lo is a loopback interface, while enp0s3 and enp0s8 corresponds to the NAT and Host-only networks correspondingly. In my case, these are lo, enp0s3 and enp0s8. Most probably, you would spot three network interfaces. Ubuntu 16.04ДЇirst of all, you need to check what network interfaces are available using the following command: $ ifconfig -a

If they are the same, generate new random MAC address.ДЇurther, I will show how to configure network in Ubuntu 16.04 and 18.04, in particular, how to set (or change if you run several VMs) static IP address. Moreover, make sure that all MAC addresses are different in the вЂњAdvancedвЂќ settings of Network adapters (see Figure 1). You can set hostname running the command in the guest machine: $ sudo hostname newname If you plan to have several clones of machines running simultaneously, make sure that all of them would have different IP addresses, hostnames, and all their adapters have different MAC addresses. By default, VirtualBox activates one adapter that is attached to NAT. VirtualBox ConfigurationДЄfter you have installed Ubuntu Server, shut down your virtual machine, open its вЂњSettingsвЂќ (select from the menu Machine -> Settings, or press Ctrl+S), and check вЂњNetworkвЂќ configuration. Here, I show how to configure Ubuntu Server 16.04 and Ubuntu Server 18.04 (two most popular LTS versions of Ubuntu Server now), so as the process is different for them. 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. ProblemД«y 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.ДЄs 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.
