Does it make sense to include Xen in the default list?
I don't know much about Xen but I was under the impression
that it's a special purpose thing that you can only use
as part of a Xen setup, whereas tcg, kvm, hax are all
more-or-less interchangeable ways to run a VM under a
Linux/etc host. Do I have the wrong end of the Xen stick?
