RHBA-2017:0319 - 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.

With this release, OpenStack Compute is now re-based to upstream version
14.0.3. This applies several fixes and enhancements, including:

• Serial ports are now reserved on destination hosts prior to any

attempts with live migration. This prevents any possible port
conflict errors, which would result in a failed migration.
(BZ#1396867)

• With this update, the Compute service will now always attempt to

clean up after a generic error is thrown while attempting to spawn
an instance. This help prevent the Compute service from leaking
resource services (for example, VIFs) during generic errors. In
previous releases, the Compute service only performed a resource
cleanup on a compute node after certain failures occurred during
instance spawning attempts.
(BZ#1354601)

• With this update, XML generated by the Compute service is now fully

compatible with libvirt 2.0.0. Instances spawned prior to this
update will need to have their XML regenerated through a hard
reboot, rebuild, or unshelve operation in order to be compatible.
(BZ#1408464)

• The `Instance.pci_devices` field is nullable, but previously the

`get_instance_pci_devs()` function did not account for that
possibility. If it was passed to an instance from an older deployment
(for example, Red Hat OpenStack Platform 9) with no `pci_devices`,
it would crash trying to iterate `None` as a list.

This issue also affected live migration triggered as part of the
upgrade workflow; specifically, attempting to live migrate guests
from Red Hat OpenStack Platform 9 hosts to Red Hat OpenStack
Platform 10 hosts. The issue is now resolved in Red Hat OpenStack
Platform 10 as of this update.
(BZ#1403380)
