Interestingly, in netplan-sriov-apply.service I can see this: "Apr 16
15:44:44 romano netplan[1171]: failed parsing sriov_totalvfs for
ens7f1np1: [Errno 2] No such file or directory:

Whereas it should be:

ubuntu@romano:~$ cat /sys/class/net/ens7f1/device/sriov_totalvfs 
8

ubuntu@romano:~$ sudo systemctl status netplan-sriov-apply.service
