feat(migration): tenant self-service VM import from VMware vSphere - #3931

I read this branch against the Konveyor Forklift v2.11.5 sources it pins, since the riskiest assumptions here are about Forklift's behavior rather than this repo's, and the PR body itself names them as untested. First the good news, because it is substantial.

The tenant API resolves what #1982 was rejected for: no image field, no Secret reference, no namespace field, no raw Kubernetes primitive anywhere a tenant can reach, zero tenant RBAC on forklift.konveyor.io, and outputs that genuinely outlive the task — I traced the ownerRef graph end to end and the scaffolding/outputs split holds. All eight empirically-found fixes named in the PR body are really in the code and match upstream: the cacert requirement is exactly Forklift's pkg/controller/provider/validation.go:295-304; the plan label really carries the Plan UID (pkg/controller/plan/kubevirt.go:110); Forklift really does patch the populated PVC with an ownerRef to the VM it builds (kubevirt.go:558-563), and the handoff's ordering against that — clear ownerRefs unconditionally, delete the owning DataVolume, pin Retain, copy volumeMode/accessModes, rewrite claimRef with UID — is correct; api.PhaseCompleted is the terminal phase and error.reasons is checked first, so "Completed with error" reads as failure; the controller starts with no Forklift watch and uncached unstructured reads; NoMatch becomes a condition rather than an error; the Deployment is restricted-clean; progress survives a renamed pipeline step. Credential rotation also works: Forklift's Provider controller watches Secrets through its reference tracker, so an edited Source password gets retested. The vm-disk- release-prefix contract the handoff leans on is real (vm-disk-rd), and the opt-in bundle wiring with the components pass-through is clean and tested.

Design-level requests, including a rename of the API group, are on cozystack/community#62. What follows is what blocks in this implementation; requesting changes on the first four.

1. The mapping-learning loop cannot converge — the IDs it needs are not on the Plan.

unmappedRefs parses the VMNetworksNotMapped/VMStorageNotMapped condition items for network and datastore IDs, but Forklift puts the VM references there: pkg/controller/plan/validation.go:940,960 appends ref.String() of the VM, rendered id:vm-1234 name:'web-01' (pkg/apis/forklift/v1beta1/ref/ref.go:29). The last-token parse yields name:'web-01, which learnMappings writes as a map source ID; the map controller marks it SourceNetworkNotValid (not found in inventory), and on the next pass hasSourceID finds the garbage entry already present, learns nothing, and the task sits in Validating forever. Map resolution is an exact-ID lookup with no wildcard to fall back on (pkg/controller/plan/adapter/vsphere/validator.go:80,116), and the network/datastore IDs of a VM appear on no Forklift custom resource at all. TestUnmappedRefsReadsForkliftValidation feeds bare IDs like "network-31" — a shape Forklift never emits — so the suite locks in the wrong contract. The fix is the one the design doc already implies: an authenticated GET against the forklift-inventory service for each named VM (its networks and disks[].datastore refs), writing both maps from that. Still Forklift's view of vSphere, so the no-second-client boundary survives; the no-inventory-client implementation detail does not.

2. Set targetPowerState: "off" on every Plan, or Forklift boots the migrated guest before the handoff.

With no targetPowerState, v2.11.5's determineRunStrategy (pkg/controller/plan/kubevirt.go:3649) matches the source's pre-migration power state: a cold migration powers off the source, records RestorePowerState: On, and creates the target VM with RunStrategy: Always — it boots the moment the transfer completes. The handoff then deletes the populated PVC out from under a running virt-launcher and rewrites the PV's claimRef mid-flight, and the guest is a duplicate of a production machine on the network — the exact hazard the runStrategy: Halted comment in createVMInstance prevents one layer up. Every VM in a production migration is running when migrated, so this fires on the primary use case. One line in createPlan (pkg/apis/forklift/v1beta1/plan/vm.go:27 for the constant).

