I am setting up a basic OpenStack Cloud using two virtual machines (Controller + Compute) as described in (this guide).

My topology is defined by the following diagram: ( (Topology))

Each node (Controller + Compute) requires both internet through a NAT and a direct internet access through a separate interface. To the best of my knowledge, I can only use the internet on a virtual machine through NAT. How do I get a direct internet access on a virtual machine? Which type of interface will I have to add for that?

You want a provider network. Documentation e.g. for Linuxbridge-based provider network; Openvswitch-based documentation is available as well, and the Install guide covers the subject, too.
