SLES10 Beta11?  RC1?  What tools are you using to create the image?  The 
YaST Virtual Machine Management module makes image creation fairly 
straight forward.  There have been a few issues when installing from DVD 
or CD, but I think most of these are fixed in RC1.  Network installs 
have worked well for some time.  Please provide additional information 
on your problems.
For your domU network issues, ensure the firewall is configured 
properly.  Perhaps you can disable it as a starting point.  Also ensure 
you specify a MAC address in your domU configuration file.  If not, Xen 
will generate a new one each time the domU is activated, causing the 
guest to see a new (unconfigured) network interface.
See /usr/share/doc/packages/xen/README.SuSE for additional notes.  Also 
check out the Xen Technical Preview site for latest RPMs, docs, mailing 
list, etc.

Post any issues / questions you have concerning Xen and SLES10 to the 
mailing list.

Jim
