There are not a lot of options but VirtualBox works pretty excellently. There's also BHyVe and you can always use Qemu :) The lack of hypervisor support is really more due to people not keeping up with the porting work. I would love to see Xen actively supported but I think BHyVe is going to be where the most work gets done.
