Indeed - this is also the way I have libvirt configured, and my guests are getting IPv6 addresses automatically from radvd running elsewhere on my LAN. For reference, here is how I configure the network: # cat /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes DELAY=0 NM_CONTROLLED=no and then I just connect each guest directly to the bridge: <interface type='bridge'> <mac address='52:54:00:12:ab:a9'/> <source bridge='br0'/> <model type='virtio'/> </interface> http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_physical_device.22.29 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.
