What VirtualBox does
Oracle VirtualBox is a free, open-source type-2 hypervisor developed and maintained by Oracle. It enables you to run multiple operating systems simultaneously on a single physical machine by creating isolated virtual machines (VMs) that share the host's hardware resources without interfering with the host OS or each other. VirtualBox runs on Windows, macOS, and Linux hosts, and can host guest operating systems including various Linux distributions, Windows versions, and other x86-compatible operating systems. This cross-platform availability makes it a practical choice for developers, system administrators, and technical users who need to work across operating environments without maintaining separate physical hardware. The software provides snapshot functionality, which lets you capture the full state of a running virtual machine and revert to that captured state at any point. This is particularly useful for testing software changes, experimenting with system configurations, or running potentially risky operations with a straightforward rollback path. VirtualBox supports several virtual networking modes — including NAT, bridged, host-only, and internal networking — which gives you control over how guest machines communicate with the host, with each other, and with external networks. This flexibility suits use cases such as network testing, isolated development environments, and simulating multi-machine topologies on a single workstation. Guest Additions, a package installed inside the guest OS, improves the integration experience by enabling shared folders between host and guest, shared clipboard, drag-and-drop file transfer, and better display scaling. The base VirtualBox package is licensed under the GPL. A separate Extension Pack provides additional features and carries its own license terms.
