The Xen™ virtual machine monitor

Our 2003 SOSP paper "Xen and the Art of Virtualization" describes the design of the 1.0 release of Xen. However, there's been some fairly major changes to the way Xen does I/O in the 2.0 release. Read together, the following documents give a decent architectural overview:

Xen and the Art of Virtualization describes the architecture of Xen 1.x. Published at SOSP 2003
Xen and the Art of Repeated Research is an independent paper verifying our SOSP results (written by a group at Clarkson University),. Published at FREENIX 2004
Safe Hardware Access with the Xen Virtual Machine Monitor describes the new I/O infrastructure in Xen 2.0. Published at the OASIS ASPLOS 2004 workshop.
