I completed the new Xen Directions page on Xen.org at http://www.xen.org/xendirections/xendirections_june09.html. Not all the slides and videos are availalable yet as I need approval from the speakers to post both; however there is some interesting information already available. As the speakers get back to me over the next few days I will update the page links.
All the presentation slides are in English and the only video in German is Frank Kohler from Citrix; however, his slides are excellent and worth a look.
