RHBA-2019:0087 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve various issues are now
available for Red Hat OpenStack Platform 13.0 (Queens) 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:

• This feature allows you to create instances with trusted SR-IOV virtual

functions (VFs), such as changing the MAC address of the VF and enable
promiscuous mode directly from the guest instance. These functions help you
configure failover VFs for instances directly from the instance.

To configure trusted mode for VFs, you first set the `trusted` value of the
`[pci] passthrough_whitelist` JSON configuration option in nova.conf. You
then create the port with the `trusted=true` attribute in the binding
profile. Make sure that the `vnic-type` attribute has the `hw_veb` or
`direct` values. (BZ#1636395)

• Previously, the CPU thread policy applied also to isolated emulator

threads. This caused a collision of CPU core consumption if you set both
`hw:emulator_threads_policy` and `hw:cpu_thread_policy` properties in the
instance flavor.

This bug fix separates the policies so that isolated emulator threads now
consume a single host core for each instance, regardless of the CPU thread
policy of the instance. (BZ#1608105)

Solution

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