15.1.0

15.0.0

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.
