Re: Network denied access

Thank you for taking the time to respond. I want to mention that I don't speak English, and it's difficult for me to understand using a translator. In the file */etc/libvirt/libvirtd.conf*, I have the following: access_drivers = [ "polkit" ] The *virtqemud* and *virtnetworkd* services are not installed. I used the version from the Debian 12 repositories. systemctl status virtnetworkd.socket Unit virtnetworkd.socket could not be found. systemctl status virtqemud.socket Unit virtqemud.socket could not be found. In the file */etc/libvirt/qemu.conf*, the default configuration is present. Best regards.
