Kernel Summit 2005: Virtualization
VT / Pacifica combined with Xen is an interesting topic.
Vanilla Xen gives you near native performance in virtual machine
*already* - hardware extensions aren't going to provide any immediate
improvements for OSes that run natively on Xen (Linux, BSD, etc) because
you can't really do better than the unvirtualised performance.
The real benefit of hardware support for virtualisation in Xen's case is
that it will enable *unported* operating systems to run, and achieve
reasonable performance. The primary benefit will be the ability to run
Windows. You'll also be able to run old, unported versions of Linux on
Xen in order to migrate old servers completely onto Xen with no
configuration changes.
