Hi

I had a brief look at the routing scripts in /etc/xen/scripts. Essentially the main script turns on ip forwarding in dom-0, and the dom-U vif script seems to configure a 169.254.1.0 address for each vif (auto-configure address, I think), then enable proxy ARP on the vif.

Some questions: How do remote machines pick up routing information for the dom-U's? Do I have to run a routing protocol in dom-0 (maybe with zebra) so that remote machines can 'see' the dom-U's?

Could someone maybe explain the details of the ifconfig <vif> 169.254.1.0 ... and what the proxy ARP stuff does?

Thanks
Roland
