The dnsmasq processes run by libvirt to serve dhcp for the virtual networks already does this - they listen *only* on the bridge created for their particular network, nothing else. Your problem is that your host system's dhcp server has been configured to automatically listen on all interfaces. So it's not the configuration of the libvirt network that needs to change, it's the configuration of the host system's dhcp server. It needs to be told that it shouldn't automatically listen on all new interfaces, but to just listen on certain specific interfaces. _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
