VirtualBox – 免費輕量級的開源虛擬機軟件！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收購後改名為Oracle VM VirtualBox），它不僅具有豐富的特性，而且性能也很優異。可以在Linux和Windows主機中運行，並支持在其中安裝Windows（NT 4.0,2000，XP，Server 2003，Vista，Win7，Win8，Win10，Win2012，Windows Server 2016），DOS / Windows 3.x，Linux（2.4和2.6），OpenBSD等系列的客戶操作系統。非常適合新手入門！

Oracle VirtualBox 5.2.22已經正式發布，此次版本更新中對各種視頻驅動程序進行了更新/修復，並針對Linux Kernel 4.19進行了各種更新。

Virtualbox 5.2.22更新主要包括

VirtualBox是甲骨文（Oracle）公司推出的跨平台開源虛擬化軟件，支持GNU / Linux，Windows，macOS和Solaris等各種系統。今天，公司突然宣布了VirtualBox 5.2正式版，基於近期上線的Qt5技術帶來更現代化的通用用戶界面，此外新增了諸多實用功能來輔助虛擬化任務。其中最值得關注的新功能就是能夠完整導出和存儲虛擬主機至雲端。

在新版本中，甲骨文允許用戶導出虛擬主機至Oracle Cloud（OPC）公共，允許用戶在多個VirtualBox安裝實例上輕鬆部署虛擬主機。用戶不再需要將虛擬主機導出到移動硬盤上，再遷移到其他電腦上，只需要從Oracle Cloud下載就能輕鬆完成。
