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 or update process.
We now introduce this validation in tripleoclient to ensure
early failure.
