OCPBUGS-74510: Removed VSphereMultiDisk feature gate

[vr4manta]

OCPBUGS-74510

Changes

• Removed usages of VSphereMultiDisk feature gate
• Updated tests to assume GA of feature gate

Notes

Removed VSphereMultiDisk feature gate now that it has been GA for several releases

Summary by CodeRabbit

• New Features

  • vSphere machines now support multiple data disks by default, without requiring a separate feature toggle.
  • Data disk validation is consistently applied, including size, naming, and provisioning constraints.

• Bug Fixes

  • Removed the previous configuration restriction that blocked additional disks when the feature toggle was disabled.
  • Updated validation and end-to-end coverage to reflect the default multi-disk behavior.

Walkthrough

The VSphereMultiDisk feature gate was removed from registration, defaults, reconciliation, and webhook validation. vSphere data disks are now processed and validated without the gate. Unit and end-to-end tests were updated.

Changes

VSphereMultiDisk gate removal

Layer / File(s)	Summary
Remove feature-gate registration and defaults cmd/machineset/main.go, cmd/vsphere/main.go, pkg/operator/..., pkg/util/testing/testing.go	Command and operator configuration no longer registers or enables VSphereMultiDisk.
Process and validate vSphere data disks unconditionally pkg/controller/vsphere/reconciler.go, pkg/webhooks/machine_webhook.go, pkg/webhooks/machine_webhook_test.go, test/e2e/vsphere/machines.go	Reconciliation and webhook validation no longer require VSphereMultiDisk. Related tests no longer configure the gate or require its test label.

🚥 Pre-merge checks | ✅ 13 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Test Structure And Quality	⚠️ Warning	The Ginkgo vSphere tests use bare error assertions and delete Machines/MachineSets only inline, so a failed step can leak resources; repository patterns use DeferCleanup for this case.	Add DeferCleanup or AfterEach cleanup immediately after each resource is created, and add operation-specific messages to all cluster-operation assertions.
Single Node Openshift (Sno) Test Compatibility	⚠️ Warning	The PR removes the feature-gate label from an existing serial vSphere suite whose tests add/remove machines and verify node counts; no SNO guard exists.	Single Node OpenShift (SNO) compatibility notice: verify this serial test with /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-aws-ovn-single-node-serial, or add a SNO skip guard.

✅ Passed checks (13 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly and concisely identifies the main change: removal of the VSphereMultiDisk feature gate.
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	All changed Ginkgo titles in test/e2e/vsphere/machines.go are static string literals; the PR only removes a static feature-gate label from Describe.
Microshift Test Compatibility	✅ Passed	The PR adds no Ginkgo tests; it only removes a feature-gate label from an existing Describe. Its existing It test has [apigroup:machine.openshift.io].
Topology-Aware Scheduling Compatibility	✅ Passed	The patch only removes the VSphereMultiDisk gate and updates validation/tests; the diff adds no affinity, topology spread, replica, node selector, toleration, or PDB constraints.
Ote Binary Stdout Contract	✅ Passed	cmd/machine-api-tests-ext/main.go has no process-level stdout write; fmt.Printf calls are in vSphere helpers invoked from It bodies, which the check excludes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The PR adds no new Ginkgo tests. It only removes the VSphereMultiDisk label from an existing Describe block, with no new IPv4 assumptions or external connectivity.
No-Weak-Crypto	✅ Passed	The patch only changes feature-gate and vSphere disk validation logic; added lines and all changed files contain no MD5, SHA1, DES, RC4, Blowfish, ECB, or secret-comparison code.
Container-Privileges	✅ Passed	The PR changes only Go files and adds no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, root, or allowPrivilegeEscalation settings in container/Kubernetes manifests.
No-Sensitive-Data-In-Logs	✅ Passed	The PR adds no logging calls or sensitive log fields. The diff removes the VSphereMultiDisk status log, and added code contains no password, token, API key, PII, or hostname logging.
