RHBA-2019:0923 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat OpenStack Platform 10.0 (Newton) for RHEL 7.

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:

• Previously, due to an update that made memory allocation pagesize aware, you cannot oversubscribe memory for instances with NUMA topologies.

With this update, memory oversubscription is disabled for all NUMA topology instances, including implicit NUMA topologies, such as hugepages or CPU pinning. (BZ#1664702)

Solution

Before applying this update, ensure all previously released errata relevant
to your system have been applied.

Red Hat OpenStack Platform 10 runs on Red Hat Enterprise Linux 7.6.

The Red Hat OpenStack Platform 10 Release Notes contain the following:

• An explanation of the way in which the provided components interact to

form a working cloud computing environment.

• Technology Previews, Recommended Practices, and Known Issues.
• The channels required for Red Hat OpenStack Platform 10, including which

channels need to be enabled and disabled.
