Wallaby Series Release Notes

14.2.0

New Features

• RHEL-8.3 kernel disabled the Intel “TSX” (Transactional Synchronization Extensions) feature by default as a preemptive security measure, but it breaks live migration from RHEL-7.9 (or even RHEL-8.1 or RHEL-8.2) to RHEL-8.3.

  Operators are expected to explicitly define the TSX flag in their KernelArgs for the compute role to prevent live-migration issues during the upgrade process.

  This also impacts upstream CentOS systems.

14.1.0

New Features

• Introducing the overcloud_service_status role. This role will hit the overcloud API for nova and cinder, retrieve the services and will trig a failure if one of these services are either down or deprecated. The original intent was to validate that nova-consoleauth was deleted after an update to RHOSP16.

14.0.0

Bug Fixes

• Existing resources “DISK_GB”, “MEMORY_MB”, “VCPU” were not considered to be available in case of custom_resource_class_val == False, also use correct types for resource comparison and required_count calculation.
