开源虚拟机，VirtualBox 5.0 beta 发布

VirtualBox 原先是德国一家软件公司InnoTek所开发的虚拟系统软件（已被SUN收购，而SUN已被Oracle收购），它不仅具有丰富的特色，而且性能 也很优异。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。
