From 6791056cd1257ed027dd9ebfa7d22504ef865c80 Mon Sep 17 00:00:00 2001 From: Tiger Kaovilai Date: Tue, 4 Aug 2026 17:16:43 -0400 Subject: [PATCH 01/33] Add multi-PVC VM e2e scaffolding for kubevirt-datamover Adds a CirrOS VM template with two disks (existing rootdisk DataSource plus a blank data disk) and a corresponding backup/restore table entry using CSIDataMover, verifying both PVCs come back Bound after restore. Covers the "Multi-PVC VM" gap tracked in migtools/kubevirt-datamover-controller#99. Not yet run against a real cluster.

18:30:54 -0400 Subject: [PATCH 03/33] Fix CodeRabbit findings on incremental-sequence e2e coverage - Register velero v2alpha1 in the e2e suite scheme (GetDataUploadForBackup lists DataUploadList, which was otherwise unregistered -> runtime error). - Fix a real bug: the outer AfterEach undeploys CSI+datamover and deletes cirros-test after every spec it fires for, including this Describe's specs -- which would tear the VM down between the incremental-sequence scenarios. Collapse them into a single ordered It (with ginkgo.By steps) that does its own full teardown at the end, and register the case via updateLastBRcase/prepareBackupAndRestore so the shared AfterEach's now- redundant cleanup is a harmless no-op instead of acting on stale state. - Use a bounded context for the PVC Get in vmPvcsBound, instead of context.Background(). - Add failure messages naming the namespace/VM/backup to gomega assertions across the new setup/teardown/backup-sequence code. Not fixed: the personal-registry kubevirt-datamover-plugin image override is flagged as a pre-merge security concern, but it's an explicit, already- documented temporary pin (see prior commit) needed to exercise an unmerged upstream PR -- removing it would defeat this PR's own purpose until migtools/kubevirt-datamover-plugin#41 merges.

Per docs/design/kubevirt-datamover.md and the plugin's own README, restore just needs a normal Velero Restore -- the VirtualMachine RestoreItemAction plugin creates the DataDownload CR automatically from backup-recorded annotations, and separately discards the restored VMB/VMBT so restore doesn't re-trigger a backup. No manual CR driving needed, mirroring how backup already works. Verifies success via the existing generic lib.CreateRestoreFromBackup/IsRestoreDone/IsRestoreCompletedSuccessfully helpers plus a new lib.GetDataDownloadForRestore (mirrors GetDataUploadForBackup) confirming the DataDownload itself reached status.phase=Completed -- proving the datamover path actually engaged, not just that the restore completed some other way. Extracted runKubevirtDMBackup (shared create+wait+verify-backup helper) out of runSequenceBackup to avoid duplicating that logic a second time for the restore test. Also scaffolds two ginkgo.PIt (real, compiling, not run) for gaps explicitly still open per kubevirt-datamover-controller#73's phased plan: multi-disk restore (phase 4, not yet hardened -- new cirros-test-multipvc-cbt.yaml template ready for when it lands) and restore from an incremental (not full) backup (phase 5, not yet e2e-validated upstream even though the chain-rebase logic may already support it internally).

Date: Tue, 4 Aug 2026 23:22:03 -0400 Subject: [PATCH 08/33] Fix CodeRabbit findings: rollout check, checkpointName, image-override gate - IsDeploymentRolledOut: also require Status.Replicas == wantReplicas alongside UpdatedReplicas/AvailableReplicas -- without it, a rollout scaling down old replicas could report done while stale pods still lingered. - GetVMBBackupType: check the found bool for status.checkpointName too (same fix already applied to status.type), so an unpopulated field returns a clear error instead of silently returning "". - Gate both kubevirt-datamover pre-merge image overrides behind an explicit OADP_E2E_KDM_PREMERGE_IMAGES=true env var instead of always-on, so this suite defaults to the operator's normal images for anyone else running it and only pulls the mutable personal-registry builds when deliberately testing those two PRs.

