Summary
The implementation covers the requirements in OCPBUGS-104494 and CNTRLPLANE-4005: HostedCluster labels are propagated to KubeVirt VM and DataVolume templates, and CDI importer-prime pods are excluded from the label and toleration checks. Targeted KubeVirt and e2e utility tests pass.
Required before approval
- Adding labels changes the hashed KubeVirt machine-template spec and can roll out existing KubeVirt NodePools. Please document the migration impact and allow
e2e-aws-upgrade-hypershift-operatorto pass. - Add unit coverage for the modified
EnsureCustomLabelsandEnsureCustomTolerationshelpers, as required byTESTING.md:7.
Non-blocking
The label-copy loop is duplicated for VM and DataVolume labels. Consider using maps.Copy or a shared helper to keep the merge behavior centralized.

Blocking: These labels are part of the machine-template spec passed to the template-name hash in capi.go, so changing HostedCluster.spec.labels changes the template identity and can roll out existing KubeVirt NodePools during deployment. AGENTS.md:40-44 requires reviewing this migration impact and passing e2e-aws-upgrade-hypershift-operator. Please document the impact and add the required gate result before approval.

Blocking: This change and the analogous importer-prime skip in EnsureCustomTolerations below modify two helper functions, but provide no accompanying unit coverage. TESTING.md:7 requires every modified function to have unit tests. Please add focused coverage for the importer-prime exclusions, or document why these e2e helpers are exempt.

This was part of the scope of this ticket however it is more of a separate issue that is already covered in https://redhat.atlassian.net/browse/CNTRLPLANE-4005 (with a PR up already), so I plan on getting rid of this to isolate the issue to that PR specifically.

Non-blocking nit: This repeats the label-copy loop at lines 432-435. Consider using maps.Copy or a small shared helper so both merge sites have identical behavior.

What this PR does / why we need it:
At the moment, the KubeVirt NodePool controller never propagates
HostedCluster.spec.labelslabels onto the KubeVirt data-plane resources it creates. This PR adds label propagation in MachineTemplateSpec() so that user-defined labels fromHostedCluster.Spec.Labelsare applied to these data-plane resources.Which issue(s) this PR fixes:
Fixes OCPBUGS-104494
Special notes for your reviewer:
This has only been tested on main so far but given that this fix isn't in previous versions, it is likely that this bug is still in these versions and will need to be backported
