Role documentation

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.

Role documentation

undercloud-ipa-server-check

Verify that the IPA server has the right permissions and ACI.

This validation is relevant for systems where TLS Everywhere is enabled.

A new ACI is needed on the FreeIPA server to ensure that certificates with IP SANs can be issued. This ACI will be delivered by default from FreeIPA 4.8.5.

In addition, a new permission is needed to add DNS zones for tripleo-ipa. This permission is an addition to the current permissions for the Nova Host Manager role.

This validation confirms that the new permission and ACI are present.
