Libnetcontrol failed to initialize

I’m new to OpenSuse Tumbleweed and I’m trying to install virt-manager.

I know there’s already a post about this problem but the answer is for Leap and I couldn’t find the settings here on Tumbleweed. Another way out was to reinstall the system, something I’ve done twice and still having the same problem.

First I installed it through zypper with the command:
sudo zypper install libvirt virt-manager

Then I installed the rest of KVM through YaST.

When I start libvirtd it gives me this warning:

May 31 23:39:26 opensuse libvirtd[2365]: Failed to initialize libnetcontrol. Management of interface devices is disabled

When I open Virt-Manager, it has:
QEMU/KVM - Not Connected.

From the research I did here on the Forum and on the internet, I couldn’t solve my problem yet, could you help me?

Could you please run virsh net-info default and show the output.
