VirtualBox 是一款功能强大的 x86 虚拟机软件，它不仅具有丰富的特色，而且性能也很优异。更可喜的是，VirtualBox 于数日前走向开源，成为了一个发布在 GPL 许可之下的自由软件。VirtualBox 可以在 Linux 和 Windows 主机中运行，并支持在其中安装 Windows (NT 4.0、2000、XP、Server 2003、Vista)、DOS/Windows 3.x、Linux (2.4 和 2.6)、OpenBSD 等系列的客户操作系统。假如你曾经有用过虚拟机软件的经历的话，相信使用 VirtualBox 不在话下。即便你是一个新手，也没有关系。VirtualBox 提供了详细的文档，可以助你在短期内入门。
