(RHSA-2019:2622) Moderate: openstack-nova security and bug fix update

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.

Security Fix(es):

• openstack-nova: Nova server resource faults leak external exception details (CVE-2019-14433)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

• Previously, the heal info cache periodic task used the network info cache to heal the network info cache. If the cache was corrupted or missing, the heal info cache task could not heal the network info cache.

With this update, the heal info cache uses VM data from Neutron when healing the network info cache. (BZ#1703225)

• Previously, evacuation, migration, and resize operations took unnecessarily long to process on destination hosts with a large number of network interfaces. This was due to the my_ip configuration printing a warning when it did not find any of the host interfaces.

With this update, the my_ip configuration occurs only once during host initialization. This reduces the time it takes to process migrations, evacuations, and resize operations. (BZ#1732879)