3. Outputs need an identity marker: a re-imported name silently attaches stale disks and lets the fresh transfer be destroyed.

findOutputCollision checks only VMInstance names, and the handoff's idempotency checks (adoptVolume, ensureVMDisk) treat any pre-existing PVC or VMDisk of the expected name as their own prior output, with no identity check. Concrete failure: a first import half-succeeds, the tenant deletes the VMInstance but keeps the disks, and retries under the same name — the collision check passes, adoptVolume early-returns on the leftover vm-disk-<name>-disk-0, the freshly transferred claim keeps its ownerRef to the Forklift VM, fulfill deletes that VM, garbage collection destroys the new transfer (the 357 ms hazard through a side door), and the "succeeded" import points at stale data. The same gap fires the other way: a crash or status-write conflict between creating outputs and recording them makes the next pass read the controller's own VMInstance as a tenant collision and terminally fail an import that succeeded. And findOutputCollision routes through terminalFail, which fails the whole task and abandons sibling transfers mid-flight, where the design promises per-VM failure. One mechanism fixes all three: label created VMDisks, VMInstances and handoff PVCs with the Task UID and source VM ID, treat marker-match as resume, marker-absence as a per-VM collision failure. A label creates no GC linkage, so the outputs-outlive-the-task property is untouched.

4. EFI guests currently import as BIOS, silently.

The design names #3002 (vm-instance firmware) as a merge-order dependency, but #3002 is still open and this controller neither writes nor inspects firmware. A UEFI guest imports "successfully" and does not boot. Minimum interim fix that keeps this PR mergeable ahead of #3002: read the bootloader from the Forklift-built VirtualMachine that fulfill already parses, and fail that VM per-VM with a message naming EFI as unsupported-until-#3002, instead of producing an unbootable instance.

Smaller items, take or leave:

• deployment.yaml tests .Values.migrationController.metrics.enable; values ship metrics.enabled — metrics are silently never enabled while the port is still declared.
• The forklift package has no pre-delete hook for the ForkliftController operand; the design doc records the uninstall deadlock on the operand's finalizer as observed live.
• The migration-controller/values.yaml comment still points operators at migration.vddkImage and a vddk-image ConfigMap key; the shipped key is vmImport.vddkImage.
• ensureMaps does not tolerate NoMatch the way reconcileVM does; reachable in the window between Forklift's CRDs vanishing and the Source's 10-minute recheck, where it hot-loops with no status written.
• Name-length edges: a Task name over 63 characters breaks scaffolding creation via the owned-by label value with only a requeue loop to show for it, and a 48-character vms[].name with ten or more disks overflows the DataVolume's app.kubernetes.io/instance label. Both are one CEL cap away.
• The WaitForFirstConsumer failure message tells the tenant to set spec.storageClass, but the field is immutable and the task terminal by then — it should say to recreate the task.
• ReasonVMNotFound is declared and never set.

On the merge path. Items 2 and 4 are hours; 3 is a day; 1 is the real work and retires the "no inventory client" line in the package docs. Given that three independently wrong behaviors sat past the vCenter-auth boundary the PR body flags as untested, I would gate merge on one full real-vCenter import — the lab run the design's own test plan names — with the screenshots and the website follow-up alongside. Nothing here says start over: the API, RBAC, packaging and the handoff's ordering are right, and the eight hard-won fixes all held up under source verification. The last mile just runs through a real vCenter.

I re-read the branch at 6824eba against the Forklift v2.11.5 sources. All four blocking items from the previous review are fixed, and I verified each in the code rather than in the reply: the condition parser is gone with its test, and populateMaps feeds from an inventory client that verifies TLS against the serving-cert CA and re-reads the projected token per call; every rendered Plan pins targetPowerState: off per VM, which determineRunStrategy honours ahead of its match-the-source default; the Task-UID + VM-ID markers are on every created PVC, VMDisk and VMInstance, every idempotency early-return checks them, and collision is per-VM and checked before a transfer is spent; and firmware is written through with Secure Boot rather than refused, with the branch stacked on #3002. The merge gate ran — a full import from a live vCenter — and what it forced out (the SATA bus default, the transfer-volume finalizer, spec.hosts, the cores/sockets split) is the strongest material in the PR. The new surfaces all read sound: the finalizer matches only the engine's volumes by plan-UID label and fails open with the leftover named, the picker publishes through a Source-owned ConfigMap so no second component ever holds a credential, and the hosts overrides follow the established projection pattern.

One functional defect remains, plus three small ones and the mechanical CI items.

