Why the changes were made

Two ginkgo.PIt e2e specs in tests/e2e/virt_backup_restore_suite_test.go were scaffolded pending upstream fixes:

Both landed upstream via migtools/kubevirt-datamover-controller#124 (fixes #169) and #186 (#73 phase 4: per-disk DataDownload isolation and scratch-PVC sizing hardened, with TestDataDownloadReconcile_ConcurrentMultiDisk/TestCalculateScratchPVCSize as proof). This flips both specs from PIt to It and updates the stale "blocked on X" comments/titles accordingly.

A third PIt in the same file (CNV-85377, an external KubeVirt/CNV bug) is unrelated and stays pending.

This PR went through several rounds of live e2e validation against real GCP/Azure clusters, which surfaced and fixed three real bugs beyond the initial flip:

1. Wrong correlation field simulated in the decoy (fixed in 5416be4e). The restore-run-state-flip test originally simulated a foreign restore attempt using a mismatched velero.io/restore-uid label. This doesn't match what #124 actually shipped: allSiblingDataDownloadsCompleted correlates siblings by velero.io/restore-name, not restore-uid (an earlier draft of the fix used restore-uid; #124's restore-name-based version is what shipped). The decoy now uses a genuinely different restore-name.

2. Status update on a CRD with no status subresource (fixed in 5416be4e). The decoy's status was set via Status().Update(), which unconditionally 404s because the DataDownload CRD (v2alpha1) has no status subresource registered at all (kubevirt_datadownload_controller.go itself only ever uses plain r.Update() for this same reason, per its own code comment). Switched to plain Update(), wrapped in retry.RetryOnConflict since kdm-controller concurrently reconciles the decoy the moment it's created, racing a bare Update() against its bumped resourceVersion. Confirmed passing live on a GCP cluster after this fix (1 Passed | 0 Failed).

3. Race between DataUpload existence and its expected-backup-type annotation (fixed in 82477ab2). lib.GetDataUploadForBackup returns the DataUpload's kubevirt-datamover.io/expected-backup-type annotation but didn't error if it's empty — kubevirt_dataupload_controller.go stamps that annotation on its own reconcile, racing the poll for the object. Hit live on kubevirt-datamover-controller#199's CI (virt-kdm-e2e-test-aws), reported here. runKubevirtDMBackup's Eventually now treats an empty annotation as not-ready-yet instead of succeeding on object presence alone.

Also documented (not yet auto-detected, see caveat below): a live run also hit https://redhat.atlassian.net/browse/CNV-89684 once — virt-controller's VirtualMachineBackup status condition froze on "... is being attached to VMI ..." for the full 20-minute timeout even though the underlying attach had already succeeded within a second. RBAC-confirmed this is a KubeVirt/CNV core issue (kdm-controller only ever has get on virtualmachinebackups/status), not something in this repo's control — same pattern family as the already-tracked CNV-85377. Registered in lib.CheckIfFlakeOccurred for documentation, but this suite doesn't yet feed accumulatedTestLogs the way backup_restore_suite_test.go does, so it's not yet auto-detected in CI output — wiring that up is a separate, larger change.

Summary by CodeRabbit

  • Tests
    • Expanded end-to-end coverage for restoring data downloads when stale sibling resources are present.
    • Added change-block tracking restore coverage for multi-volume isolation and concurrent processing.
    • Improved validation of restore-attempt correlation, multi-disk handling, and failure scenarios.
    • Improved test reliability by waiting for backup metadata to become available before continuing.
    • Documented an intermittent attachment issue to support clearer test-result interpretation.

migtools/kubevirt-datamover-controller#124 fixed openshift#169 (stale-sibling
DataDownload correlation now keys off velero.io/restore-name, not just
VM identity) and openshift#186 (issue #73 Phase 4) hardened per-disk DataDownload
isolation for multi-disk restores -- both scaffolded PIt placeholders can
now run as real specs. A third PIt in the same file (CNV-85377, an

Walkthrough

The pull request activates CBT restore coverage, improves DataUpload readiness checks, correlates restore attempts by restore name, adds conflict-retried decoy updates, and registers a known virt-controller flake pattern.

Changes

CBT restore test coverage

Layer / File(s) Summary
Backup readiness and flake metadata
tests/e2e/virt_backup_restore_suite_test.go, tests/e2e/lib/flakes.go
The backup helper waits for the expected backup type annotation. The suite documents known flakes and adds attachment-flake detection metadata.
Stale-sibling restore isolation
tests/e2e/virt_backup_restore_suite_test.go
The stale-sibling test correlates attempts by restore name. It marks decoy DataDownload objects Failed with conflict-retried updates and verifies the VM transition.
Active CBT restore scenarios
tests/e2e/virt_backup_restore_suite_test.go
CirrOS and multi-PVC CBT restore tests are active. Assertions cover per-disk isolation during concurrent reconciliation.

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

Merge Risk: 🔵 Low · up to 82477

The PR enables two restore end-to-end scenarios and improves handling of asynchronous restore metadata. It is mergeable with owner awareness that failed runs can leave resources behind and affect later test executions; this is a bounded test-isolation risk rather than a production-path regression.

Register cleanup for the multi-PVC resources.

The newly active test creates fixed-name Backup and Restore resources but has no local cleanup defer. If an assertion fails before Lines 977-980, the multi-PVC namespace remains. The shared AfterEach tracks the outer restoreCase instead of this multi-PVC case, so it does not provide reliable cleanup here. Add cleanup before runKubevirtDMBackup, and delete the Restore before the Backup to support focused reruns.

Verify both disk-specific DataDownloads explicitly.

