Doesn't this allow the VMs to have unrestricted access to anything on the host ? At a libvirt POV, the NAT and routed zones should be identical, with the only difference being whether masquerading is applied. In terms of VM -> host, we still only want to allow the small set of services, dns, dhcp, ssh AFAIK.
