Well Xen does paravirtulization like you described (and I agree
something like that is more flexible then jails, if supported by other
operating systems). DragonflyBSD has its own flavor of virtualization
similar to user mode Linux, but it has greatly diverged from FreeBSD so
it't probably not trivially portable.

Or do you mean something like this:

The version of kvm ported to FreeBSD has no paravirtualization
support. Paravirtualization is, as far as I know, still an
experimental feature on Linux, not present in the mainline tree.
I am not aware of FreeBSD support for the kvm hypercalls that are
being introduced in the kvm experimental trees.

By now kvm is really just a full virtualization solution.
