Autonomic Virtual Machine Placement in the Data Center Chris Hyser ([email protected]) Bret McKee ([email protected]) Rob Gardner ([email protected]) Brian J. Watson ([email protected]) Hewlett Packard Laboratories December 11, 2007 Abstract We present 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. By closely monitoring virtual machine activity and employing advanced policies for dynamic workload placement, such an autonomic solution can achieve substantial cost savings from better utilization of computing resources and less frequent overload situations. 1 Introduction Virtualization allows a great deal of flexibility in the provisioning and place- ment of servers and their associated workloads in a data center. The problem of provisioning virtual machines is receiving a great deal of attention[1, 2, 3], while placement is often a relatively static manual process. A virtual machine using only virtual resources provides a computational encapsulation that may be moved between physical hosts in its entirety. A feature enabled by this en- capsulation is the capability to migrate a running virtual machine from one physical host to another without a significant interruption of service[4]. This technology is currently available in VMware’s ESX product[5] and Xen[6], and it is anticipated in Microsoft’s Viridian product[7]. This document refers to this technology as live migration . Live migration imposes certain restrictions on the source and destination physical hosts, possibly including requiring compatible virtualization software, comparable CPU types, similar network connectivity, and the use of shared storage. The exact requirements depend on the virtualization software[8, 9]....
