name: RHEL8.x kernel flag for Compute nodes validation
|
|
description: |
|
|
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.
