Description of problem:
VM (RHEL-8) import remain forever at 75% progress (in UI).
This is for target storage NFS/Ceph-RBD/Block.

Found an error only in the vm import controller log:

Version-Release number of selected component (if applicable):
$ oc get   csv -n openshift-cnv kubevirt-hyperconverged-operator.v2.5.0 -oyaml | grep createdAt
    createdAt: "2020-10-06 07:31:33"


How reproducible:
100%

Steps to Reproduce:
1. Add vddk-init-image to the v2v-vmware conigMap.

2. Add a Secret:

cat <<EOF | oc create -f -
---
apiVersion: v1
kind: Secret
metadata:
 name: vmw-secret
type: Opaque
stringData:
 vmware: |-
   # API URL of the vCenter or ESXi host
   apiUrl: "https://<VMware IP address>/sdk"
   # Username provided in the format of username@domain.
   username: administrator
   password: Heslo123!
   # The certificate thumbprint of the vCenter or ESXi host, in colon-separated hexidecimal octets.
   thumbprint: 31:...:30
EOF

3. Add External mapping:

cat <<EOF | oc create -f -
apiVersion: v2v.kubevirt.io/v1beta1
kind: ResourceMapping
metadata:
 name: example-vmware-resourcemappings
 namespace: default
spec:
  vmware:
    networkMappings:
    - source:
        name: VM Network # map network name to network attachment definition
      target: 
        name: pod
      type: pod
    storageMappings:
    - source:
        id: datastore-12 
      target: 
        name: nfs < Or Ceph-RBD/Block
EOF

4. VM import create:

cat <<EOF | oc create -f -
apiVersion: v2v.kubevirt.io/v1beta1
kind: VirtualMachineImport
metadata:
  name: vmware-import-1
  namespace: default
spec:
  providerCredentialsSecret:
    name: vmw-secret
    namespace: default # optional, if not specified, use CR's namespace
  resourceMapping:
    name: example-vmware-resourcemappings
    namespace: default
  targetVmName: vmw-import
  startVm: false
  source:
    vmware:
      vm:
        id: 42037aff-4d6f-cf89-7979-e98cbc406c0e <-- UUID of RHEL-8 VM
EOF

Expected results:
1. VM import progress should succeed.
2. a message should be displayed, explaining why VM import is not progressing.
