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

[Eugen Block]

Hi everyone,

I'm currently trying to upgrade from cloud 5 to cloud 6 beta. During  
installation of the Admin server I'm facing some difficulties. The  
admin server is supposed to run as a xen-guest on a SLES11-SP4 host.  
The installation itself went smoothly, but after reboot the vm gets  
stuck in the grub command line. It is possible to boot the vm, though:  
in grub cmd I just have to execute these commands manually, and then  
it boots successfully (until next reboot):

--- cut here ---

set root='hd0,msdos3'
linux   /vmlinuz-xen root=UUID=e557cc68-5b12-48a2-a15f-da9b2c75dfcb  
192.168.103.5 resume=/dev/xvda1 splash=silent quiet showopts
initrd  /initrd-xen
boot

--- cut here ---


I have been able to install SLES12 on a xen guest before, but it fails  
now on SLES12-SP1.
An excerpt of the xen config file for the admin server:

--- cut here ---

builder="linux"
kernel="/usr/lib/grub2/x86_64-xen/grub.xen"

--- cut here ---

nameserver is also set.
If you need any further information to analyze I would be happy to  
provide missing info.

I would appreciate any help.

Regards,
Eugen
