Virtual machines
A virtual machine is a software implementation of a machine such as your physical hardware that executes programs like a physical machine. It runs its own operating system and allows you to host your application on it. Like physical hardware, the virtual machine uses virtual devices such as virtual hard drives, CPUs, network adapters, memory, and other hardware resources that are managed by a virtualization layer, in our case, KVM. KVM translates all these virtual resource requests to the physical hardware where the virtual machine is hosted.
Creating Linux virtual machines
On RHEV, you can create a virtual machine from existing virtual machine templates or from scratch. Since this is our fresh deployment, we are going to learn how to create a virtual machine from scratch, and then in later sections of the chapter, we are going to learn how to create a virtual machine template and clone a virtual machine using these templates.
