I used the Xen 2.0 and it holds after requesting some modules. With Xen 3.0 
it boots without that.

First I tried the SuSE 9.3 Xen kernel, but that one stops after "NET: 
Registered protocol family 16"...

My version is from 2005-09-14 04:22 (xen-unstable-install-x86_64.tgz). Maybe 
I have used the wrong one? Do I need some special configuration for SMP? 
These were my first steps, so I tried the binary ones. Should I make my one 
Xen kernel?

Maybe a "cat /proc/cpuinfo" helps out?

Thanx for help,
Sven.
