VirtualBox 是一款功能強(qiáng)大的 x86 虛擬機(jī)軟件，它不僅具有豐富的特色，而且性能也很優(yōu)異。更可喜的是，VirtualBox 于數(shù)日前走向開(kāi)源，成為了一個(gè)發(fā)布在 GPL 許可之下的自由軟件。
VirtualBox 原先是德國(guó)一家軟件公司InnoTek所開(kāi)發(fā)的虛擬系統(tǒng)軟件（已被SUN收購(gòu)，而SUN已被Oracle收購(gòu)），它不僅具有豐富的特色，而且性能 也很優(yōu)異。VirtualBox 可以在 Linux 和 Windows 主機(jī)中運(yùn)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(tǒng)。假如你曾經(jīng)有用過(guò)虛擬機(jī)軟件的經(jīng)歷的話，相信使用 VirtualBox 不在話下。即便你是一個(gè)新手，也沒(méi)有關(guān)系。VirtualBox 提供了詳細(xì)的文檔，可以助你在短期內(nèi)入門。
VirtualBox 3.2.6 版本是一個(gè)維護(hù)版本，主要修正bug的列表如下：
* 允許32位 Host 運(yùn)行 64位 SMP Guest，但不包括 Mac OS X 的 Host。(此特性需要 VT 支持)
* 修正了當(dāng)離開(kāi)全屏模式下 2D 視頻加速崩潰的情況。
* 為一個(gè)影響在 ext4/xfs 文件系統(tǒng)使用非同步 I/O 的內(nèi)核 bug 提供了一個(gè)解決方案。
* 能夠在 Arch Linux Guest 把 DRI 驅(qū)動(dòng)安裝到正確的位置上。
* 修正了64位 Windows Guest 的32位程序的 OpenGL 支持問(wèn)題。
* 為多個(gè) VRDP 遠(yuǎn)程連接增加了一個(gè) GUI 設(shè)置，對(duì)開(kāi)啟多屏輸出十分有用。
