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.
