[fedora-virt] vanilla bridging network

I am trying to define a network tht just bridges the traffic between the virtual machine network and the LAN attached to eth0 No dnsmasq/dhcp as it is difficult to impossible to tie dnsmasq to the master ISC servers on the LAN. It should forward/receive packets like a standard hardware bridge The virtual guests should get their addressing from the dhcp server on the LAN and DNS from the server as well. with the following I can not get dhcp discover reply from the LAN server, nor can I manually code the IP/gateway/DNS and ping the hard address (172.30.2.33) can anyone tell me what I am missing? Vhost and vguest are both CENTOS7 ====================== <networkstatus> <class_id bitmap='0-2'/> <floor sum='0'/> <network> <name>plain</name> <uuid>31f78c2c-257d-4c57-82e5-0c53deadbeef</uuid> <forward mode='bridge'/> <bridge name='virbr1' /> <mac address='52:54:00:b1:34:77'/> <domain name='plain'/> <ip address='172.30.2.1' netmask='255.255.255.0'> <dhcp relay='yes'/> <dhcp enable='no' relay='yes'/> <!-- The relay will not be started if the "enable" property is 'no': --> </ip> </network> </networkstatus> =========================== A routed environment would be acceptable, but bridged is better as it should not be required to change my routing on the gateway router TIA, Bob
