Thread-topic: [Xen-devel] Mini-OS and Xen!
Samuel, this means the Ring 0 pages are shared among all the VMs that are 
spawned. Meaning the kernel segment descriptors of each GDT of every VM will 
contain virtual addresses which all point to the same physical address, of that 
of Xen eliminating replication.
