RHBA-2017:2994 - Bug Fix Advisory

Topic

Updated OpenStack Compute 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 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:

• This fix updates the white list for certain SSH commands used during instance migration. (BZ#1472723)
• Compute would not detach a volume from the live instance domain if it previously detached from the persistent instance domain. It also reported success if another attempt to detach the volume was made. Consequently, the volume could be attached to another live instance domain at the same time, which could lead to data corruption. This fix adds logic to check for this behavior. Any attempt to detach a volume from the live instance domain only reports success when the volume has been really detached. (BZ#1476370)

Solution

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