Use FIPS VPN workflow for IBM Z TechPreview conformance-parallel jobs

[ibm-adarsh]

Summary

• Switch IBM Z (s390x) TechPreviewNoUpgrade conformance-parallel periodics to openshift-e2e-libvirt-vpn-fips and set FIPS_ENABLED: "true" for OCP 4.23, 5.0, and 5.1
• Jobs updated:
  • ocp-e2e-ovn-techpreview-multi-z-z (nightly-4.23)
  • ocp-e2e-ovn-techpreview-remote-libvirt-multi-z-z (nightly-5.0, nightly-5.1)
• Serial TechPreview and Power jobs are unchanged

Test plan

• Confirm only the three multiarch nightly configs above changed
• /pj-rehearse one or more of the affected periodics, or /pj-rehearse skip if appropriate
• Verify install enables FIPS and the fips-check pre-step runs via the FIPS VPN workflow

Summary by CodeRabbit

The PR updates three IBM Z (s390x) TechPreviewNoUpgrade conformance-parallel nightly jobs for OCP 4.23, 5.0, and 5.1. These jobs now use the openshift-e2e-libvirt-vpn-fips workflow and set FIPS_ENABLED: "true" to validate FIPS installation and execution.

Serial TechPreview and Power jobs remain unchanged.

Hi @ibm-adarsh. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Walkthrough

Three multiarch OVN TechPreview jobs now enable FIPS and use the FIPS-specific libvirt VPN workflow.

Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (1 error)

Check name	Status	Explanation	Resolution
No-Sensitive-Data-In-Logs	❌ Error	The three changed jobs now invoke fips-check, which logs each cluster node name via ${nodes[i]}; node names may expose internal hostnames.	Redact, hash, or omit node names in fips-check status messages before enabling this workflow for these jobs.

✅ Passed checks (14 passed)

Check name	Status	Explanation
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The patch changes only three YAML workflow/env entries and adds no Ginkgo test titles or dynamic test-name expressions.
Test Structure And Quality	✅ Passed	The PR changes only three YAML ci-operator configs and adds no Ginkgo test code, so the listed test-quality criteria are not applicable.
Microshift Test Compatibility	✅ Passed	The pull request changes only three YAML CI configurations and adds no Ginkgo tests or MicroShift-incompatible API usage.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR changes only three YAML CI configurations and adds no Ginkgo tests or test bodies, so the SNO multi-node compatibility check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff changes only three CI YAML files, adding FIPS_ENABLED and selecting an existing FIPS workflow; it adds no deployment, controller, or scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The HEAD patch changes only three YAML configuration files and no Go or OTE source, so it introduces no process-level stdout writes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The pull request changes only three CI YAML files; it adds no Ginkgo tests or networking code, so this compatibility check is not applicable.
No-Weak-Crypto	✅ Passed	The commit adds only FIPS_ENABLED and an existing FIPS workflow reference; no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons occur.
Container-Privileges	✅ Passed	The diff changes only three CI YAML files and adds FIPS settings/workflow names; no privileged, host namespace, SYS_ADMIN, root, or allowPrivilegeEscalation declarations were added.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly summarizes the main change: applying the FIPS VPN workflow to IBM Z TechPreview conformance-parallel jobs.
