I didn't say that ! Both the NAT mode and routed mode are usable in many
deployments, regardless of scale.  We simply don't yet have support for
Proxy ARP, but we would like to add this in the future.  Realistically
though, the vast majority of deployments use bridging, so lack of proxy 
arp isn't a huge showstopper. The admin can also easily create a bridge
without any NICs enslaved, set proxy arp for that, and then tell libvirt
to attach guests to that.

Daniel
