After the morning seminar of vertex operator algebras in Komaba, I went to the Virtualization Forum 2008 held by VMWare.
I heard the talks of HP, NEC, and Hitachi. They distributed some handouts of the presentations as well as some "commercial bag" of VMWare. At the coffee break, I went to the panel session, to see a blade server of NEC as well as the desktop virtualization by DELL or HP. They did not explain how they were involved with the Xen virtualization or which one was the smartest virtualization machine.
There was also the annoucement of Xen Summit 2009 North America. http://www.xen.org/community/xensummit.html
