5. Setting Up the Virtualization Environment (VirtualBox)

Linux Basics: From Zero to CLI Hero

Installing and Configuring VirtualBox

Before downloading the Ubuntu ISO, ensure VirtualBox is installed and configured.

Steps for Installation:

  1. Download VirtualBox from the official Oracle website.
  2. Install it using the default settings.
  3. Crucial Host Setting: Ensure Hardware Virtualization (VT-x on Intel, AMD-V on AMD) is enabled in your computer's BIOS/UEFI settings. Without this, the VM will run extremely slowly or fail to launch.

Creating the New Virtual Machine

  1. Open VirtualBox and click 'New'.
  2. Name: Ubuntu-Linux-Course
  3. Type: Linux
  4. Version: Ubuntu (64-bit)
  5. Memory (RAM): Allocate at least 4GB (4096 MB) if your host has 8GB or more. Never allocate more than half of your host RAM.
  6. Hard Disk: Select 'Create a virtual hard disk now'.
  7. Disk Type: VDI (VirtualBox Disk Image).
  8. Allocation: Choose Dynamically allocated (saves space on your host drive).
  9. Size: Set the virtual disk size to at least 40 GB.
