I've heard mixed reviews of that. It is probably not quite ready for production, but it will be interesting in the future.

Just to add to the reviews - I've had difficulty in getting Bhyve to consistently work. Sometimes the VM will boot fine, others it will just crash halfway into the boot cycle. When it works, it's good. It has a few years before it gets to Xen/KVM levels of stability, but it's a really good start.
