[libvirt-users] routed network and physical interface

Hello, I've created a routed network that forwards to a physical interface: <network> <name>default</name> <forward dev='eth0' mode='route'/> <mac address='52:54:00:f2:5b:4f'/> <ip address='192.168.100.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.100.10' end='192.168.100.20'/> </dhcp> </ip> </network> When this network is started, the iptables rules are associated with eth0, as expected. However, the "virbr0" bridge interface that is create automatically does not contain the eth0 interface. I have to manually run "brctl addif virbr0 eth0" so the guests can communicate with the outside. I was under the impression libvirt would add the physical interface automatically, based on the <forward> definition. Is it how it should work? Giovanni
