Thank you all, I solved this problem myself. It was necessary to start the iptables service:
sudo systemctl start iptables.service
sudo systemctl enable iptables.service
sudo systemctl restart libvirtd.service

First: please post text as text - not as images.
Another option is to setup a bridge.

Found a complete solution to this problem, you need to edit the configuration file:

sudo nano /etc/libvirt/network.conf

write the following:
firewall_backend = "iptables"

The problem is completely solved, the topic can be closed
