 16.1 (Train) for Red Hat
Enterprise Linux (RHEL) 8.2.

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:

• OSP 16.0 introduced full support for live migration of pinned instances. Due to a bug in this feature, instances with a real-time CPU policy and more than one real-time CPU cannot migrate successfully. As a result, live migration of real-time instances is not possible. There is currently no workaround. (BZ#1861363)
