Create DataVolume NFS:

apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
  name: clone-percap-postgres-vm-83058-l9q6f
  namespace: percap
spec:
  source:
    pvc:
      name: import-percap-postgres-vm-83058-l9q6f
      namespace: percap
  pvc:
    storageClassName: freenas-nfs-csi
    accessModes:
      - ReadWriteOnce
    resources:
      requests:
        storage: 250Gi

Create DataVolume iSCSI:
