Summary

Promote the OSStreams feature gate from TechPreviewNoUpgrade to Default for the Hypershift cluster profile. This enables RHEL 9/10 dual-stream support for hosted control planes by default.

What changed

features/features.go: Added inDefault(), inOKD() to the Hypershift profile enable line for FeatureGateOSStreams

CRD manifests consolidated: per-profile CRDs (-Hypershift-*, -SelfManagedHA) merged into single profile-less CRDs since OSStreams is now enabled across all profiles

Feature gate payload manifests updated: featureGate-4-10-Hypershift-Default.yaml and featureGate-4-10-Hypershift-OKD.yaml now list OSStreams as enabled

Why now

The MCO ExternalTopologyMode guard that previously excluded HyperShift from OSImageStream processing was removed in openshift/machine-config-operator#6308. HyperShift now writes 99_osimagestream.yaml into the MCC template directory (openshift/hypershift#8792), allowing MCO bootstrap to discover and serve the correct OS stream. The prerequisite conversations mentioned in #2849 have been resolved.

📝 Walkthrough

Walkthrough

OSStreams is enabled in the feature registry and Hypershift Default and OKD feature-gate manifests. The feature table places OSStreams later with all feature-state columns enabled. MachineConfigPool and OSImageStream CRDs add IBM Cloud Managed release annotations. Hypershift-specific CRD manifests are removed.

Suggested reviewers: everettraven

Mergeability Score: 🟡 Moderate · up to 89478

The feature matrix currently advertises OSStreams as enabled for SelfManagedHA profiles even though this change promotes it only for Hypershift, which could mislead users about supported configurations. The matrix should be regenerated before merging.

PR Summary by Qodo

Promote OSStreams feature gate to Default/OKD for HyperShift and consolidate CRDs

✨ Enhancement ⚙️ Configuration changes 📝 Documentation 🕐 40+ Minutes

AI Description

• Enable OSStreams by default for HyperShift Default/OKD feature sets (RHEL 9/10 dual-stream).
• Consolidate per-profile MachineConfigPool/OSImageStream CRDs into shared, profile-less manifests.
• Update HyperShift feature gate payload manifests and feature gate documentation accordingly.

  E --> E2["MachineConfigPool CRD"]

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep per-profile CRD variants (no consolidation)

➕ Lower risk if any downstream tooling implicitly depends on the per-profile CRD filenames or release annotations
➖ Continues duplication/maintenance burden across Hypershift feature sets
➖ Makes future schema changes more error-prone due to multiple generated copies

2. Gate CRD inclusion instead of consolidating (retain shared CRD but conditional release annotations)

➕ Preserves a single CRD source while still allowing differentiated payload composition if needed later
➖ Adds complexity to release annotation logic and testing matrix
➖ Still requires careful reasoning about which profiles receive which CRDs

Recommendation: The PR’s approach (promote OSStreams for HyperShift Default/OKD and remove redundant per-profile CRD copies) is the best long-term maintenance choice, assuming no consumers depend on the removed per-profile CRD filenames. Review should focus on verifying payload composition remains correct for all feature sets and that the shared CRDs include the required release annotations (e.g., ibm-cloud-managed/self-managed-ha) previously covered by the profile-specific copies.

With MCO PR openshift/machine-config-operator#6308 merged and the OSStreams feature gate promoted to Default for Hypershift (openshift/api#2950), the MCO can now process OSImageStream during bootstrap.

@jparrill I'm trying to find any testing of the osstreams feature on hypershift, I may be holding sippy wrong but filtering to toplogy:external gives me no results, any idea?

jparrill · 2026-07-24T11:03:50Z

Hey @JoelSpeed Yes they are, but it's not testing the feature properly, let me explain:

Until now we've hardcoded the output of the E2E in order to not break our pipelines
Yesterday a PR was merged on MCO to serve the right RHEL Version to hypershift
I have another PR which removes that hardcoded part from the code and E2E (CNTRLPLANE-3871: resolve RHEL stream dynamically for boot images hypershift#9099)

From your question and the email about stabilization I assume we need at least 14 consistent runs of the e2e (without things hardcoded), am I right?

If that so, we will need the other PR merged before this move ahead. If you know any other way to move on, please let me know.

JoelSpeed · 2026-07-24T11:09:00Z

From your question and the email about stabilization I assume we need at least 14 consistent runs of the e2e (without things hardcoded), am I right?

This is the general expectation yes. We want to see data that shows that the feature is stable before we consider it promoted. Is the dynamic resolution of the boot image gated behind this feature gate?

… on hosted clusters in e2e-v2-aws Set GUEST_FEATURE_SET=TechPreviewNoUpgrade so the hosted cluster MCO processes OSImageStream manifests. This is needed to validate the dual-stream RHEL 9/10 feature (OSStreams) in HyperShift E2E tests. This is a temporary measure: once the E2E tests pass consistently, we can graduate the OSStreams feature gate to Default for Hypershift (openshift/api#2950), after which GUEST_FEATURE_SET can be reverted back to Default since OSStreams will be active without TechPreview. The management cluster HO already runs with TechPreview via TECH_PREVIEW_NO_UPGRADE, but the hosted cluster was using Default, causing the MCO to ignore the 99_osimagestream.yaml manifest written by the ignition-server.

