Good job! First quick review with some comments. Also wondering if we should skip fs overhead inflation in renderPvcSpecVolumeSize
when using a populator.

Do we want to continue with the regular flow (including getPodFromPvc
) if the PVC is using a populator?

if the pvc is using populator it should have this annotation, I guess we can add the check for the populators for the time in between the creation of the pvc' and the update of the progress on it

Maybe change this function name to something like shouldUseCDIPopulator
, shouldUsePopulator
, or checkPopulatorRequirements
? I think usePopulatorsForPopulation can sound odd.

this seems complicated to me. If the CR is owned by the dv, then only explicitly delete when the target PVC is bound? Seems simpler to me

it is redundant to do the delete if we don't use populators, and phase succeded is basically the same as target PVC is bound, so you say to remove the deletionTimestamp check when I add the ownerRef, then sure I guess we can

I don't love that this function has the side effect of mutating the datavolume, perhaps it would be better to explicitly set this somehow in one place? Currently, this function is called in multiple places

Totally forgot that the controller should be watching everything it creates, so should be watching VolumeImportSources
owned by datavolumes.
Also, I think it would be better to see if the resource exists before creating, saves a trip to the apiserver, still have to handle already exists because cache is not perfect

Would it be best to simply have a whitelist of allowed annotations? What's your opinion?

it seems there are too much allowed annotations comparing to annotations that shouldn't be added.. and that's how I missed a bunch, I think its easier to know which we don't want to add

Too much? Could probably count all the annotations we care about on two hands? Maybe three? They're all defined and unlikely to change. Would be nice to have one place (or maybe one place for each source) that states "these are the annotations we care about for datavolumes". I also clearly have a preference for whitelists over blacklists.

the update boundcondition on the dv doesnt update the condition to true unless the pvc is bound:

The PVC already has a defined requested size, inflating the PVC' with fsoverhead will only be on the PVC' spec and will not reflect on the target PVC, this seems undesired.

Signed-off-by: Alexander Wels <awels@redhat.com> * Disable DV GC by default (#2754) * Disable DV GC by default DataVolume garbage collection is a nice feature, but unfortunately it violates fundamental principle of Kubernetes. CR should not be auto-deleted when it completes its role (Job with TTLSecondsAfter- Finished is an exception), and once CR was created we can assume it is there until explicitly deleted. In addition, CR should keep idempotency, so the same CR manifest can be applied multiple times, as long as it is a valid update (e.g. DataVolume validation webhook does not allow updating the spec). When GC is enabled, some systems (e.g GitOps / ArgoCD) may require a workaround (DV annotation deleteAfterCompletion = "false") to prevent GC and function correctly. On the next kubevirt-bot Bump kubevirtci PR (with bump-cdi), it will fail on all kubevirtci lanes with tests referring DVs, as the tests IsDataVolumeGC() looks at CDIConfig Spec.DataVolumeTTLSeconds and assumes default is enabled.

What this PR does / why we need it:
This PR integrates the use of datavolumes with import and upload populators. In case of having CSI storage instead of using the current path of creating a PVC with import/upload annotation which gets bound before the actual population, we create a PVC that has datasourceref pointing to the appropriate populator (import,upload) and create a volumeuploadsource/volumeimportsource with the right values according to the datavolume. In that case the appropriate populator with be triggered and the population with PVC' process will initiate which will result in having the target PVC bound only after the population succeeded.
This feature is crucial for our product to work seamlessly with DR solutions.
This is a valuable feature also when using datavolumes with VMs that are WFFC which will prevent the need for the current need of "doppelganger" pod to make the PVC bound before starting the VM.
