Hi, > I think you can either configure the guest with static information or > use DHCP. I may have missed something in the question though. > No you didn't. Maybe my question don't make sense... But It's exactly what I'm doing now. So, if I need to replicate about 20 guests, each one with your own static IP, I can use DHCP and enforce IP's using mac addr. But, is it possible to do this using the Xen configuration files for the vm's? Just to get somethings a bit simple avoiding DHCP. And thanks for your answer. -- Walter.
