James' USENIX 2007 notes: Tricks with Virtual Machines

Tricks with Virtual Machines
Session Chair: Andrew Warfield, Cambridge University and XenSource

This series of invited talks is about, well, tricks with virtual machines.

Energy Management for Hypervisor-Based Virtual Machines
Jan Stoess, Christian Lang, and Frank Bellosa; University of Karlsruhe, Germany

According to Moore's Law, PC hardware is on pace to approach the thermal density of nuclear reactors within the moderate future.

It's very unlikely this will actually happen, of course, because there are... uhhh... constraining conditions, shall we say... but the real point of this slide was to demonstrate just how much the energy consumption of PCs has grown.

(The speaker had good content in his presentation, but he had an outline of his presentation on index cards, and fell into the trap of reading from the cards instead of presentating.

Xenprobes, a Lightweight User-Space Probing Framework for Xen Virtual Machine
Nguyen Anh Quynh and Kuniyasu Suzaki, National Institute of Advanced Industrial Science and Technology, Japan

This presentation was interesting, but the speaker didn't really say much of anything that wasn't already in the paper.

Virtual Machine Memory Access Tracing with Hypervisor Exclusive Cache
Pin Lu and Kai Shen, University of Rochester

There was a lot of information in this presentation, a good chunk of which was over my head. I'll need to go read the paper off the proceedings CD more carefully...
