VirtualBox is a free and open-source Type 2 (Hosted) hypervisor developed by Oracle Corporation.
It allows users to create and run multiple virtual machines (VMs) on a single physical computer.
👉 VirtualBox lets you run another operating system inside your current operating system.
Example:
Now Ubuntu runs inside Windows as a virtual machine.
Architecture:
Physical Hardware → Host OS → VirtualBox → Virtual Machines
Since it runs on top of a host OS, it is called a Type 2 Hypervisor (Hosted Hypervisor).
VirtualBox can be installed on:
✔ Create multiple virtual machines
✔ Snapshot support
✔ Shared folders
✔ USB device support
✔ Virtual networking (NAT, Bridged, Host-only)
✔ Guest Additions for better performance
