That's funny: I understand so much your situation. François 2006/6/28, Lars Erik Dangvard Jensen <lars@xxxxxxxxxxx>: Ok, I think I have all these modules static compiled in my dom0 kernel (http://www.dangvard.dk/xen3/dom0config). But I'm not sure what exactly the modules are called in the dom0 config file. E.g. tun is called CONFIG_TUN etc. ***5 minutes later....*** OMG! I see that I have physically connected the servers eth0 to a wrong cable, a wifi ethernet adapter (not a switch!), which is ONLY assigned one IP-address...! LONG LIVE CABLE CHAOS ON MY FLOOR! Sorry, Francois, to waste your precious time. But now this kind of problem also reached the xen-user list! :S I could have made something up, to hide my own mistake... but I think it's pretty funny that I've spend 2 days searching for at problem that wasn't there. I really hope it amuses others on the list a bit ;) Thanks for your help.
