开源虚拟机VirtualBox v1.6.4发布

对于VMWare、VirtualPC这些虚拟机软件，可能大家都比较熟悉。VirtualBox是德国一家软件公司InnoTek所开发的虚拟系统软 件，它不仅具有丰富的特色，而且性能也很优异。更是开源的，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、Server2003、Vista)、DOS/Windows3.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。
