Comment 4 Satyajit Bulage 2022-12-22 10:23:14 UTC 
Verification Steps:
1. Created VM on SRIOV operator installed BM cluster.
2. VM is not using any SRIOV interfaces not the secondary one.
3. Observed virt-launcher pod logs for more than 20mins.
4. Also, checked logs via CLI
   i. oc logs virt-launcher-vm-example-spj4w -f | grep -i SRIOV

Conclusion: Warning log is not appearing in the virt-launcher pod of VMI.

Env: 
OCP-4.11.20
CNV-v4.11.2-10
SRIOV : 4.11.0-202208301406
