Inside the VM after everything is installed. For compression purpose.

• Zero out the vm and exit

sudo apt-get clean
sudo dd if=/dev/zero of=/EMPTY bs=1M
sudo rm -f /EMPTY
cat /dev/null > ~/.bash_history && history -c && exit

Outside the VM (after compressing and logging out)

• Creating the box
  • Make sure you have vagrant installed: https://www.vagrantup.com/downloads
  • Find the virtualbox VM name from the left panel of the VirtualBox main window.
  • OS specific (for making it easy to point to output directory)
    • Linux (Ubuntu):
      • Good practice to open a terminal to an appropriate directory
    • Windows:
      • Open powershell to an appropriate directory (ctrl + shift + right-mouse-click should give you option to open powershell as admin. Non-admin is also fine)
  • Use command (replace my-virtual-machine with the VM name and mynew with some useful name, say miniNDN):

vagrant package --base my-virtual-machine --output mynew.box

Post completion testing:

• Add the vagrant box to your box list (replace the mynewboxV1 name as desired, say miniNDNv1):

vagrant box add mynewboxV1 mynew.box

• Create a new Vagrantfile in a new directory (note: there's no extension) following miniNDN recommendations.

Vagrant.configure("2") do |config|
  config.vm.box = "mynewboxV1"
  config.vm.provider "virtualbox" do |vb|
    vb.memory = "8192"
    vb.cpus = "4"
  end
end

• Create the VM and bring it online

vagrant up

• Run any expected tests after logging in

vagrant ssh

• One example test to see if mininet is working

sudo mn --test pingall
