As far as I'm aware, Xen virtualisation is a technology for Intel and 
AMD class processors and therefore not applicable to PowerPC 
architectures. I'm not very familiar with PPC architecture - doesn't it 
have some form of virtualisation native to itself?

These questions are all probably moot due to the above, however, SLES 10 
already includes the required Xen kernel and tools. (SUSE Linux 10.0 
which is now very old doesn't have an up to date implementation and 
should be avoided. openSUSE 10.3 is available and has a more recent

Obviously the whole technology is not available for PowerPC. Xen 
consists of a hypervisor (Virtual Machine Monitor), and various tools 
and utilities to control that hypervisor.
