Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

Peter Krempa 3ad5186ed3 virsh: Remove <backingStore> when changing cdrom media source
Since the code is changing the source image path by modifying the
existing XML snippet the <backingStore> stays in place.

As <backingStore> is relevant to the <source> part of the image, the
update of that part makes the element invalid.

CD/floppy images usually don't have a backing chain and the element is
currently ignored though but it might start being used in the future so
let's start behaving correctly.

Drop the <backingStore> subtree once we want to update the XML.

Before this patch, you'd get:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
      <driver name="qemu" type="qcow2"/>

      <backingStore type="file" index="1">
        <format type="qcow2"/>
        <source file="/var/lib/libvirt/images/vm.1436949097"/>
        <backingStore/>
      </backingStore>
      <target dev="hdc" bus="ide"/>
      ...
    </disk>

After:

 $ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
      <driver name="qemu" type="qcow2"/>

      <target dev="hdc" bus="ide"/>
      ...
    </disk>

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
