Steps to Deploy Virtual Machines in RHEV Environment

This article will guide you on how to #deploy #virtual #machines in the #RHEV environment and also on #Linux and #Windows virtual machines.

A Virtual Machine (#VM) is a compute resource that uses software instead of a physical computer to run programs and deploy apps. One or more virtual "guest" #machines run on a physical "host" machine.

The main purpose of VMs is to operate multiple operating systems at the same time, from the same piece of hardware. Without virtualization, operating multiple systems — like Windows and Linux — would require two separate physical units.

The two basic types of virtual machines are process and system VMs:

1. A process virtual machine allows you to run a single process as an application on a host machine. 

2. A system virtual machine is a fully virtualized #VM designed to be a substitute for a physical machine.

Your virtual machine internet connection goes through your computer and through your router. So they can track your router's #IP address, and possibly track you down at least to your city, if not to individual street or house.
