I should add - getting UML set up was pretty easy, but it's by no means a point-and-click deal like VMWare and/or Virtualbox. As long as you're somewhat comfortable with the commandline and familiar with linux networking, it should be no problem. I gave Xen a try before settling on UML, and found UML a lot more simple to get going. -erik -- Erik Anderson http://andersonfam.org
