Indeed, the spokesperson said that one such 'experimental' project was based on a forked Linux kernal 'with no support from Fedora.' ... As a reader pointed out, since this is open source, if you want better support for Xen on Fedora, you are free to built it yourself. But here's hoping that Xen.org, or the users at Fedorapeople.org are willing to lend a hand."
