xhyve, a lightweight OS X virtualization solution

The xhyve hypervisor is a port of bhyve to macOS. It is built on top of Hypervisor.framework in OS X 10.10 Yosemite and higher, runs entirely in userspace, and has no other dependencies. It can run FreeBSD, some Linux distributions, and Windows 10 and may gain support for other guest operating systems in the future.
