I'm investigating Ansible for server and application provisioning. My application is currently provisioned with shell scripts in Vagrant. Rather than rewrite my scripts I've taken a sample and attempted to deploy it.

It appears to deploy fine, but I've seeing a failure message after what looks like a series of successful steps:

» vagrant provision                                       ~/vm/blvagrant 1 ?
[default] Running provisioner: ansible...

Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.

How do I go about getting additional debug information? I've already added ansible.verbose = true to my vagrant config which results in the dictionaries being displayed within the output above.