Without this, the controller would hit RBAC-denied errors reconciling any DataDownload, regardless of image correctness, once a real velero restore actually tried to drive it (which migtools/kubevirt-datamover-plugin#41 now makes possible). Synced config/kubevirt-datamover-controller_rbac/role.yaml and the matching block in bundle/manifests/oadp-operator.clusterserviceversion.yaml (serviceAccountName: oadp-kubevirt-datamover-controller-manager) to byte-match config/rbac/role.yaml from migtools/kubevirt-datamover-controller PR #124 (issue #73 phase 3, commit 825d176), which added these rules on the source side but were never pulled into OADP's bundled copy -- normally done via `make update-kubevirt-datamover-manifests KUBEVIRT_DATAMOVER_PATH=...`, done here by hand since no local checkout of that repo is available in this environment. This is a real, pre-existing gap (not introduced by this branch's other changes) that this branch's e2e work would otherwise have hit blind, so fixing it here rather than filing it separately.

IsNamespaceDeletedClearingStuckVMBFinalizers works around it by clearing stale finalizers on every poll; safe to remove once that kubevirt issue is fixed. Also fixes a real race: VirtualMachineBackup is ephemeral and can be deleted by virt-controller before the overall backup finishes uploading, so checking its status after backup completion (as before) could find nothing. runKubevirtDMBackup now takes an onDataUploadFound callback invoked as soon as the DataUpload appears, letting the incremental- sequence spec check VMB status while it still exists. migtools/kubevirt-datamover-plugin#41 merged; the e2e image override now points at #44 instead, which fixes a still-open bug where restored PVCs come back with stale spec.volumeName/status, causing the datamover controller to reject them as "already bound".

Adds a second restore phase to the existing CBT-restore It, reusing the same backup: forces a PVC binding conflict on the freshly-restored PVC (setting spec.volumeName is enough -- kdm-controller's Accepted check only inspects the PVC's own fields, not whether the referenced PV exists), which triggers the controller's real rejection path deterministically rather than racing its reconcile loop or patching DataDownload status by hand. Asserts the restore ends PartiallyFailed, the DataDownload is Failed, and the VM never reaches Running. This has to live inside the same It as the happy-path restore rather than a separate one: the suite's shared per-test AfterEach tears down the DPA (and velero/BSL with it) after every It, and a freshly recreated DPA gets a new random BSL S3 prefix each time, so a second It could never have restored from this same backup.

Re-ran the full scenario (happy path, Block volumeMode, spec.selector, and the forced-PVC-conflict failure mode) against both tips together: still passes end-to-end.

Also asserts Block volumeMode is actually exercised, that source PVCs carry no spec.selector (a precondition kubevirt-datamover-plugin's restore path assumes), and adds a rejected-restore negative scenario (forced PVC binding conflict -> DataDownload fails -> VM stays halted). Adds a HasQemuGuestAgent helper and a VmBackupRestoreCase.HasGuestAgent field, cross-checked live against the VMI so the checksum strategy can't silently drift from what the fixture actually provides. Adds a third ginkgo.PIt for kubevirt-datamover-controller#169 (stale-sibling DataDownload blocking the VM run-state flip across separate restore attempts), gated on the same Phase 4 branch as the two existing multi-disk/incremental placeholders -- the fix already exists there, so this asserts the fixed behavior once Phase 4 lands rather than locking in the current bug. Makes the kubevirt-datamover-plugin/controller pre-merge image overrides unconditional rather than gated behind OADP_E2E_KDM_PREMERGE_IMAGES=true -- the env-var gate's silent fallback to the default (unrelated) images was the root cause of several hours of phantom debugging this session. New lib helpers: DeleteVeleroBackupAndRestore (velero-CLI-based backup/restore cleanup, safe to call before DPA teardown), ExecuteShellCommandInPod (extracted from ExecuteCommandInPodsSh for real shell scripts with pipes).
