Verified on 4.14.1

steps:

1. create dv from ocs to block volumemode:
apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
  name: dv-source-ocs
spec:
  source:
      http:
         url: "http://cnv-qe-server.rhos-psi.cnv-qe.rhood.us/files/cnv-tests/cirros-images/cirros-0.4.0-x86_64-disk.qcow2"
  storage:
    resources:
      requests:
        storage: 1Gi
    storageClassName: ocs-storagecluster-ceph-rbd-virtualization

2. cloned the dv to hpp fs:
apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
  name: cloned-dv
  namespace: default
  annotations:
    cdi.kubevirt.io/storage.bind.immediate.requested: 'true'
spec:
  source:
    pvc:
      name: dv-source-ocs
      namespace: default
  storage:
    storageClassName: hostpath-csi-basic

3. Clone successful and pod didnt failed

Note: verified also for vice verse, fs -> block
