Version-Release number of selected component (if applicable):
4.12

How reproducible:


Steps to Reproduce:
1. Create Windows-10 VM from catalog 
2. Select boot from CD (provide iso)
3. Add blank disk to provide root disk
4. Select mount windows drivers disk

Actual results:
VM gets created but goes into ImagePullBackOff status

Expected results:
VM should be able to pull image from the registry

Additional info:

As a workaround mentioned below,

Link: https://catalog.redhat.com/software/containers/container-native-virtualization/virtio-win/5c8a9ce65a13464733ed0946?architecture=amd64&container-tabs=gti

Run below command on bastion.

oc import-image container-native-virtualization/virtio-win:v4.12.1-3 --from=registry.redhat.io/container-native-virtualization/virtio-win:v4.12.1-3 --confirm


- Stop the VM
- Edit the windows-drivers-disk 
- In containers remove everything after virtio-win.

Before:
registry.redhat.io/container-native-virtualization/virtio-win@sha256:326cbe461af4c34eba009b93a2a103181d90ca225f49be99d2fa152149b685ef

After:
registry.redhat.io/container-native-virtualization/virtio-win

- Start the VM.
