TLDR
This tutorial series will detail as much as possible (without being massive) how is things working under the hood. It's always a good idea to remember how the evolution of virtualization came into the business. In virtualization, we have an Operational System (Bastion) that operates the hardware directly, and exposes the hardware to its virtual machines. This exposure enables these processes, virtual machines, to operate the hardware in different ways (bypassing instructions and so on), so virtual machines can do the work. This is done using a very ancient and rock-stable kernel feature called "namespaces"via the TL;DR App
