The work consists of three parts: * Allow for bootstrapping remotely, this makes it possible to run the tests on e.g. OSX with VirtualBox installed * Make bootstrapping a fully automated process where the manifests can be generated by the tests and the tests can call the bootstrapper directly in python * Create a framework wherein instances can be booted up using the bootstrapped images and subsequently tested
