Mirantis Openstack has a bunch of Virtualbox Bash scripts for test/dev installation (NOT Vagrant)

https://software.mirantis.com/quick-start/

this is not such a crazy idea

personally, I would love an alternative to Vagrant i.e. Ansible driven dev

all it would take is a Virtualbox module written based on some of the other providers ..
