Is there any reason for qemu to know the file name if libvirt wants it
to use only pre-opened fds anyway? I don't think it should even know the
file name.
In this case we shouldn't write backing file filenames into image files,
but some sort of libvirt token...... then again that will be a lot of
fun if you want to run things on the command line afterwards.
