Jack Wallen walks you through the process of creating virtual networks with VirtualBox so you can test guest servers and desktops without affecting your company network. In short, we have assigned separate network interfaces for Management Network and for Internet access for the OpenStack nodes (VirtualBox VMs).How to create VirtualBox networks with the Host Network Manager But the VM instances also need Internet access. So I recommend an additional interface of type NAT_ _just to accomplish that.So host-only network is the best option for eth0. And with NAT you will need Port forwarding to be configured to access Horizon/SSH on the VM. If your laptop was without network connectivity, bridge adapter will not work. We could have used either a bridge adapter or NAT. But both approaches have drawbacks.This ensures that all virtual machines on that ‘Host-only’ network and the host laptop are able to talk to each other. In the settings above, the eth0 is realized using VirtualBox ‘Host-only’ adapter.Typically, it is also used to access the Horizon GUI or to execute CLI via SSH. The eth0 interface on the OpenStack nodes is used for API requests and responses.The additional interface is very useful if you are running your virtual box instances on a laptop.

Without this setting packets will not reach from OpenStack tenant VMs (that will be started inside the compute node), to the OpenStack controller. Tip: it is important to enable Promiscuous mode on eth1, the data traffic interfaces on both compute and controller node. VirtualBox Settings for Controller Node VirtualBox Network settings for Compute Node 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.
