RHBA-2015:1637 - Bug Fix Advisory

Topic

Updated OpenStack Orchestration packages that resolve various issues are
now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo)
for RHEL 7.

Description

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

• OpenStack Orchestration service

OpenStack Orchestration (heat) is a template-driven engine used to specify
and deploy configurations for Compute, Storage, and OpenStack Networking.
It can also be used to automate post-deployment actions, which in turn
allows automated provisioning of infrastructure, services, and
applications. Orchestration can also be integrated with Telemetry alarms to
implement auto-scaling for certain infrastructure resources.

Changes to the openstack-heat component:

• Previously, remote procedure call messages would take longer than the configured default, triggering a mishandled exception case. This would obscure the correct traceback for the timeout due to a traceback in the exception handling code, making the error more difficult to diagnose. With this update, the exception handling code has now been revised so that a remote procedure call response timeout is raised, and timeouts are less frequent due to a higher threshold. (BZ#1231825)

Solution

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