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.
