As far as I know, the only features that KVM lack over Xen are fault-tolerance (though there are QEMU patches that implement it) and driver domains.

And -- if you consider the full QEMU/KVM/guest-driver stack -- 3D rendering support.

Oh, and does it have properly working USB support yet? Last time I tried, it couldn't do USB 2.0, but I haven't needed to use a USB device with one of my VMs in years.

It can do USB 2.0 (with companion USB 1.1 controllers) and USB 3.0 too.

Anyhow, qemu is shared between Xen and KVM, so that part of the feature set is shared (especially since both Xen and KVM can now use upstream qemu rather than their own forks).
