[sles-beta] Admin Server fails to boot on Xen

[Eugen Block]

Hi,

thanks for your response.
I just tried your suggestion. Before the system rebooted for the first  
time I took a look into the file system, the kernel ist there,  
nothings seems to be missing. So I guess I'm facing a different issue.  
What else can I try to figure that out?

Regards,
Eugen
