Abstract: PURPOSE: A device and a method for synchronizing a snapshot image are provided to reduce an initial booting time by performing booting based on the snapshot image. CONSTITUTION: A first storage(101) stores status information related to the execution state of a system. If the system is booted based on the status information, a second storage(102) loads one part among status information according to the process execution of the system. If the process varies one part of the status information which is loaded in the second storage, a synchronization unit(103) detects a synchronization page corresponding to the changed part and reflects the synchronization page in the status information which is saved in the first storage during the idle state of the system.
Abstract translation: 目的：提供用于同步快照图像的设备和方法，以通过基于快照图像执行引导来减少初始引导时间。 构成：第一存储（101）存储与系统的执行状态相关的状态信息。 如果基于状态信息引导系统，则第二存储器（102）根据系统的处理执行在状态信息中加载一部分。 如果该过程改变加载在第二存储器中的状态信息的一部分，则同步单元（103）检测与改变的部件相对应的同步页面，并将同步页面反映在保存在第一存储器中的状态信息中 系统的空闲状态。

Abstract: A method and a device for processing access to a disk block are provided to improve performance by sharing a cache between OS(Operating System) domains through memory access control in a VMM(Virtual Monitor Machine) environment without copying data and prevent data collision by performing access control for a disk drive in a device domain. A device domain(210) receives an access request to a disk block from one OS domain(200,220), determines permission of the access request to the disk block by referring to a block table(212), and processes disk block access of the OS domain depending on a determination result. The device domain includes the block table including more than one of a lock type, a lock holder, a home node, and a page address of the disk block. The device domain requests updating a page table of the OS domain to a VMM(230) to share a page of the disk block and returns the page address shared by updating the page block to the OS domain when the disk block is cached to other OS domain. The device domain accesses a disk drive(240) and enables the disk drive to copy data of the data block to the page of the OS domain when the disk block is not cached to other OS domain.
Abstract translation: 提供用于处理对磁盘块的访问的方法和设备，以通过在VMM（虚拟监视器机器）环境中的存储器访问控制在OS（操作系统）域之间共享高速缓存来提高性能，而不复制数据并通过执行 设备域中磁盘驱动器的访问控制。 设备域（210）从一个OS域（200,220）接收对磁盘块的访问请求，通过参考块表（212）来确定对该磁盘块的访问请求的许可，并且处理OS的磁盘块访问 域取决于确定结果。 设备域包括包含锁定类型，锁定保持器，家庭节点和磁盘块的页面地址中的多个的块表。 设备域请求将OS域的页表更新到VMM（230），以共享磁盘块的页面，并且当磁盘块被缓存到其他操作系统时，将通过更新页面块的页面块返回到OS域 域。 当磁盘块未被缓存到其他OS域时，设备域访问磁盘驱动器（240）并使磁盘驱动器可以将数据块的数据复制到OS域的页面。
