Forum OpenACS Q&A: Re: Re: Solaris Zones vs. Xen vs. Vanilla Debian
I think Cathy is using User Mode Linux. I have ruled out UML based on research and problems getting a testing environment up.
Getting a test version of Xen running was simple ( http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads.html ). In fact I had the Xen Demo up and running before I finished reading through the license and downloading the second Solaris 10 CD from Sun (iirc there where ~6).
