The USENIX Annual Tech Conference 2009 is scheduled for June 14-19, 2009 in San Diego, CA. Both Wenjin Hu and Zach Shepard from Clarkson University who ran the Xen Hypervisor tutorials at LISA 2008 will be running the Virtualization Tutorials at this event with a focus on open source Xen. I encourage everyone interested in learning more about open source Xen in a hands on training environment to attend.
