Running OS X Mavericks under QEMU with KVM
 

Virtualizing OS X is a thing that can today be done very easily, with VMware and VirtualBox fully supporting it under OS X hosts. But what about virtualizing it using a bare metal hypervisor and QEMU? Under Linux? Finally I've got Mavericks fully working under QEMU (with no extra kexts(!)) and it wasn't easy. Impressive.
