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. |
|-----------------+-------------------------------------------------------------|
module Main (main) where
import System.Xen (runXenT, domainGetInfo)
main :: IO ()
main = print =<< runXenT domainGetInfohen 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:
λ cabal-dev configure --extra-include-dirs=/path/to/headers
