    • Machine-readable media, methods, apparatus and system for booting a processing system are described. In an embodiment, whether an encrypted version of a closed operating system is authentic may be determined. The encrypted version of the closed operating system may be decrypted with a key retrieved from a processor register to provide the closed operating system, based at least in part on a determination that the encrypted version of the closed operating system is authentic. Then, whether the closed operating system is authentic may be determined and a virtual machine may be created so that the closed operating system may be launched in the virtual machine, if the closed operating system is authentic.
    • 描述了用于引导处理系统的机器可读介质,方法,装置和系统。 在一个实施例中,可以确定封闭操作系统的加密版本是否可信。 至少部分地基于关闭操作系统的加密版本是真实的确定,可以用从处理器寄存器检索的密钥来解密封闭操作系统的加密版本以提供封闭操作系统。 然后,可以确定封闭的操作系统是否是真实的,并且可以创建虚拟机,以便如果封闭的操作系统是真实的,则可以在虚拟机中启动关闭的操作系统。

    • In one embodiment, a method includes receiving control of a first processor transitioned from a virtual machine due to a privileged event pertaining to a translation-lookaside buffer, and determining which entries in a guest translation data structure were modified by the virtual machine. The determination is made based on metadata extracted from a shadow translation data structure maintained by a virtual machine monitor and attributes associated with entries in the shadow translation data structure. The metadata includes an active entry list identifying mappings that map pages used by a guest operating system in forming the guest translation data structure. The method further includes synchronizing entries in the shadow translation data structure that correspond to the modified entries in the guest translation data structure with the modified entries in the guest translation data structure, and determining which entries to keep in the active entry list, based at least in part on attributes associated with corresponding entries in the shadow translation data structure identifying which of the plurality of processors owns each entry in the active entry list.
    • 在一个实施例中,一种方法包括接收由于与翻译后备缓冲器有关的特权事件而从虚拟机转换的第一处理器的控制,以及确定客体翻译数据结构中的哪些条目被虚拟机修改。 基于从由虚拟机监视器维护的阴影翻译数据结构提取的元数据和与阴影翻译数据结构中的条目相关联的属性进行确定。 元数据包括标识映射的活动条目列表,其映射由客户操作系统在形成客体翻译数据结构中使用的页面。 所述方法还包括将所述客体翻译数据结构中与修改的条目相对应的影子翻译数据结构中的条目与访客翻译数据结构中的修改的条目同步,以及至少基于 部分地关于与阴影翻译数据结构中的对应条目相关联的属性,其识别多个处理器中的哪个处理器拥有活动条目列表中的每个条目。
