For KVM-based environments (which require nested virtualization support), update the README.md to note that VirtualBox is not supported. Also update the Vagrantfile for clearer indications that only VMware-based providers are supported.
Move Ansible provisioning to inside machines.each loop in the
`Vagrantfile`. Remove all support for VirtualBox (environment
requires nested virtualization support). Update README.md with
final steps and instructions. Remove unneeded `noop.yml` playbook.
This is an initial set of files for working with KVM and macvtap
interfaces for KVM guests. The environment is not yet functional,
but this is a start. Changes need to be made to the Ansible
provisioning, and a way to enable promiscuous mode needs to be found.
