RHBA-2020:0711 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat OpenStack Platform 15.0 (Stein) for RHEL 8.

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:

• With this update, you can configure NUMA affinity for most neutron networks. This is useful to ensure that instances are placed on the same host NUMA node as the NIC that provides external connectivity to the vSwitch. This feature is available for networks that use a 'provider:network_type' of 'flat' or 'vlan' and a 'provider:physical_network' (L2 networks) or networks that use a 'provider:network_type' of 'vxlan', 'gre' or 'geneve' (L3 networks). (BZ#1696658)
• A new Compute (nova) parameter is now available, max_disk_devices_to_attach, which you can use to specify the maximum number of disk devices that can be attached to a single instance. The default is unlimited (-1). The following example illustrates how to change the value of max_disk_devices_to_attach to "30":

parameter_defaults:
ComputeExtraConfig:
nova::config::nova_config:
[compute]/max_disk_devices_to_attach:
value: '"30"' (BZ#1691040)

Changes to the python-novaclient component:

• With this update, the 'nova boot' command now validates the argument for the '--hint' option. This option expects a key-value argument. Previously, incorrectly formatted arguments were ignored silently, causing confusing behavior. (BZ#1756392)

Solution

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

form a working cloud computing environment.

• Technology Previews, Recommended Practices, and Known Issues.
• The channels required for Red Hat OpenStack Platform 15, including which

channels need to be enabled and disabled.