1. One missing VM fails all of its siblings, and the design promises the opposite.

populateMaps is called from reconcileVM — per VM — but sourceTopology iterates task.Spec.VMs and queries the inventory for every VM of the task on each call. Two consequences. A notFoundError for any VM propagates into whichever VM's reconcile happened to trigger it, so one wrong managed-object reference — the likeliest tenant typo on this API — marks every VM in the task Failed with a message naming a different machine, where the design doc's failure table says a missing VM fails per-VM while its siblings proceed. And the cost is quadratic: a task of N VMs issues N×N inventory GETs per pass, repeated every TransferRequeue while anything is transferring — for a 65-machine batch that is ~4,200 HTTP calls every 20 seconds against forklift-inventory. Both go away with the same small change: pass the current request into populateMaps and have sourceTopology fetch only that VM's record, adding its networks and datastores to the maps. Per-VM containment falls out, and the per-pass cost drops to one GET per VM.

2. The shared inventory client's lazy TLS setup is a data race.

main.go builds one inventoryClient for both reconcilers ("One client for both reconcilers"), and client() does an unsynchronized check-then-assign on c.http. The source and task reconcilers run on separate goroutines, so two first calls can race the build; in practice the loser's client leaks, under -race it fails. A sync.Once around the construction closes it.

3. A crash at the wrong moment still mislabels a finished import, and the markers you added can fix it.

fulfill's recovery branch for a VM that is already cleaned up trusts only task.Status.VMs: if the controller dies between deleting the scaffolding VirtualMachine and the status write that records the outputs, the next pass finds no VM and no recorded names and fails that VM with "the transfer completed but no imported VM was found" — a per-VM Failed on an import whose disks and instance exist and are healthy. The outputs now carry OutputTaskUIDLabel + OutputVMIDLabel, so instead of failing, that branch can list VMInstances by marker and reclaim the names. No data is at risk either way; this is the difference between a crash being invisible and a tenant reading Failed on a machine that works.

4. Three comments still describe the mechanism this round deleted.

ensureMaps's doc comment ends "learnMappings then fills them in. That loop is why this controller needs no inventory client"; populateMaps's own doc comment opens with two paragraphs about reading the Plan's NotMapped conditions; and reconcileVM still says surfacing Forklift's verdicts "beats re-implementing its checks against an inventory we would have to query ourselves." All three assert the opposite of the code beneath them, and the first two describe an approach the PR's own commit history proves cannot work. Worth sweeping in the same pass as item 1, since that is the code they sit on.

CI is red on four checks, all mechanical as far as the logs show: Verify generated code and pre-commit's run-make-generate hook want a codegen run, and two helm-unittest cases fail — cozystack-api ClusterRole grants Option provider sources (tests/rbac_test.yaml) and forklift-operator image pinning (tests/images_test.yaml). E2E skipped downstream of those. Separately, the cozystack/website checkbox is still unticked with no follow-up opened, and the PR is still draft.

With item 1 fixed, the comments swept, CI green and the website follow-up linked, I will approve — that also clears the API-owner gate, since the sizeable-API-change check is waiting on exactly this review chain. Items 2 and 3 I would take in this PR for the price of their size, but neither would keep me from merging.

Approved. I read the round at d217f59 in the diffs rather than the summary: sourceTopology is scoped to the VM being reconciled with a test pinning the call count — the part that would regress silently; the inventory client's lazy setup is guarded with a mutex, and the reasoning for a mutex over sync.Once is better than the suggestion it answers, since Once would have latched a transient serving-cert failure for the life of the process; the crash-recovery branch reclaims unrecorded outputs by their markers with the not-someone-else's-output case tested; and all four stale comments are gone, one more than the review asked about. The two helm-unittest failures both turning out to be real defects rather than stale assertions — and the forklift digests rotting again on a ten-day cycle — is the strongest evidence yet for mirroring those images, which I read as this PR's first follow-up rather than its problem.

This approval also clears the API-owner gate for the forklift.cozystack.io group: the API shape, its RBAC, and the rename have all been through review and I am satisfied with where they landed.

Two things at merge time, neither a change to this branch. The e2e failure is not this PR — the Talos sandbox never bootstrapped, no suite ran, and nothing in this change was reached — but it should be re-run and green before merging rather than waved through on that explanation. And the branch stacks on #3002, so that lands first.
