Key Takeaways

Virtual Machines – Base Unit of VMware Virtualization

A virtual machine (VM) is the fundamental building block of VMware virtualization. A visitor operating system is a software-based simulation of a physical computer running in a virtual machine.

VMware offers a variety of file management utilities, including vSphere Client. This command-line interface for virtual machine administration enables the configuration of virtual machine parameters. 

Users can choose from two types of Virtual machines—process VMs and system VMs:  

1. Process Virtual Machine

Provides a platform-independent development environment by masking the hardware or operating system details, allowing a single process to act as an application on a host machine.

Example: Java Virtual Machine allowing Java programs to run on any OS.

2. System Virtual Machine

Completely virtualizes to replace a physical machine. A system platform enables sharing of material resources of a host computer among multiple virtual machines, each of which runs its copy of the operating system.

Example: Utilizes a hypervisor, which can operate on isolated hardware, such as VMware ESXi, or on top of an operating system.
