I'm not a maintainer of libxl myself, but my first suggestion would be
to store this information inside of xenstore. There's already a "/libxl"
directory used in order to stash some toolstack specific info, adding a
new directory/hierarchy there to store the local attachments seems like
the best option IMHO.
