Crate hypervisor

This is a Rust library that taps into functionality that enables hardware-accelerated execution of virtual machines on OS X.

It binds to the Hypervisor framework on OS X, and exposes a safe Rust interface through the hypervisor module, and an unsafe foreign function interface through the hypervisor::ffi module.

To use this library, you need

• OS X Yosemite (10.10), or newer

• an Intel processor with the VT-x feature set that includes Extended Page Tables (EPT) and Unrestricted Mode. To verify this, run and expect the following in your Terminal:

  $ sysctl kern.hv_support
  kern.hv_support: 1