/test 5.0-e2e-test-kubevirt-aws

Failure was a backup timeout (VM-disk hotplug-attach stall, contended by repeated EvictionStrategy... not migratable events on the VMI — 1222x during the run) — unrelated to this PR's PIt→It flip, matches the caveat already noted above. Retesting to confirm it's transient CI-cluster node churn rather than a recurring issue.

…oy test

Live e2e validation of the restore-run-state-flip test (unpended in the
prior commit) surfaced two real bugs in the test itself, not in the
underlying openshift#169 fix:

1. The decoy DataDownload used a mismatched velero.io/restore-uid label
   but the SAME velero.io/restore-name as the real restore. The actual
   shipped openshift#169 fix (migtools/kubevirt-datamover-controller#124,
   allSiblingDataDownloadsCompleted) correlates siblings by restore-name,
   not restore-uid -- an earlier draft used restore-uid, but #124's
   restore-name-based version is what shipped. The decoy now uses a
   genuinely different restore-name to correctly simulate a stale sibling
   from a different restore attempt.

2. The decoy's status was marked Failed via Status().Update(), which
   unconditionally 404s: the DataDownload CRD (v2alpha1) has no status
   subresource registered at all (confirmed via
   `oc get crd datadownloads.velero.io -o jsonpath=...subresources`).
   kubevirt_datadownload_controller.go itself only ever uses plain
   r.Update() for this same reason. Switched to plain Update(), wrapped in
   retry.RetryOnConflict since kdm-controller concurrently reconciles the
   decoy (New -> Accepted) the moment it's created, racing a bare Update
   against its bumped resourceVersion.

Cross-validated live against a GCP cluster with peer sessions working the
kubevirt-datamover-controller and kubevirt-datamover-plugin repos; the
controller-side peer confirmed both findings against their own source and
an existing code comment documenting the missing status subresource.

Update for reviewers: this PR was updated after the initial approval with a real fix, not just a rebase. Live e2e validation against a GCP cluster caught two bugs in the restore-run-state-flip test itself (both now fixed in the latest commit, described in the updated PR body above):

  1. The decoy DataDownload's foreign-attempt simulation used the wrong correlation field (restore-uid instead of the restore-name label the shipped Add different cloud provider support between BSL and VSL #124 fix actually keys off).
  2. The test was calling Status().Update() on a CRD with no status subresource registered, which unconditionally 404s regardless of the object's real state.

Worth another look given the substance of the change.

Create the decoy before the real Restore.

CreateRestoreFromBackup starts reconciliation before this decoy exists. While this setup lists the BSL, creates the decoy, and retries its update, the real DataDownload can complete and the controller can evaluate sibling completion first.

The VM-resume assertion can then pass without testing restore-name isolation. Create and mark the decoy Failed before creating restoreName.

If RetryOnConflict returns an error, Line 923 aborts the spec before Line 924 registers cleanup. The directly created, fixed-name dd-stale-sibling-decoy can remain and make a later run fail at Create.

The live e2e validation run that confirmed this PR's decoy fix also hit
CNV-89684 once: virt-controller's VirtualMachineBackup status condition
stayed frozen on "... is being attached to VMI ..." for the full 20-minute
backup timeout, even though the underlying volume attach had already
succeeded within a second. Confirmed via RBAC that kubevirt-datamover-controller
only ever reads virtualmachinebackups/status (get-only) -- this is a
KubeVirt/CNV core issue, not something in this repo's control.

Registers the pattern in lib.CheckIfFlakeOccurred alongside the existing
CNV-85377 entry (a related frozen-condition pattern with a different
trigger), and documents it on runKubevirtDMBackup with an honest caveat:
this suite doesn't yet feed accumulatedTestLogs (unlike
backup_restore_suite_test.go), so the registry entry is documented but not
yet auto-detected in CI output for virt/kdm specs -- wiring that up is a
separate, larger change.

Related flake worth fixing while in this file: lib.GetDataUploadForBackup (tests/e2e/lib/backup.go:149) only waits for the DataUpload object to exist, not for kubevirt-datamover.io/expected-backup-type to actually be stamped — a race against kubevirt_dataupload_controller.go's reconcile. Hit this today on kubevirt-datamover-controller#199's CI (virt-kdm-e2e-test-aws), unrelated to that PR's diff. Suggest making the Eventually also wait for the annotation to be non-empty, not just object presence.

lib.GetDataUploadForBackup returns the DataUpload's
kubevirt-datamover.io/expected-backup-type annotation but doesn't error if
it's empty -- kubevirt_dataupload_controller.go stamps that annotation on
its own reconcile, racing runKubevirtDMBackup's poll for the object. An
empty value at that point means the DataUpload was observed before the
controller's reconcile landed, not that the backup type is genuinely
empty. The Eventually wrapper now treats an empty annotation as
not-ready-yet and keeps retrying, instead of treating object presence
alone as success.

Per openshift#2404 (comment)
-- hit live on kubevirt-datamover-controller#199's CI
(virt-kdm-e2e-test-aws), unrelated to that PR's own diff.

Fixed in 82477ab2 (re: #2404 (comment)): runKubevirtDMBackup's Eventually now treats an empty expected-backup-type annotation as not-ready-yet (returns an error to keep retrying) instead of succeeding as soon as the DataUpload object exists.

984-989: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Add diagnostic messages to the activated multi-PVC assertions.

The activated spec has setup and restore assertions without messages at Lines 996-1001, 1009-1011, 1024-1027, and 1031-1033. Add messages with the namespace, VM, backup, and restore names so failures identify the failed operation.

As per coding guidelines, “Ginkgo test assertions should include meaningful failure messages to help diagnose what went wrong.”
