instalacion
1. En primer lugar, evidentemente, tendremos que hacer acopio de las herramientas necesarias para el tutorial. Estas son la propia aplicación de VirtualBox que podemos descargar desde aquí, y una imagen ISO o de un formato similar del sistema operativo que queremos instalar.
2. Una vez descargado el instalador de VirtualBox lo ejecutaremos y pasaremos por los 7 pasos que tiene el proceso de instalación. Es importante dejar todas las opciones por defecto si no estamos muy seguros de lo que estamos haciendo. Cabe destacar también que en un momento dado de la instalación el proceso se detendrá y mostrará un aviso como el siguiente, en el que marcaremos la casilla de Siempre confiar en el software de “Oracle Corporation” y pulsaremos sobre Instalar.
Creando una máquina virtual
1. Tras terminar el proceso de instalación de VirtualBox pasaremos a crear nuestra primera máquina virtual, para ello, una vez abierto el programa, pulsaremos sobre el botón Nueva en la esquina superior izquierda. Introduciremos un nombre a la máquina y especificaremos qué tipo de sistema operativo instalaremos tal y como mostramos en la imagen siguiente.
2. A continuación, en la siguiente pantalla que se nos muestra seleccionaremos la cantidad de memoria RAM que destinaremos a la máquina virtual. El valor de esta depende de varios factores como por ejemplo la cantidad de memoria disponible en nuestro equipo y la cantidad de memoria que requiera el sistema operativo que vayamos a instalar. En nuestro caso disponemos de 8 GB de memoria RAM, y al poner Ubuntu como sistema operativo le destinaremos 2 GB para ir sobrados.
Debemos tener cuidado con este valor, pues si nos pasamos de un cierto margen vamos a provocar que tanto la máquina virtual como el sistema operativo sobre el que corre VirtualBox vaya extremadamente lento. Para ello, y a grandes rasgos, no debemos asignarle a la máquina virtual más del 45% de la memoria RAM disponible. En caso de desconocer la RAM disponible lo podremos hacer yendo a Inicio > Click derecho sobre Equipo > Propiedades, allí, en la pestaña Sistema aparece el parámetro Memoria Instalada (RAM).
3. En el siguiente paso se nos pedirá sobre el disco duro. Si tenemos que instalar un sistema operativo, es decir, que nadie nos ha pasado su disco duro virtual, y necesitamos que nuestro equipo tenga disco duro (la mayoría de los casos) dejaremos marcada la opción Crear un disco duro virtual ahora.
4. En este paso se nos pide el formato que le queremos dar a la unidad de disco duro virtual. En general dejaremos la opción predeterminada, es decir, VDI (VirtualBox Disk Image). En caso de querer usar ese disco duro en otro software de virtualización ya seleccionaremos la opción que mas nos convenga.
5. A continuación se nos pedirá si queremos que tenga tamaño variable o fijo. Personalmente recomiendo un disco de tamaño variable o dinámico, pero esta opción depende del uso que le vayamos a dar a la máquina.
6. Para finalizar con la creación de la máquina, le asignaremos al disco duro virtual un nombre y un tamaño inicial, por lo general podemos dejar ambos valores como predeterminados, pero en caso de querer variar el tamaño del disco es recomendable siempre poner uno de mayor tamaño que de menor.
installation
1. First, obviously, we will have to collect the necessary tools for the tutorial. These are the VirtualBox application itself that we can download from here, and an ISO image or a similar format of the operating system that we want to install.
2. Once the VirtualBox installer is downloaded, we will execute it and go through the 7 steps of the installation process. It is important to leave all options by default if we are not sure what we are doing. It should also be noted that at a given moment in the installation the process will stop and display a warning like the following one, in which we will check the Always trust the "Oracle Corporation" software box and click on Install.

Creating a virtual machine
New virtual machine
1. After finishing the VirtualBox installation process we will create our first virtual machine, for this, once the program is opened, click on the New button in the upper left corner. We will introduce a name to the machine and specify what type of operating system we will install as shown in the following image.
2. Next, in the next screen shown we will select the amount of RAM that we will allocate to the virtual machine. The value of this depends on several factors such as the amount of memory available on our computer and the amount of memory required by the operating system that we are going to install. In our case we have 8 GB of RAM, and when we put Ubuntu as an operating system, we will allocate 2 GB to be left over.
RAM allocation for the virtual machine
We must be careful with this value, because if we go from a certain margin we will cause both the virtual machine and the operating system on which VirtualBox runs to go extremely slow. To do this, and broadly speaking, we should not allocate more than 45% of the available RAM to the virtual machine. In case of not knowing the available RAM we can do it by going to Start> Right click on Equipment> Properties, there, in the System tab the parameter Installed Memory (RAM) appears.
3. In the next step we will be asked about the hard drive. If we have to install an operating system, that is, no one has passed us their virtual hard disk, and we need our team to have a hard disk (in most cases) we will leave the option Create a virtual hard disk now.
4. In this step we are asked the format that we want to give the virtual hard disk drive. In general we will leave the default option, that is, VDI (VirtualBox Disk Image). If you want to use that hard disk in other virtualization software, we will select the option that suits us.
5. Next we will be asked if we want it to have a variable or fixed size. Personally I recommend a disk of variable or dynamic size, but this option depends on the use that we will give to the machine.
6. To finish with the creation of the machine, we will assign the virtual hard disk an initial name and size, usually we can leave both values as defaults, but if you want to vary the size of the disk it is always advisable to put one of larger than smaller.
