    Compute TSX 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.
