Actually we ship only the supermin appliance, but you can build a real
appliance easily:

 $ guestfish -a /dev/null run
 $ ls -l /var/tmp/.guestfs-`id -un`/root

To see how libguestfs actually boots this, do:

 $ libguestfs-test-tool

and look carefully at the output, particularly the qemu command line.

Now that's the libguestfs appliance.  We also build "phony disk
images" for testing libguestfs.  These are quite useful because (a)
they are very small and (b) they look a lot like real operating
systems and (c) they have no licensing issues so you can redistribute
the binaries at will.  Downside is you can't boot them :-(

Currently during the libguestfs tests we build phony images of Debian,
Fedora, Ubuntu and Windows:

  $ du images/*.img
  14M	images/debian.img
  14M	images/fedora.img
  17M	images/ubuntu.img
  3.6M	images/windows.img

  -rw-rw-r--. 1 rjones rjones  83160 May  9 22:00 debian.img.xz
  -rw-rw-r--. 1 rjones rjones  84332 May  9 22:00 fedora.img.xz
  -rw-rw-r--. 1 rjones rjones  81760 May  9 22:00 ubuntu.img.xz
  -rw-rw-r--. 1 rjones rjones 263432 May  9 22:00 windows.img.xz

(They are sparse images so they all appear to be 512 MB in size in 'ls').

These might or might not be more useful for you.  You could also (more
practically TBH) distribute the build scripts for these images.  Take
a look in the images/ subdirectory of libguestfs source.
