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

It is a fork of [hypervisor-rs](https://github.com/saurvs/hypervisor-rs) and modified for the development of [uhyve](https://github.com/hermit-os/uhyve).

Derived from [ahv](https://github.com/Thog/ahv), we added the support of Apple's Hypervisor Framework on Apple Silicon.

It binds to the [Hypervisor](https://developer.apple.com/documentation/hypervisor) framework on OS X, and exposes a safe Rust interface through the `hypervisor` module, and an unsafe foreign function interface through the `xhypervisor::ffi` module.

## Prerequisites

To use this library, you need

* macOS 10, or newer

* An Intel processor with the VT-x feature or an Apple Silicon processor with virtualization support. To verify this, run and expect the

following in your Terminal:

  ```shell

  $ sysctl kern.hv_support

  kern.hv_support: 1

  ```
