Desperately Seeking Xen

What's going on with Xen, the open source hypervisor that was supposed to give VMware a run for its money? I can't remember how many IT trade press articles, blog posts and vendor white papers I've read about Xen in the last few years. If I had a dollar for every piece ever published about Xen, I'd be... well, not quite as rich as the Google kids, but still very well off. The vast majority of those articles - including a few I've written myself - take it as an article of faith that Xen's paravirtualizing technical approach and open source business model are inherently superior to the closed source alternatives from VMware or Microsoft.
