I removed network manager and have this in /etc/network/interaces: # eth2 managed by bridge and not otherwise mentioned
auto br0 iface br0 inet dhcp bridge_ports eth2 That seems to work with the kvm-ifup script provided by wheezy qemu-kvm. Note I have not rebooted since setting this up, and so it's possible that might expose problems. Thanks everyone for your help. Ross P.S. I was wondering if tap0 needed to be setup both in interfaces and kvm-ifup; evidently it does not.
