Bob Ball 5b9adb60de XenAPI: Move some boot-time functions to install-time
The boot-time script (prepare_guest.sh) is one of the less reliable parts
of the install process.  This change enables SSH into the host as well as
reporting of the IP address.  This significantly helps debugging issues
now and enables moving of all other setup code to being executed over SSH.

# It modifies the ubuntu image created by install_os_domU.sh
#
# This script is responsible for cusomtizing the fresh ubuntu
# image so on boot it runs the prepare_guest.sh script
# that modifies the VM so it is ready to run stack.sh.
# It does this by mounting the disk image of the VM.
#
# The resultant image is started by install_os_domU.sh,
# and once the VM has shutdown, build_xva.sh is run
