A template Vagrantfile and associated Ansible playbook with some of my most commonly used configurations / directives.
You'll need VirtualBox, Vagrant, and Ansible installed to use this environment.
Additionally, the following plugin is useful to keep the VirtualBox Guest Additions in sync with the base box:
vagrant plugin install vagrant-vbguest
Fire up the Vagrant VM:
vagrant up
Ensure Ansible has run successfully and provisioned the boxes. If not, try again using vagrant provision
If you're having trouble with Vagrant, try enabling Vagrant's logging to see what's going on: export VAGRANT_LOG=info
