6. Virtualización en PowerShell (nivel intermedio) | Scripting and security

Table of Contents

La virtualización es un conjunto de técnicas hardware y/o software que permiten abstraer hardware y/o software creando la ilusión de que se están manejando dispositivos físicos, sistemas operativos, sesiones remotas de forma transparente al usuario.

Uno de los elementos principales de la virtualización es la máquina virtual que se está formada por recursos virtuales como una BIOS, memoria, procesador, disco duro, etc., y que se utilizan como si se tratase de recursos físicos.

Máquinas virtuales

Una máquina virtual está formada por una BIOS y un conjunto de recursos hardware (memoria, procesador, disco duro virtual, etc.) que se utilizan como si fuera la maquina física. Dentro de una maquina virtual se puede instalar cualquier sistema operativo, siempre y cuando el programa para virtualizar soporte ese sistema operativo. Desde las máquinas virtuales se puede imprimir, usar los dispositivos USB, navegar por la red, etc.

Microsoft dispone de herramientas para gestionar máquinas virtuales, una de ellas es Hyper-V.
