Mastering KVM Virtualization

Simply put, virtualization is the process of virtualizing something such as hardware, network, storage, application, access, and so on. Thus, virtualization can happen to any of the components.
Refer to the Advantages of virtualization section for more details on different possibilities in virtualization.
For example:
However, in the context of our book, we will discuss virtualization mainly in terms of software (hypervisor-based) virtualization. From this angle, virtualization is the process of hiding the underlying physical hardware so that it can be shared and used by multiple operating systems. This is also known as platform virtualization. In short, this action introduces a layer called a hypervisor/VMM between the underlying hardware and the operating systems running on top of it. The operating system running on top of the hypervisor is called the guest or virtual machine.
Let's discuss some of the advantages of virtualization:
As we discussed in the preceding section, even though virtualization can be achieved in different areas, I would like to talk more about operating system virtualization and software virtualization.
