Jiri Denemark a2e369bc00 conf: Output disk backing store details in domain XML 
The XML for quite a longish backing chain is shown below:

  <disk type='network' device='disk'>
    <driver name='qemu' type='qcow2'/>
    <source protocol='nbd' name='bar'>
      <host transport='unix' socket='/var/run/nbdsock'/>
    </source>
    <backingStore type='block' index='1'>
      <format type='qcow2'/>
      <source dev='/dev/HostVG/QEMUGuest1'/>
      <backingStore type='file' index='2'>
        <format type='qcow2'/>
        <source file='/tmp/image2.qcow'/>
        <backingStore type='file' index='3'>
          <format type='qcow2'/>
          <source file='/tmp/image3.qcow'/>
          <backingStore type='file' index='4'>
            <format type='qcow2'/>
            <source file='/tmp/image4.qcow'/>
            <backingStore type='file' index='5'>
              <format type='qcow2'/>
              <source file='/tmp/image5.qcow'/>
              <backingStore type='file' index='6'>
                <format type='raw'/>
                <source file='/tmp/Fedora-17-x86_64-Live-KDE.iso'/>
                <backingStore/>
              </backingStore>
            </backingStore>
          </backingStore>
        </backingStore>
      </backingStore>
    </backingStore>
    <target dev='vdb' bus='virtio'/>
  </disk>

Various disk types and formats can be mixed in one chain. The
<backingStore/> empty element marks the end of the backing chain and it
is there mostly for future support of parsing the chain provided by a
user. If it's missing, we are supposed to probe for the rest of the
chain ourselves, otherwise complete chain was provided by the user. The
index attributes of backingStore elements can be used to unambiguously
identify a specific part of the image chain.
