Vagrant providers each require a custom provider-specific box format.
This folder shows the example contents of a box for the libvirt provider.
To turn this into a box create a Vagrant image according documentation (don't
forget to install rsync command) and create box with following command:
$ tar cvzf custom_box.box ./metadata.json ./Vagrantfile ./box.img
This box works by using Vagrant's built-in Vagrantfile merging to setup defaults for Libvirt. These defaults can easily be overwritten by higher-level Vagrantfiles (such as project root Vagrantfiles).
Libvirt box should define at least three data fields in metadata.json file.
- provider - Provider name is libvirt.
- format - Currently supported format is qcow2.
- virtual_size - Virtual size of image in GBytes.
Instead of creating a box from scratch, you can use vagrant-mutate to take boxes created for other Vagrant providers and use them with vagrant-libvirt.
