VirtualBox最早是德国一家软件公司InnoTek所开发的虚拟系统软件，后来被Sun收购，改名为Sun VirtualBox，在Sun被Oracle收购后现改名为Oracle VirtualBox。因为他是开源的，不同于VM，而且功能强大，可以在Linux/Mac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 本文来源gaodai#ma#com搞*!代#%^码$网*提供了详细的文档，可以助你在短期内入门。
