From Thiago Camargo Martins Cordeiro in Xen-Devel (http://markmail.org/thread/2t2cbfjkxz6awnzu):
I’m happy to announce everyone that is available a newer version of the Xen Live CD, the version 2.0.
It’s entirely based on latest version of the stable Debian, the recently released 5.0.
The Live CD Xen has several different examples, illustrating some situations and solutions. For example, two versions of Xen, 32 and 64 bits, 32 and 64 bits dom0, HVM machines, PVM machines, examples of PyGRUB, and more!
Visit the Wiki page http://wiki.xensource.com/xenwiki/LiveCD to download it today!
** Special thanks to Thiago for his great efforts in putting together a new LiveCD for the community. I believe that everyone will find this valuable!
