RHBA-2017:2652 - 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:

• Cause:

The "nova hypervisor-stats" command does not take into account deleted nodes.

Consequence:
The values output by "nova hypervisor-stats" is not accurate when some compute nodes are deleted.

Fix:
Update the query used to grab the stats to avoid deleted compute nodes.

Result:
The ouput of the "nova hypervisor-stats" command now only take into account relevant compute nodes. (BZ#1458190)

• Cause:

When using DPDK ports, the MTU passed by Neutron to Nova is not take into account.

Consequence:
The ports are configured to a default value which may not match what is expected (for example,jumbo frames). (BZ#1468620)
