Thanks to Valentin Höbel for his efforts in translating the Xen.org Overview slides from English to German. The slides are now available for everyone to use at http://www.xen.org/files/Marketing/XenOverview_german.pdf or at SlideShare: http://www.slideshare.net/xen_com_mgr/xenorg-overview-german.
I expect to get these slides translated to other languages over the next week or so and will be posting those updates to Xen.org and SlideShare.
