開源虛擬機，VirtualBox 5.0 beta 發布

VirtualBox 原先是德國一家軟件公司InnoTek所開發的虛擬系統軟件（已被SUN收購，而SUN已被Oracle收購），它不僅具有豐富的特色，而且性能 也很優異。VirtualBox 可以在 Linux 和 Windows 主機中運行，并支持在其中安裝 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軟件的經歷的話，相信使用 VirtualBox 不在話下。即便你是一個新手，也沒有關系。VirtualBox 提供了詳細的文檔，可以助你在短期內入門。

• Paravirtualization support for Windows and Linux guests to improve time-keeping accuracy and performance
