RHBA-2016:0283 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) 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 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, a race condition would be encountered when instances were assigned several network interfaces, causing some interfaces to not be correctly initialized during boot time, or removed during the build process. With this update, a lock has now been added to the method that maintains the network interfaces for instances, resolving the race condition so that you can correctly boot instances with multiple network interfaces or rebuild instances without losing any network interfaces. (BZ#1279505)
• Previously, the code responsible for initializing live migration of instances did not handle some exceptions that could be raised. If an unexpected exception was raised, the code could not handle it, and the instance would enter an unpredictable state. With this update, the code has been improved to handle unexpected exceptions and convert them to a knowing MigrationError's exception, which allows instances that experience unexpected exceptions to enter an error state, which is expected. The code now also rolls back any actions. (BZ#1292503)
