vmware and xen are around for a long time. KVM is the new one in
production context.

IMHO gpl  is not the main problem.  KVM is a linux kernel module that
manage virtual contexts.
It works with an io hypervisor (virtio) and and hardware emulator
(qemu). So porting
KVM to FreeBSD has no sense. The need is a tool to manage hardware contexts.
This tool is  BHyve, I think.

Let's have a look at what we currently get.
- Qemu is working but does not support vt.
- VirtualBox just works and support vt
- Jails are becoming real containers
- NetApp is working on a new hypervisor
- A virtio driver should be soon available
- Xen is supported has a domU
- a set of useful features like cpuset, vnet, zfs, hast, rctl, geom
are now available

So what is missing ? Maybe an unified manager ala libvirt ? Some fs
improvement like
distribution, iscsi ? A bsd style cluster manager ? A lot of things
are missing most of them are
configuration  tools or stabilization, finalization of existing
projects. But not an other
hypervisor, I think.
