Xen users - Jun 2012 - Xen detects duplicated device for SLES 11 DomU

Hi all,

I installed a HVM DomU with SLES 11 on Xen 3.4.3.
If you enter this DomU, you will find both sda and hda after "fdisk
-l".
Actually they are the same device with identical UUID.
It works well for both CentOS and Debian DomUs.

Do you know how to fix that on SLES 11?
Any idea would be appreciated!

Regards,
Cecil
