Bug conversion log

Description of problem:
While trying to import VM from VMware to CNV with disk size that bigger than the available storage space in the cluster - there is no error in the Events page, the importing is started and at some point gets stuck


Version-Release number of selected component (if applicable):
CNV 2.2.0-10


How reproducible:
100%


Steps to Reproduce:
Migrate VM (vmware -> cnv) who has larger disk size then the available space in cluster

Actual results:
There is no error and at some point the importing doesn't progress


Expected results:
The importing won't be started OR will fail with a relevant error message in the Events page
Please see BZ bug: https://bugzilla.redhat.com/show_bug.cgi?id=1721504


Additional info:
The import has been running for 2.5 hours (after it we stopped the import).
In the saved log - it seems that after 2 hours run it stopped reading disk, and instead in the log there are repeated messages:
2019-12-24 07:25:06,611 - root - DEBUG - Accessing Kubernetes on: https://172.30.0.1:443/api/v1/namespaces/default/pods/kubevirt-v2v-conversion-vm-100gb-bclln
2019-12-24 07:25:06,622 - root - DEBUG - HTTP response code 200
2019-12-24 07:25:06,622 - root - DEBUG - Updating progress in POD annotation

Comment 1 Maayan Hadasi 2019-12-24 10:02:47 UTC 
Additional info (CNV v2.2.0-10):
It is not possible to import VM on the environment after bug reproduction.

Delete the "importing" VM (by conversion log and annotation, the import is stuck) -> delete its PVCs/PVs -> run another import -> 
VM, PVCs and conversion pod status is pending, and the VM Events page shows this error message:
"pod has unbound immediate PersistentVolumeClaims (repeated 3 times)"
