Hi Ashok,
But not for any release of SUSE Linux - whether that be SLES or openSUSE 
I'm afraid. I'm not aware of any project internally to implement Xen on 
the SUSE PowerPC release either, so I can only imagine the hassle that 
would be involved in patching a PPC release of SUSE to get it to work 
with Xen.

The presentation you linked to also has links to the Xen wiki for PPC:
http://wiki.xensource.com/xenwiki/XenPPC?action=show&redirect=Xen%2FPPC

It would indicate that the project is still live, and has completed a 
lot of the code to make Xen functional (not all committed upstream 
though), but I wouldn't be comfortable introducing it to a production 
environment. If you're thinking of using it with SLES 10, you'll be 
miles away from a supportable configuration too :-)

Jon
