第 1 章 Basic concepts of virtualization in RHEL


If you are unfamiliar with the concept of virtualization or its implementation in Linux, the following sections provide a general overview of virtualization in RHEL 10: its basics, advantages, components, and other possible virtualization solutions provided by Red Hat.

1.1. What is virtualization?

RHEL 10 provides the virtualization functionality, which enables a machine running RHEL 10 to host multiple virtual machines (VMs), also referred to as guests. VMs use the host’s physical hardware and computing resources to run a separate, virtualized operating system (guest OS) as a user-space process on the host’s operating system.

That is, virtualization makes it possible to have operating systems within operating systems.

VMs enable you to safely test software configurations and features, run legacy software, or optimize the workload efficiency of your hardware. For more information about the benefits, see Advantages of virtualization.
