The Complete Practical Docker Guide - Virtual Machines Architecture

The video tutorial explains the architecture and use of virtual machines. It covers the requirements for creating virtual machines, including the need for a physical or virtual server and a host operating system. The tutorial discusses hypervisors like VirtualBox and VMware Fusion, and how they allow for the creation of virtual machines with different guest operating systems. It highlights the isolation and resource allocation of virtual machines, emphasizing their ability to run separate applications independently. The instructor also demonstrates personal use of virtual machines on a Mac computer using VMware Fusion, showcasing the running of multiple virtual machines with different operating systems.
