I use Kubuntu 18.04 as my host operating system and VirtualBox as a hypervisor.
I have to mention that configuration may differ if you have other host and guest environments. So in this article, I explain how to do this in my case. In order to have this possibility, you need to configure network between your Host and Guest VM. For instance, you cannot ping it, access it through SSH, or if you develop a client-server application your client running on the host cannot server-side app running in the guest virtual machine. However, in this case you cannot get network access to your virtual machine from your host machine. Problemīy default, VirtualBox creates a NAT network interface for your new virtual machine to enable your guest VM to have access to the Internet. So I decided to write this post as a reminder for future myself on how to configure network for my testbed. Once I have done with my experiments, I delete this cloned VM in order to free disk space.Īs I do this initial configuration rarely, each time I have to search for instructions in the Internet how to configure network interfaces. When I need a new VM for my experiments, I clone this template VM, and I can almost instantly start my investigations. Then, I keep this virtual machine as a template.
In order to reach this goal, once a new version of the operating system appears (I prefer to use LTS versions of Ubuntu Server), I download its image and create a new virtual machine where I install the operating system from the downloaded image and make initial configuration. So as from time to time my experiments completely broke the system, I should have the possibility to deploy a clean testbed quickly. Therefore, in this article I will show how to configure VirtualBox and guest OSes so that you get access to your virtual machines from the host, e.g., through terminal. Unfortunately, by default after you have installed a guest virtual machine (VM) you do not have network access to it. Thus, to completely resemble my experience in the cloud I should have terminal access to the guest operating system. Usually, my guest operating system (OS) is Ubuntu Server because I usually use this OS in the cloud. In order to have the same environment and to keep my working machine clean from the garbage left after such experiments, I do my investigations in a virtualized environment. From time to time, I experiment with different tools.
