Oracle VM VirtualBox is a powerful, free, open-source virtualization software that enables you to run multiple operating systems simultaneously on a single computer. Whether you need to test software, run legacy applications, or explore different operating systems, VirtualBox provides enterprise-grade virtualization without cost.
VirtualBox supports a wide range of guest operating systems including Windows (from 3.1 to 11), Linux distributions, macOS (on Mac hardware), BSD variants, Solaris, and more. Each virtual machine runs in its own window with configurable resources including CPU cores, memory, storage, and network adapters.
The snapshot feature captures the exact state of a virtual machine at any point, allowing you to experiment freely and roll back changes instantly. Snapshot branching enables exploring multiple paths from a single point. Clone functionality creates exact copies of virtual machines for testing variations.
Shared folders enable seamless file exchange between host and guest operating systems. The shared clipboard transfers text and images bidirectionally. Drag and drop support moves files directly between host and guest.
Guest Additions enhance integration with better video drivers, mouse pointer integration, time synchronization, and seamless windows mode that displays guest applications directly on the host desktop. USB passthrough provides direct device access to guest systems.
VirtualBox includes a command-line interface for scripting and automation. Network options include NAT, bridged, internal, and host-only networking. The virtual network editor creates complex network topologies for testing.
