Description of problem:
I am unable to create DataVolumes using CDI using URL, local file upload, nor PVC clone. It seems the cdi Pod fails to start, and the DataVolume remains in WaitForFirstConsumer

Version-Release number of selected component (if applicable):
CNV 2.6.0 iib tag 38863
OCP 4.7

How reproducible:
Always

Steps to Reproduce:
1. Set up hostpath provisioner 
2. Create DV using UI Workloads -> Virtualization -> Templates -> CentOS 8
via URL https://cloud.centos.org/centos/8-stream/x86_64/images/CentOS-Stream-GenericCloud-8-20201217.0.x86_64.qcow2
3.

Actual results:
$ oc get pvc,dv -A
NAMESPACE                            NAME                            STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS           AGE

openshift-virtualization-os-images   datavolume.cdi.kubevirt.io/centos8   WaitForFirstConsumer   N/A                   19m


Expected results:

DV progresses to download from URL
