"""
This API abstracts all calls to any hypervisor type.
This API is split in four parts:
* Global Interface
* Libvirt Wrapper
* KVM, XEN, ... hypervisor interface
* Exceptions
Every entity in the hypervisor library has a common ancestor
:class:`interface.Host`.
The inheritance diagram shown below reflects the relationship between
each class.
