First, you can download VirtualBox from here. Make sure to select your operating system host in the downloads section. The VirtualBox wizard works like many other wizards. Select an installation location and click next through the installation.
UNLV Ubuntu image
A VirtualBox image of Ubuntu with pre-installed software can be found here. The default user is unlv and the password is password. By default, this image is set to use 4GB of memory, 8GB of secondary storage, and supports 2 CPUs. If this is too intensive, consider changing the settings. This is covered in the Settings section below, if you are unsure how to do this.
Included packages and software
- Python 3.5
- Google Chrome
Using the image
Installing an image with VirtualBox is realtively simple. After starting up VirtualBox, you should see a panel on the left that says "Tools". Click on "Tools". You should now see two buttons that say "Import" and "Export". To load an image, select import. Click on the folder icon, and then navigate to where you saved the image. After selecting the image, click next until VirtualBox begins to load the image. After it has loaded, you can use the image like any other OS you have installed.
Note: Older versions of VirtualBox lack the "Tools" section. The import option can also be accessed by File > Import
Installing a virtual OS
Here, we'll go over how to install an operating system.
After downloading a .iso image of the operating system you would like to install, open VirtualBox. You should see some buttons that say "New", "Settings", "Discard", and "Start". Click "New". You will be given several fields. Fill in the "name" with what you would like the OS to be displayed as. For the "Machine Folder", select "Other" via the dropdown.
Navigate to the location you have the .iso stored in. Select the type of installation and the OS name, if it exists. Click "Next". Decide on how much memory you would like to give the VM. For optimal performance, you should probably give it at least 2048 MB (2 GB). Click "Next". When you start the VM, now, you will be taken to the installation for whatever OS you are installing.
For a specific example, check out the Linux Guide Page, which has a short tutorial on specifically installing Ubuntu 16.
Running an OS
Simply select the OS from the list of operating systems on the left side of the Virtual Box windows, and select "Start". You can use the dropdown next to the start button to select what type of startup you would like.
- When closing out of a Virtual Machine, VirtualBox will ask you what you would like to do. You can choose to either suspend the VM, send a shutdown signal, or power off.
- Suspending the VM may take some time, however, the next time you start that VM it will pick up right from where you left off, with all programs, files, etc. still open. This can be useful if you need to open a lot of programs when you start up the VM.
- Sending a shutdown signal is equivalent to pressing the power button on a physical machine.
- Powering off is equivalent to holding down the power button on a physical machine.
