Ned, this is not true. Fedora10 does have DomU support for Xen, dom0 
support wasent ready in time, the timeline does indicate that Fedora11 
will bring dom0 support back pending xen on paravirt_ops running 
production grade. But then once that happens, it does not really matter, 
  since I'd expect most of Xen to get upstreamed into the mainline 
kernel - making distro support kind of academic.

Also, fedora10 contains all of xend and libvirt support, so if anyone 
wants to bring in a kernel specially built for it, all the userland and 
setup is already in place.

Xen isnt going anywhere - Redhat and others have put in major efforts 
into making it work and as far as I can see, while kvm might be a far 
superior platform, its only an 'alternative' platform. Not the 
replacement one.
