The article explains the difference in detail. Now, I can understand why it's too difficult to run Java Web server on OpenVZ for evaluating TPCW benchmarks.

Linux Gains Two New Virtualization Solutions 
By Tyler Bletsch - Saturday, July 21, 2007, 10:38 AM - Systems, Software news
By way of slashdot, we find that the Linux kernel (2.6.23 and up) now sports three virtualization techniques out-of-box: KVM, Xen (just merged), and Lguest (also recently merged).

Lguest in particular looks interesting, as it doesn't require virtualization hardware support (like KVM), but is as simple as a single modprobe (as opposed to the Xen behemoth). Performance isn't too great right now, though (-30%).

Clarkson University Prof Jeanna Matthews has one of the best round ups of system papers. It comes as no surprise that she received her training at Berkeley. Kudos to her.
