Entrada del script
Este script lee un archivo de entrada que se describe en Archivo de entrada de los scripts PowerCLI de ejemplo para implementar escritorios Linux. Este script también solicita de manera interactiva la siguiente información:
- Dirección IP de vCenter Server
- Nombre de inicio de sesión de administrador para vCenter Server
- Contraseña de administrador para vCenter Server
- Tipo de clon, que solo puede ser completo
- Deshabilitar o no una consola de máquina virtual de vSphere

Ejecución del script
Los siguientes mensajes son de una ejecución del script:
PowerCLI C:\scripts> .\CloneVMs.ps1
Your vCenter address: 10.117.44.17
Your vCenter admin user name: administrator
Your vCenter admin user password: *******
Clone Type<"Full"> : Full
Disable vSphere VM Console ("yes" or "no", recommend "yes") : yes
El tiempo que tarde el proceso de clonación depende del número de máquinas de escritorio y puede variar de unos minutos a varias horas. Para verificar que el proceso se completó, acceda a vSphere Client y asegúrese de que la última máquina virtual de escritorio esté encendida, que tenga un nombre de host único y que VMware Tools se esté ejecutando.