OSStreams periodic job stabilization analysis

The temporary periodic job periodic-ci-openshift-hypershift-release-5.0-periodics-e2e-v2-aws-techpreview-osimagestream (registered via openshift/release#82438, running with dynamic resolution after openshift/hypershift#9099) has been running 4x/day since Aug 3.

Current streak: 25 consecutive passes

Period	Result	Count
2026-08-03 18:00 → 2026-08-06 00:00	Failures (initial stabilization)	10 runs
2026-08-06 06:00 → 2026-08-12 06:00	All passing	25 runs

The initial failures (Aug 3–5) correspond to the period right after the job was first registered — before all pieces had fully landed. Since Aug 6, every run (6+ days, 4x/day) has passed without interruption.

This exceeds the 14 consecutive passing runs expectation discussed above.

Latest run: 2026-08-12 06:00 UTC

This seems fine from an MCO POV, but based my basic understanding of the Hypershift featuregate system, wouldn't we need a companion PR to make https://github.com/openshift/hypershift/blob/main/api/hypershift/v1beta1/featuregates/featureGate-Hypershift-Default.yaml#L43 enabled? This PR would effectively make the hypershift-deployed bootstrap MCO/MCC/MCS pod enable OSStreams, but without the hypershift side enablement, we would still be booting RHEL9?

(Also to check, the Hypershift feature is also gated behind this same-name-different-implementation FG right?)

…Hypershift With the MCO ExternalTopologyMode guard removed (openshift/machine-config-operator#6308), HyperShift clusters can now process OSImageStream during bootstrap. This graduates the OSStreams feature gate from TechPreviewNoUpgrade to Default for the Hypershift cluster profile, enabling RHEL 9/10 dual-stream support for hosted control planes by default.

Align the feature matrix with the Hypershift-only promotion.

Line 116 marks OSStreams as Enabled in all eight columns, including every SelfManagedHA profile. The PR objective promotes OSStreams to Default for Hypershift. Regenerate this row from features/features.go so only feature sets that actually enable OSStreams are marked Enabled; otherwise, features.md advertises unsupported SelfManagedHA combinations.

Hey @JoelSpeed

The verify-feature-promotion check fails because Sippy finds 0 tests matching the FeatureGate:OSStreams] pattern. The root cause is that our e2e tests in HyperShift used [Feature:NodePoolOSImageStream] in the Ginkgo Describe blocks instead of [FeatureGate:OSStreams].

The featuregate-test-analyzer builds its search pattern as:

testPattern := fmt.Sprintf("FeatureGate:%s]", featureGate)

So without [FeatureGate:OSStreams] in the test names, Sippy can't index them for the promotion gate.

Fix PR: openshift/hypershift#9297 — adds [FeatureGate:OSStreams] to both OSImageStream e2e Describe blocks.

Once that PR merges and the CI job (e2e-v2-aws-techpreview-osimagestream) runs enough times, Sippy will have the required test data (≥5 tests, ≥14 runs, ≥95% pass rate) and verify-feature-promotion should pass here.

if it's the same test just name changed to have the gate find the data, I'd argue it should be fine to merge as it already has the required runs

jparrill · 2026-08-13T09:00:20Z

Totally agree @celebdor, who can override the test in order to continue with merge?

openshift-ci · 2026-08-13T09:28:12Z

@jparrill: The following test failed, say /retest to rerun all failed tests or /retest-required to rerun all mandatory failed tests:

Test name	Commit	Details	Required	Rerun command
ci/prow/verify-feature-promotion	`89478e4`	link	true	`/test verify-feature-promotion`

I agree, where's the sippy link for the tests?

JoelSpeed · 2026-08-13T10:33:25Z

Right so i can see the tests here, and the data looks good

There are only 3 tests, @yuqi-zhang do you know if the OCP version had more tests?

@jparrill Are we confident that these three tests are sufficient coverage for the entire feature here? We would normally be asking for at least 5 individual tests, but if this is genuinely covering the whole feature we can make and exception

yuqi-zhang · 2026-08-13T14:01:34Z

There are only 3 tests, @yuqi-zhang do you know if the OCP version had more tests?

When we GA'ed, we did have an override to get this in ASAP #2849 but I think we did have 5 tests at the time. Currently there's 11 tests attached to the gate according to https://sippy.dptools.openshift.org/sippy-ng/feature_gates/5.0/OSStreams

Also want to bump #2950 (review) if someone can check my understanding.

jparrill · 2026-08-14T08:11:22Z

Hey @JoelSpeed IMHO for graduation, Yes, this should come in before GA and we are covered api wise:

We are adding more and more coverage for real node testing, starting with this OCPBUGS-105802: Use the correct v1 mcfg api for OSImageStream during ignition hypershift#9283 from @bennerv
We will add more coverage to cover RHEL-9/10 streams and upgrade path with real nodes (but we need to be smart in where we locate those tests + the pace we execute them)
