When it comes to installing and managing virtual machines, VirtualBox is one of the most popular choices for Linux users, particularly those running Ubuntu or Debian-based distributions.

VirtualBox is an open-source virtualization software that allows you to run multiple operating systems on a single machine.

With VirtualBox, you can create and manage virtual machines (VMs), which are self-contained environments that mimic the behavior of physical computers.

VirtualBox provides several benefits, including improved security, reduced hardware costs, and increased flexibility. For instance, you can use VirtualBox to test new software or operating systems without affecting your primary system, or to run legacy applications on newer versions of Ubuntu.
