Hello,
As I understand the Hypervisor should run in Ring 0 of the x86 , and 
the domains (Domain0 and DomainU) should work in Ring 1. 

I was a bit curious where in the code this assiging of Ring 0 to Xen
and Ring 1 to dom0/domU is done ?
I had tried to look under arch/xen/i386 and didn't find.

Is it in the assembler *.S files ?

Regards,
John
