INSTALL LLIUREX ON A VIRTUAL MACHINE
A Virtual Machine is a program which simulates (actually the correct verb to use in this context is "to emulate") a computer. In this exercice we are going to create a virtual machine and to install the LLiurex 15.05 operative system on it. In this way in your real computer (the host computer) you will have running a fully working guess virtual computer in which you will be the admin user. Keep in mind that you are a simple ·"user" with no administrative privileges, and this means that Lliurex won't allow you to perform any action that might damage your computer, but some of these actions form part of this subject and must be practiced in the classroom.
In the following picture you can see how a virtual machine looks like. It is a LLiurex running on a host computer window.
- Use the file browser Nautilus (menu Lugares->carpeta personal) to check out if there is a file called lliurex-escriptori_amd64_1505_latest.iso inside the \home\publico\ folder. This is the ISO LLiurex 15.05 install file, in it's desktop version.
- Run Oracle Virtual box, selecting the menu Aplicaciones->Administración LLiurex->Oracle VirtualBox menu. VirtualBox is the program we will use to create and manage our virtual machines.
- Create a new virtual machine clicking on the button nuevo
- Write a name for the new virtual machine, ( see the picture below, but don't name it LLiurex 14, name it LLiurex 15 instead). Write the type of operative system -linux, and the subtype Ubuntu 64 bits as well. Then click on the next buttton
In this window select 2Gb of memory for the virtual machine. Remember 1GB equals 1024 Mb
The virtual machine, the operative system you will install on it, and the programs and data must be saved in a virtual hard disk. Actually this is a file in which Virtualbox emulates a hard disk. Chose the optino to create a new virtual disk
- Select hard disk type vdi
- Select dynamic reservation as well. This option means that even if the virtual hard disk is set to a 20GB size, the vdi file will take up just around 6Gb at the beginning (the size of the operative system), and will go growing according you need more space for programs and data to a maximum of 20Gb size
- Finally, write a name for the vdi file, and set its maximum size to around 20gb, then clic on crear
- Now the virtual machine has been created. You have a virtual computer ready to be turned on, and be displayed in a window. The virtual machine name must apear on the left panel, For the time beeing, your computer has no opertative system. You must install LLiurex 15 on it in the following steps
- Select the VM (virtual machine) in the pannel on the left as shown in the picture. The right pannel will show a report of the different hardware components of your VM.
- We are going to change the amount of memory in the host system reserved for video in the VM. The default option is que en este momento es clearly insufficiente (just 12 Mb). Make a doble click on the pantalla section.
- Select a size of 128Mb and enable 3D acceleration
- Our VM is useless, unless we install the operative system. If we turn it on (clicking on the button iniciar) it will show a message asking you to insert a boot DVD disk. Otherwise the computer won't boot (won't turn on). If we had the LLiurex install DVD we could install LLiurex now, but we don't have it. We have an ISO install file instead.
- An ISO file is a file wich contais an image of a DVD. This means that all the file contents have been dumped into the file, turning it into a perfect copy of the DVD. We must mount the \home\publico\lliurex-escriptori_amd64_1505_latest.iso (the LLiurex ISO) as it was a real DVD and install the Operative System. Select the almacenamiento section
- Click on the DVD icon (in the place signaled by the red arrow in the image below), and then
- Click on the icon signaled by the blue arrow in the image above to deploy the menu showed in the image below. Select seleccionar un archivo de disco virtual de CD/DVD. Select the file \home\publico\lliurex-escriptori_amd64_1505_latest.iso
- Click again on the button iniciar to turn on the VM. This time the VM boots using the Iso install file an the installation of LLiurex starsts
- Select a language (spanish, english or Valencian) and click on the button instala lliurex.
- Make sure that the following window showes that all the LLiurex installation requirements are met Enable the option Descargar actualizaciones y software de terceros
- In our VM there's nothing installed, so you can delete all the contents in the hard disk and install Lliurex using all the space available. So select esborra el disk i .....
- Finally select instalar ahora
- Select Madrid date and time
- Select the keyboad set up showed in the following picture
- In the following screen enter your name, the computer name and the username of the admin username.
- Restart the VM when the installation process ends. A window will pop up showing that the boot disk (the ISO file) is still mounted and must be removed before start the system. Return to the VirtualBox main window, select the Almacenamiento section and remove the Iso file form the unit D:
- Take a screen picture showing the VM running in a window in your desktop and upload it to moodle, tho the link Upload the screen capture of your Virtual Machine first boot.
