> A few days ago I ran "zypper dup". Since then starting libvirtd fails:

Where do you see that it fails? Is something not working for you?

This log entry informs you that initialization of libnetcontrol failed since
you are using NetworkManager instead of wicked for network management.

Here we can see libvirtd started successfully. What problem are you seeing
other than the notice that interface device management is disabled?
