This is a tutorial to rebuild Teams/Cloud/VagrantBaseBoxes yourself.


Installing Packer

Packer is a tool for creating identical machine images for multiple platforms from a single source configuration. Packer is written in Go.

On Stretch:

sudo apt install packer virtualbox

NOTE: virtualbox is in contrib because the emulator part requires a BIOS that can only be compiled with a non-free compiler. However we're using here only to test the Vagrant box, it is not required for building the box.

Installing import2vox

You need the latest version of, installed in your path (direct link to the file)

Rebuild the vanilla Debian base boxes

Checkout the debian-vm-templates git repo:

git clone

Validate a template before building

cd debian-vm-templates/packer-virtualbox-vagrant
packer validate jessie64.json

Rebuild the box. This will start a VirtualBox virtual machine, in which a preseeded debian installer will run:

packer build jessie64.json

This produces only a RAW Qemu image, however. To produce a BOX file as expected by Vagrant, you should probably use the wrapper scripts provided in the Makefile, which also test the box:

#build a Jessie base box, and test it is working as expected
make jessie.tested

The resulting box will be in

If you see the following error when trying to build a basebox:

ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy

It's most likely because VirtualBox is still running a VM. You may need to shutdown (vagrant halt) all running VMs to complete the build.
