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>
