Virtual machines are so common today. We can use them for different purposes, from a test facilities to the production environment. Main advantages are faster deployment, resistance to hardware failures and easier reverting to previous known good state.
Today we have wide choice of virtualization systems. We can choose virtualization software that needs regular operating system, like Windows or Linux, or a stand-alone virtualization solutions, that we can install on the bare metal chassis.
I will show you how to use Oracle Virtual Box version 5.x to build your own virtual lab. You can perform all those tasks on similar way in many other solutions. However, not all solutions can offer all options mentioned in this article.
We can speed up deployment and save precious resources in same time, if we’re using a virtual machine clones. Process is very easy. We should install bare operating system and all necessary drivers on machine with minimal requirements for a normal work. That’s all in first step.
Then we will use that virtual machine (VM) as a foundation for all other VMs. We’re saving time on new installation and basic configuration for every new machine. Therefore, this machine will be considered as template for all new similar VMs.
