Description of problem:

Created a DV with LVMS, asked 16Mi storage (which is too small), error message is not clear

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

4.18

How reproducible:

Always

Steps to Reproduce:

1. Create a DV:

apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
  name: dv-lvms
  annotations:
    cdi.kubevirt.io/storage.bind.immediate.requested: 'true'
spec:
  contentType: kubevirt
  source:
    registry:
      url: "docker://quay.io/openshift-cnv/qe-cnv-tests-fedora:40"
  storage:
    resources:
      requests:
        storage: 16Mi
    storageClassName: lvms-vg1


2. DV import restarts

$ oc get dv
