This is a collection of Packer templates, kickstart files, and shell scripts that can be used to build VirtualBox-backed Vagrant boxes from canonical Linux distribution ISOs.
$ git clone https://github.com/TFDuesing/packer-templates.git
$ cd packer-templates/<desired template directory>
$ packer build template.json
Once the build is complete, Packer will output a Vagrant .box file in the current working directory. You can add this box to your Vagrant installation with vagrant box add <name> </path/to/.box file>.
