![]() 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.
