Efficient Idle Desktop Consolidation with Partial VM Migration

Abstract
Recent surveys have found that enterprise desktops spend most of their time idle.  Despite the fact that idle PCs consume up to 60% of their peak power, these systems have been found to remain powered in order to allow applications with network presence to remain online (e.g. IM, VoIP, remote desktop). Virtual machine (VM) consolidation has been proposed as a solution for this problem by using virtualization to migrate the user's computational environment to a server while the desktop is suspended to low power mode.  Unfortunately, energy-oriented full VM migration does not scale well in office environments; desktop VMs require large amounts of memory, resulting in low consolidating  ratios, and network congestion that lead to long resume latencies.

I will present Partial VM Migration, an approach that transparently migrates only the working set of an idle VM, and show that this approach is better suited to enterprise offices.  Partial VM Migration is effective at reducing energy use of idle desktops, leads to small migration sizes and migration latencies, and provides high VM consolidation ratios on the server.
