開源虛擬機的VirtualBox團隊于本周四正式釋放出了第三個VirtualBox 5.0測試版本。
VirtualBox 4.0的后一個主要版本在2010年12月發布，它采用了新的圖形化用戶界面，新的虛擬化硬件和重組的項目設計，進行了重大的改版。但項目主要版本的發布步伐緩慢，上一次重要版本（版本4.3）在2013年底才發布。從那時起，一切都被正式稱為“維護”發布。
時隔五年之后的今年四月，VirtualBox，由Sun公司創建，現在由甲骨文管理的開源虛擬化系統，獲得了近5年來次的主版本更新發布，還是有新的東西加入：Windows/Linux等客戶虛擬機支持PV、XHCI控制器支持USB 3.0設備、雙向復制和粘貼。
在VirtualBox 5.0 Beta 3中也帶來了很多Bug修復，客戶機可獲得XSAVE/AVX/AVX2等擴展、改進GUI加密、改進音量控制、修復SB16播放等改進。
