When a MAC address conflict occurs between the source VM being migrated and an existing VM on the destination (CNV/OpenShift) cluster, the failure is not clearly surfaced at the Plan or Migration level. Instead, the error is buried deep in the Plan YAML under the VM status section, specifically within the ImageConversion step under status.migration.vms[].pipeline[].error.reasons.
As a result, users do not see the conflict reflected in the overall failure reason of the plan, leading to difficulty in diagnosing the root cause without manually inspecting the full Plan YAML.
main error from the plan :
Source VM has a mac address conflict with one or more destination VMs: [openshift-mtv/500gb-offload]
