I'm not a Xen user, nor SLES, but I thought I'd poke around for this.

This seems to be the key.  I found this thread from XenSource:

http://lists.xensource.com/archives/html/xen-users/2010-08/msg00063.html

which suggests your guest kernel's configuration doesn't include MD support.

In your guest, please show the output of:

# zcat /proc/config.gz |grep _MD[=_]
