`hen` is a Haskell bindings to Xen hypervisor interface. Key feature of

`hen` is that you can use a single library to interact with both Xen3 and

Xen4 hypervisor versions.

The API is split into three levels:

```

|-----------------+-------------------------------------------------------------|

| Level           | Description                                                 |

|-----------------+-------------------------------------------------------------|

| System.Xen.Low  | Provides bindings to raw xenctrl calls.                     |

| System.Xen.Mid  | Defines useful helper functions for acessing System.Xen.Low |

|                 | and allows you to use your favourite impure Monad.          |

| System.Xen.High | Implements the Xen monad, which guarantees safety during    |

|                 | lowlevel operations.                                        |

|-----------------+-------------------------------------------------------------|

```

Example

-------

```haskell

module Main (main) where

import System.Xen (runXenT, domainGetInfo)

main :: IO ()

main = print =<< runXenT domainGetInfo

```

Installation

------------

`hen` requires `xenctrl` headers, Google and unpack any of the two packages bellow:

```

+-----------+-----------------------------------------+

|XCP version|                   Package               |

|-----------+-----------------------------------------+

|1.1        |xen-devel-3.4.2-1.1.0.704.20055.i686.rpm |

|1.5        |xen-devel-4.1.3-1.6.10.498.23551.i686.rpm|

+-----------+-----------------------------------------+

```

After you've unpacked the headers, point `cabal-dev` to them and you're done:

```bash

λ cabal-dev configure --extra-include-dirs=/path/to/headers

```
