Live Migration of Virtual Machines
- In Proceedings of the 2nd ACM/USENIX Symposium on Networked Systems Design and Implementation (NSDI
, 2005
"... Migrating operating system instances across distinct physical hosts is a useful tool for administrators of data centers and clusters: It allows a clean separation between hardware and software, and facilitates fault management, load balancing, and low-level system maintenance. By carrying out the ma ..."

Improving Xen security through disaggregation
- Proceedings of the Fourth ACM SIGPLAN/SIGOPS international conference on Virtual Execution Environments
"... Virtual machine monitors (VMMs) have been hailed as the basis for an increasing number of reliable or trusted computing systems. The Xen VMM is a relatively small piece of software – a hypervisor – that runs at a lower level than a conventional operating system in order to provide isolation between ..."

VMM-independent graphics acceleration
- In Proceedings of VEE 2007
, 2007
"... This paper describes VMGL, a cross-platform OpenGL virtualization solution that is both virtual machine monitor (VMM) and graphics processing unit (GPU) independent. VMGL allows applications executing within virtual machines (VMs) to leverage hardware rendering acceleration, thus solving a problem t ..."

The Inevitability of Xen
, 2005
"... Xen is a virtual machine monitor (VMM) that we have developed at the University of Cambridge over the past 5 years. As a VMM, Xen allows a single physical computer to be partitioned into a set of isolated virtual computers, each running their own operating system and applications. Xen has received a ..."

-ditions of such high consolidation: CPU schedulers that are agnostic to the communication behavior of modern, multi-tier applications. We develop a new communication-aware CPU scheduling algorithm to alleviate this problem. We im-plement our algorithm in the Xen VMM and build a proto-type VHP on a cluster of servers
High Performance VMM-Bypass I/O in Virtual Machines
, 2006
"... Currently, I/O device virtualization models in virtual machine (VM) environments require involvement of a virtual machine monitor (VMM) and/or a privileged VM for each I/O operation, which may turn out to be a performance bottleneck for systems with high I/O demands, especially those equipped with m ..."
