Ok, I''ve completely reinstalled Xen and I am still encountering the most curious problem. I set up a virtual network of eight domains: three are on a virtual DMZ network (10.0.1.0/24), four are on a virtual internal network (10.0.2.0/24), and a router connects the two. All the domains can ping each other and traceroute-ing between them shows the proper network structure (first hop: router, second hop: domain in other network). However, when I log on to one of the domains (eg. 10.0.2.40) and use nmap to scan the network for machines (eg. nmap 10.0.2.0/24), my whole computer reboots in the middle of the nmap command. I''ve attached the output from nmap up until it reboots my machine, any ideas or suggestions would be greatly appreciated.
