Temporary fixe
As a temporary solution, which I know is not the best, is to put the usb controller from the sys-usb to the sys-net. Now it’s working as expected.
Where the problem is
It’s not a driver problem related because fedora 33 don’t have any problem to see the interface but something is wrong when I’m doing qvm-usb attach sys-net sys-usb:3-4.1
that make it not work
