KVM has been around since 2007, so it's hardly new.
Is there an equivalent hypervisor for FreeBSD ? AFAIK, even Xen Dom0
is not possible (please correct me if i am wrong) . So the only option
for virtualization available seems to be virtual-box.
So FreeBSD has _just one_ hypervisor which works. And from my limited
experience with it, i dont think it can be considered 'production
grade'. And virtualbox does not come close to kvm/xen in terms of
performance/management features . Also the whole Oracle thing ...
I was curious about KVM support because of coming across the old port
(2007). What happened to it ?

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

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
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.
