免费开源虚拟机:VirtualBox 4.3.2正式版下载

VirtualBox虚拟机三大特点:免费、小巧、多国语言(含中文)。VirtualBox可以跨平台运行操作,支持安装Windows (NT 4.0、2000、XP、Server 2003、Vista、Win7、Win8、Win8.1等)、DOS/Windows 3.x、Linux、OpenBSD等系列的客户操作系统。

上个月VirtualBox发布稳定版VirtualBox 4.3.0,修复了在Win8.1下引起了异常的睡眠和休眠问题,这个月又迎来了新版VirtualBox 4.3.2的小幅升级,依旧是对性能和bug的修复和完善。

VirtualBox 4.3.2更新日记:

• VMM: fixed detection of VT-x on certain machines where the BIOS would not set the VMX LOCK feature bit, which affected the VM settings in the GUI
