Have you checked the Xen site? Its actually a Citrix product if that helps.
It gets confusing I know- check out wikipedia as well. That will help I
think. And the Xen site (if I remember correctly) is designed with EU's-
in mind not high-level CTO's jargon.
For a start though, something like VMWare and VirtualBox run as an app
on a host (like FBSD). Xen actually runs on the hardware and the guests
run on it. Hence the only project for FreeBSD is for dom0- as special
emulated cpu on Xen.
Thats why Xen usually gets rated faster- its not actually on an OS
because it is one. Thats classified as a type 1. The others have to go
through the host OS first to get something, so it slows them down just a
bit, though the kernel modules help that quite a bit.
HTH clear the fog a bit :) But definitely check out the Xen site- you
can even download the iso to test.
