Xen 3.0 Supports AMD-V/Pacifica

With hardware CPU virtualization as provided by Intel VT and AMD Pacifica technology, the ability to run an unmodified guest OS kernel is available. No porting of the OS is required, although some additional driver support is necessary within Xen itself. Unlike traditional full virtualization hypervisors, which suffer a tremendous performance overhead, the combination of Xen and VT or Xen and Pacifica technology complement one another to offer superb performance for para-virtualized guest operating systems and full support for unmodified guests running natively on the processor. Full support for VT and Pacifica chipsets will appear in early 2006.
