Sounds like an interesting framework, my quick search didn't unearth any docs for it though? The only reference on Apples website is "we added this to 10.10"
> Hypervisor (Hypervisor.framework). The Hypervisor framework allows virtualization vendors to build virtualization solutions on top of OS X without needing to deploy third-party kernel extensions (KEXTs). Included is a lightweight hypervisor that enables virtualization of the host CPUs.
As with all Mac frameworks, the full headers are embedded in the framework and the headers all have full Javadoc-style API documentation for each function. Since there are only 24 functions in the whole framework, that's probably enough to work it out.
