Persistent changes to machines in Eve-NG

When using Eve-NG, most x86-based virtualization happens via Qemu. You place a so-called base image in your Eve-NG machine and that image gets used by all of your nodes. Active nodes exist as a linked clone of the base image. I ran into the need to make some persistent changes to a base image. I did not want to set up another machine just to adjust my images so I figured out how to use my Eve-NG machine to do it. Read on to find out how.

Setting up the successor to UnetLab: EVE-NG!

I’m happy to bring an update to my previous article about Unetlab. The successor to Unetlab, named EVE-NG, is now released. EVE-NG stands for Emulated Virtual Environment Next Generation and it’s packed with cool new features. I will describe some of them in this article, along with the setup procedure which is very similar to setting up Unetlab.

Networking lab setup with UNetLab

UNetLab, short for Unified Networking Lab, is a Linux distribution that allows you to build your own networking labs. UNetLab can be seen as a hypervisor for images that are usually run on physical networking equipment or inside separate virtual machines. I wanted to incorporate setting up UNetLab in another article but decided to award the setup process with its own post.
