compute-tsx

RHEL8.x kernel flag for Compute nodes validation.

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.
