There are things I dislike intensely about KVM, specifically the lack of network configuration tools for setting up the requisite bridged networking and the resulting configuration chaos, especially if you want pair-bonded network ports. If I see one more such configuration written by a scripting monkey boy who *never tried disconnecting each of the cables to be sure it worked*, I'm going to be an unhappy camper.
I'm also looking at the speed comparisons of KVM and Xen published at http://blog.xen.org/index.php/2011/11/29/baremetal-vs-xen-vs-kvm-redux/ and followup at http://www.phoronix.com/scan.php?page=news_item&px=MTAyMTk. And overall, the performances between the latest manually patched kernels with Xen and the latest KVM are..... hardly significant for typical use. So is it worth the extra sweat and tears to maintain the distinct architecture. Do you really see enough benefit to justify the work? And what makes you think that our favorite upstream vendor will revisit Xen support for release 7?
