test pr chnages

[mohitsharma-web]

What this PR changes (practical impact)

This PR updates the OpenShift CI configuration for the multiarch repository's nightly upgrade job matrix that validates upgrades from nightly 4.20 → nightly 4.21. It adjusts test environment resource sizing and DNS/workflow settings for heterogeneous and libvirt-based upgrade jobs used by CI.

• Affected repo: openshift/multiarch (ci-operator job configuration)
• Affected CI area: nightly multi-architecture upgrade tests (ci-operator config for upgrade validation)

Key changes

• GCP heterogeneous upgrade (ocp-e2e-upgrade-gcp-ovn-multi-x-ax)

  • Increased ADDITIONAL_WORKER_VM_TYPE from t2a-standard-2 → t2a-standard-4 (more ARM worker resources for mixed-arch upgrade testing).
  • OCP_ARCH remains amd64 and the job continues to use the openshift-org-gcp cluster_profile.

• GCP single-arch ARM upgrade (ocp-e2e-upgrade-gcp-ovn-multi-a-a)

  • COMPUTE_NODE_TYPE is set to t2a-standard-4 for arm64 compute nodes.

• libvirt/remote upgrade jobs

  • The libvirt s2s UPI upgrade job (ocp-ovn-remote-s2s-libvirt-multi-p-p) now sets USE_EXTERNAL_DNS: "true" and uses the openshift-e2e-libvirt-upi workflow.
  • The separate libvirt VPN test (ocp-ovn-remote-libvirt-multi-z-z) also sets USE_EXTERNAL_DNS: "true".
  • A previously-present capability entry (power-s2s-dns) was removed from the s2s/libvirt entries.

• Metadata

  • zz_generated_metadata.variant set to nightly-4.21-upgrade-from-nightly-4.20 to identify this upgrade scenario.

Other notes

• Changes are limited to CI job YAML (no code/public API changes).

Hi @mohitsharma-web. 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.

Regular contributors should join the org to skip this step.

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

Updated multi-arch OpenShift nightly-upgrade CI config: changed the ARM additional worker VM from t2a-standard-2 to t2a-standard-4 and removed COMPUTE_NODE_REPLICAS; removed power-s2s-dns capability from a libvirt entry; added USE_EXTERNAL_DNS: "true", set workflow to openshift-e2e-libvirt-upi, and added variant metadata.
