VirtualBox概况 对于 VMWare、Virtual PC 这些虚拟机软件，可能大家都比较熟悉。VirtualBox也是一款虚拟机软件。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。
