7.1.4 / 16-10-2024
VirtualBox
Accuracy
Performance
Features
VirtualBox is a powerful x86 and AMD/Intel64 virtualization solution for home and enterprise usage. It's quite feature rich, high performance yet is freely available as an Open Source Software. While it's mainly a community effort, Oracle is backing it to ensure it maintains high standards of quality.
Presently, it runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0+, DOS/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS/2, and OpenBSD.
