Routed / Proxy ARP.

vif-route assigns an IP to the appropriate vif interface. The IP's of the VM are routed through the vif interface.

It's really nothing special... routing is actually less complex than bridging IMHO.

Is this perhaps a 2.6.16 kernel bug? Are there any dis-advantages to upgrading to or .10-rc?
