VirtualBox 發表 4.0.2

VirtualBox最早是德國一家軟件公司InnoTek所開發的虛擬系統軟件,後來被Sun收購,改名為Sun VirtualBox,在Sun被Oracle收購後現改名為Oracle VirtualBox。因為他是開放原始碼的,不同於VM,而且功能強大,可以在 Linux/Mac 和 Windows 主機中運行, 並支持在其中安裝 Windows (NT 4.0、2000、XP、Server 2003、Vista)、DOS/Windows 3.x、Linux (2.4 和 2.6)、OpenBSD 等系列的客戶操作系統.假如你曾經有用過虛擬機器軟體的經歷的話，相信使用 VirtualBox 輕鬆入手。即便你是一個新手，也沒有關係。VirtualBox 提供了詳細的說明文件，可以助你在短期內入門。
