Hello, I wrote a small HOWTO how I installed UML on Sarge with kernel 2.6: http://www.xmlvalidation.com/uml_howto_sarge.0.html. I run each uml-guest on a separate LVM volume and under a separate user. Creation, deletion, start, and stop of new guests is done by scripts. They also set up the network, so that the UML guests linux can be reached from outside. If you have any questions, let me know (cc to me since please). Christian
