We don't want to expose the whole host filesystem, just selected
files, and we want to use our own configuration files (basically
that's what is in the skeleton part that we do ship).

Of course, if we can use virtio-9p, then excellent.  Is there good
documentation about virtio-9p?  What I can find is fragmentary or
based on reading qemu -help ...
