Enforcing performance isolation across virtual machines in Xen
TL;DR: The design and evaluation of a set of primitives implemented in Xen to address performance isolation across virtual machines in Xen are presented and it is indicated that these mechanisms effectively enforce performance isolation for a variety of workloads and configurations.

Measuring CPU overhead for I/O processing in the Xen virtual machine monitor
TL;DR: This work presents a light weight monitoring system for measuring the CPU usage of different virtual machines including the CPU overhead in the device driver domain caused by I/O processing on behalf of a particular virtual machine.
Autonomic Virtual Machine Placement in the Data Center
TL;DR: A high level overview of a virtual machine placement system in which an autonomic controller dynamically manages the mapping of virtual machines onto physical hosts in accordance with policies specified by the user is presented.
XenMon: QoS Monitoring and Performance Profiling Tool
TL;DR: A performance case study is presented that demonstrates and explains how different metrics reported by XenMon can be used in gaining insight into an application’s performance and its resource usage/requirements, especially in the case of I/O intensive applications.
