ocaml-libvirt/0001-Add-a-binding-for-virDomainCreateXML.patch

From 7483c7454538584a3dbe4582096f058e6e877df6 Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>
Date: Fri, 6 Mar 2015 15:35:46 +0000
Subject: [PATCH] Add a binding for virDomainCreateXML.

This is more modern than the ancient virDomainCreateLinux API,
and crucially allows you to pass flags such as AUTODESTROY.
