Introduction Virtual machines (VMs) are a powerful tool for creating and managing multiple operating systems on a single physical machine. They allow you to run different operating systems, applications, and services without the need for additional hardware. Instead of having multiple physical computers with their own dedicated resources, VMs share the resources of the host machine. Through this sharing of resources, VMs enable you to create isolated environments that can simulate different computing scenarios or test new software and applications without interfering with other processes. Setting up the Environment Installing KVM on the Host Machine Before deploying multiple virtual machines, ... Read More

Introduction HTML5 is the fifth and latest version of Hypertext Markup Language, which is the standard language used for creating web pages and applications.
