fix to save .vmdk files
initial stab at a Vagrantfile
import qcow2box.sh

copied from
https://github.com/SUSE/cloud/blob/master/dev-setup/wip-vagrant/scripts/generate-box.sh

In general I *hate* copying code around, but in this case the repository
needs to be self-contained.  Hopefully Thomas or I can turn this script
into a proper independent github project at some point.
don't hardcode Vagrantfile and metadata.json within script
fix ANSI colour sequences
improve variable naming and fix relative paths for input
clarify that actions are in progress
noone uses 2-column indent for shell ;-)

not even most crazy Rubyists ;-)
ensure run as root
use first partition of .qcow2
don't bother unloading nbd - something else might be using it too
wrap code in functions for clarity
set up sudoers
disable UseDNS in sshd
tweak LESS
switch default provider to virtualbox
change vdisk size to 16GB
add OVF file for admin appliance

This was generated manually in VirtualBox and then exported as OVF.
