Walkthrough

The nightly release configurations shard vSphere TechPreview serial jobs across releases 4.22, 4.23, 5.0, and 5.1. Release 4.23 also adds scheduled vSphere zones TechPreview jobs. Release verification entries map the two shards to separate Prow jobs.

Changes

vSphere TechPreview sharding

Layer / File(s)	Summary
Nightly test configuration ci-operator/config/openshift/release/openshift-release-main__nightly-4.22.yaml, ci-operator/config/openshift/release/openshift-release-main__nightly-4.23.yaml, ci-operator/config/openshift/release/openshift-release-main__nightly-5.0.yaml, ci-operator/config/openshift/release/openshift-release-main__nightly-5.1.yaml	Existing vSphere TechPreview serial jobs now use two shards. Release 4.23 adds scheduled vSphere zones TechPreview parallel and serial conformance jobs.
Release verification mapping core-services/release-controller/_releases/**/*.json	Each release replaces the single vSphere OVN TechPreview serial verification entry with 1of2 and 2of2 entries mapped to separate Prow jobs. The entries remain optional, and the private entries remain disabled.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to c90bd

vSphere TechPreview serial verification is split into two separately mapped shards across the affected releases. The supplied configuration evidence shows consistent shard mappings, with no current merge-readiness risk identified.
