[Virtualization] VMI does not exist, VM status stopped

I make a trial case about virtualization in OCP Openshift 4.12. What I have done so far:
1. Install Cluster Operator RedHat Virtualization until it was done (on default namespace openshift-cvn)
2. I created VM using virtualization catalog, with boot disk refer to fedora URL qcow2. The setting for CD Room and Disk are Blank (Create PVC)
3. After I clicked Create VM, it is just stopped without any error found
4. I tried the "start" menu and got no response
5. I tried using cli, oc get vms -o yaml and there was error:

status:
conditions:
- lastProbeTime: "2024-10-08T06:34:02Z"
lastTransitionTime: "2024-10-08T06:34:02Z"
message: VMI does not exist
reason: VMINotExists
status: "False"
type: Ready
printableStatus: Stopped
volumeSnapshotStatuses:
- enabled: false
name: rootdisk
reason: PVC not found
- enabled: false
name: cloudinitdisk
reason: Snapshot is not supported for this volumeSource type [cloudinitdisk]
- enabled: false
name: installation-cdrom
reason: PVC not found

Question, why the VM is not started? what is lacking in my instalation steps? I find that it lacks of discussion about Red hat Virtualization that uses kubevirt
