Verified on
CNV 4.12.0-758
SR-IOV 4.12.0-202212140155
virt-handler v4.12.0-252


1. Create a basic Fedora VM with no SR-IOV interfaces (or any secondary interface) on a bare-metal cluster with SR-IOV installed.
2. Follow the virt-launcher log for ~15 minutes:
$ oc logs virt-launcher-vm-fedora-h4fg5 -f | grep -i IOV

No output found.
