摘要： Apparatuses, methods and storage media associated with switching operating systems are disclosed herewith. In embodiments, an apparatus for computing may include one or more processors; and a virtual machine manager to be operated by the one or more processors to instantiate a first virtual machine with a first operating system in a background, and a second virtual machine with a second operating system in a foreground; wherein the virtual machine manager is further to place the first virtual machine, on instantiation, in background into a standby state. Other embodiments may be disclosed or claimed.

摘要： Technologies for transitioning between operating systems include a computing device having a main memory and a data storage device. The computing device executes a first operating system and monitors for an operating system toggle event. The toggle event may be a software command, a hardware buttonpress, or other user command. In response to the toggle event, the computing device copies state data of the first operating system to a reserved memory area. After copying the state data, the computing device executes a second operating system. While the second operating system is executing, the computing device copies the state data of the first operating system from the reserved memory area to the data storage device. The computing device monitors for operating system toggle events during execution of the second operating system and may similarly toggle execution back to the first operating system. Other embodiments are described and claimed.
摘要翻译：用于在操作系统之间转换的技术包括具有主存储器和数据存储设备的计算设备。计算设备执行第一操作系统并监视操作系统切换事件。切换事件可以是软件命令，硬件按钮或其他用户命令。响应于切换事件，计算设备将第一操作系统的状态数据复制到保留的存储器区域。在复制状态数据之后，计算设备执行第二操作系统。当第二操作系统正在执行时，计算设备将第一操作系统的状态数据从保留的存储区域复制到数据存储设备。计算设备在执行第二操作系统期间监视操作系统切换事件，并且可以类似地将执行切换回第一操作系统。描述和要求保护其他实施例。

摘要： The present application is directed to access isolation for multi-operating system devices. In general, a device may be configured using firmware to accommodate more than one operating system (OS) operating concurrently on the device or to transition from one OS to another. An access isolation module (AIM) in the firmware may determine a device equipment configuration and may partition the equipment for use by multiple operating systems. The AIM may disable OS-based equipment sensing and may allocate at least a portion of the equipment to each OS using customized tables. When transitioning between operating systems, the AIM may help to ensure that information from one OS is not accessible to others. For example, the AIM may detect when a foreground OS is to be replaced by a background OS, and may protect (e.g., lockout or encrypt) the files of the foreground OS prior to the background OS becoming active.
摘要翻译：本应用针对多操作系统设备的访问隔离。通常，可以使用固件来配置设备以容纳在设备上同时运行的多个操作系统（OS）或者从一个OS转换到另一个操作系统。固件中的访问隔离模块（AIM）可以确定设备设备配置，并且可以划分设备以供多个操作系统使用。 AIM可以禁用基于操作系统的设备感测，并且可以使用定制的表将至少一部分设备分配给每个OS。当在操作系统之间转换时，AIM可以帮助确保来自一个操作系统的信息不被其他人访问。例如，AIM可以检测前景OS何时被后台OS替换，并且可以在背景OS变为活动之前保护（例如，锁定或加密）前台OS的文件。
