Xen users - Jan 2009 - hvm phy-disc doesnt boot (file-disc does) (debian dom0, SLES domU)

Hi,

we have a debian etch system running here and it works fine for hvms (winxp) 
and paras (debian etchs).

Today i tried to do a SLES10SP2 setup as hvm (in the future it should run as 
para). I used this config:

---------------
xenserver:/etc/xen# cat gp2backuptest.cfg
kernel             = ''/usr/lib/xen-default/boot/hvmloader''
builder            = ''hvm''
memory         = ''2000''
device_model = ''/usr/lib/xen-default/bin/qemu-dm''
disk                 =  
[''file:/root/SLES-10-SP2-DVD-x86_64-GM-DVD1.iso,hdc:cdrom,r'',''phy:/dev/sdc,hda,w'']
name            = ''gp2backuptest''
vif                 =  [''bridge=xenbr1'']
boot              = ''d''
vnc               = 1
pae              =1
on_crash    = ''preserve''
------------------
As you can see, i tried to use the complete /dev/sdc as hda for the virtual 
machine. 

The install was successfully (The machine bootet from the dvd-image, the hd 
was detected correctly). During the SLES setup i created to partitions (/ 
(450GB) and swap(30GB)) and installed grub in the MBR as well as in /. 

Unfortunatelly, after the first Boot the Systems hangs at grub after loading 
the HVMAssist Bios with the following message: 

----------------
ata0-0: PCHS=16383/16/63 translation=lba LCHS=1024/255/63
ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (18188 MBytes)
ata0  slave: Unknown device
Booting from Hard Disk...
GRUB Loading stage1.5.


GRUB loading, please wait...
Error 2
------------------


xm dmesg shows me:
------------------
(XEN) (GUEST: 8) ata0-0: PCHS=16383/16/63 translation=lba LCHS=1024/255/63
(XEN) (GUEST: 8) ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (18188 MBytes)

(XEN) (GUEST: 8) Unknown opcode at 0000:22B5=0x22B5
(XEN) (GUEST: 8) Halt called from %eip 0xD404A
-------------------

What i am wondering about are the 18188 MBytes. 

I tried another hdd - with the same result. BUT: When i do exactly the same 
setup but with a image-file as hda, everything works well. 

What am i doing wrong? Big thanks for any suggestions!

Best regards,

Roman Lehnert
