collectUnderlyingResources returned nothing for a non-VMInstance kind, so prepareForRestore did nothing for a standalone VMDisk: no HelmRelease suspend and no DataVolume delete. An in-place VMDisk restore then raced Flux/CDI — the restored HelmRelease reinstalled and CDI recreated the DataVolume over the same PVC name the data mover was repopulating, wedging the RestoreJob. Report a standalone VMDisk's own disk as its underlying resource, so the existing (VMInstance-proven) restore preparation suspends the vm-disk-<name> HelmRelease, deletes its DataVolume and — with keepOriginalPVC — renames the live PVC before the data mover recreates and repopulates it. No VM, so no IP/MAC is collected. A VMInstance is halted before its disks are touched; a VMDisk target is not, and every VMInstance disk is a VMDisk. Renaming the PVC of a disk a running VM mounts leaves the original Terminating behind pvc-protection, Velero skips a PVC that still exists, and the RestoreJob would report Succeeded having moved nothing while the VM loses its disk on the next restart. An in-place VMDisk restore now fails before changing anything when a Pod that has not terminated mounts the disk's PVC, naming the Pod and telling the user to stop the VM or restore the VMInstance instead. A VMDisk Backup taken before the disk was recorded as its underlying resource has none, so its disk is now derived from the application name and such a restore is prepared and checked for a mounting Pod as well. The per-disk orLabelSelectors stay a VMInstance concern. A VMDisk strategy already selects its disk, and Velero rejects a Backup or Restore that carries both labelSelector and orLabelSelectors, so appending them for a VMDisk would break a strategy written with labelSelector. When an in-place restore fails after preparation, nothing is rolled back: resuming the disk's HelmRelease while its PVC is renamed and its DataVolume deleted would have CDI import a fresh disk under the original name, which looks healthy and hides that the data sits in the -orig- PVC. The failure message and a Warning event now name the suspended HelmReleases and the -orig- PVCs so the user can recover them, read back from the cluster, so a failure before a step ran does not name what it would have left. Preparation takes the target apart before Velero validates the Restore, so it is refused up front when the Velero Backup is gone or not Completed. That check now runs on every pass behind the same failure path as the rest of preparation, and a FailedValidation Restore fails the RestoreJob like a Failed one instead of leaving it Running. A HelmRelease suspend or a VM halt that did not happen now stops preparation instead of renaming and deleting under a running release or VM, and a VMInstance's disks are renamed only once its launcher Pod has let go of them. A VMDisk held only by a Pod already being deleted is waited for rather than refused, for up to 30 minutes after the RestoreJob started. Between renaming a kept disk's PVC and deleting its DataVolume, CDI can recreate an empty PVC under the original name. Velero then skips the PVC as already present, the RestoreJob reports Succeeded and the VM boots a blank disk. Once the DataVolume is gone, preparation now deletes a PVC found under the original name, read uncached, before the Velero Restore is created. Preparation spans several reconciles, so the RestoreJob records a PreparationStarted condition before it first changes the target, and retries without changing anything when recording it fails. A refusal on a later pass (the Velero Backup expired, a VM started on the disk) then names what preparation left behind instead of claiming that nothing changed, and a preparation still waiting 30 minutes after it started fails the same way instead of polling forever. Now that a VMDisk target is prepared, keepOriginalPVC=false reaches it too: its DataVolume is deleted with orphan propagation and the bound PVC is deleted before the Restore, as for a VMInstance disk. Left in place, Velero would skip it and CDI would refuse the DataVolume the resumed HelmRelease creates. Assisted-by: LLM Signed-off-by: Andrey Kolkov <androndo@gmail.com>
