VirtualBox Network settings for Controller Node The tables below shows how each interface or adapter needs to be configured on Virtual Box. And shortly I will explain why the additional interface is useful. But since we are going to run these as virtual box instances, I recommend an additional interface. The physical connectivity between the two nodes should be as follows:Īs you can see you need at least three network interfaces on the controller node and two on the compute node. We will also assume that VM instances require External network (Internet) access. We will consider a two-node OpenStack setup with one node acting as API Server and Network Node (generally called Controller) and the second node acting as Compute node. Another reason is that a multi-node installation is what real users of OpenStack will also be deploying. This is important for me because much of my work related to OpenStack revolves around Networking. While most people use DevStack to accomplish this I prefer to setup a multi-node installation. This blog will not cover the steps to install and create a virtual machine using VirtualBox. I will also share some tips that are important in this deployment. I will be focusing only on the networking aspects when using VirtualBox. In this blog, I will share the details of the VirtualBox based multi-node OpenStack installation. The best way to learn OpenStack is by installing, running and playing with it directly.
