This is one way to fix the problem, and it's simple so we should
probably go with it, so ACK.

A more thorough fix would look at not just the first root returned
from libguestfs, but would look through all of the roots for the first
that has g.inspect_get_format(root) == "installed".

http://libguestfs.org/guestfs.3.html#guestfs_inspect_get_format

libguestfs is just being very thorough here by finding the installer
on the CD-ROM and returning it as an "installer" operating system.
