What type of virtualization allows a guest OS to run on a client machine?

Client-side virtualization allows a guest operating system (OS) to run on a client machine, often referred to as a host machine. This type of virtualization is typically achieved through software applications known as hypervisors or virtual machine managers that enable the execution of multiple virtual machines, each with its own operating system, on the same physical hardware.

In this context, the client machine serves as the primary system where the virtualization software is installed, allowing users to create and manage virtual machines easily. This setup is particularly useful for developers and testers who need to run different operating systems for compatibility and testing purposes without requiring separate physical machines for each OS.

Server-side virtualization primarily focuses on virtualizing server resources and is often executed on powerful server hardware to optimize the utilization of resources across multiple servers. Host-based virtualization generally refers to the architecture where a hypervisor runs on top of the host operating system, which may not exclusively define the guest OS aspect within a client environment. Network virtualization deals with the abstraction of network resources, and it doesn't pertain to running guest operating systems directly on client machines. Thus, client-side virtualization is specifically tailored for running guest OS on a client machine.
