First... my system without Xen running: I have two ethernet interfaces, eth0 and eth1, where eth1 is connected to the internet and eth0 is my private NAT'd network; this system is my firewall. I'm using Firestarter to configure things and I'm able to connect FC5 to any location I wish, internal and external, and my internal machines are able to connect to the firewall as well as the internet. Both eth0 and eth1 are configured as static IPs, and all machines in my private network are static IPs ( Now, my firewall is also running other services and I'm interested in moving these services to their own virtual guest machines eventually. First though, I think I should be able to boot into a Xen-enabled kernel and have the same level of functionality I currently have without Xen. My kernel boots fine and seems to operate but I'm not able to do much with networking... I can't connect to any machine (through eth0 or eth1) from my Xen0 kernel, and my private network machines cannot connect to my firewall or through my firewall. I see many posts where people have guest O/S networking issues... but in my case I haven't even reached the stage of trying to create a guest O/S. Thanks for any tips towards my getting this resolved! </BODY></HTML>
