This module (mostly) uses the XenAPI to manage Xen virtual machines.
Big fat warning: the XenAPI used in this file is the one bundled with
Xen Source, NOT XenServer nor Xen Cloud Platform. As a matter of fact it
*will* fail under those platforms. From what I've read, little work is needed
to adapt this code to XS/XCP, mostly playing with XenAPI version, but as
XCP is not taking precedence on Xen Source on many platforms, please keep
compatibility in mind.
