摘要： Provided is a method of controlling memory access. In a system including a first layer element executed in a privileged mode having a first priority of permission to access the entire region of a memory and second and third layer elements executed in an unprivileged mode having a second priority of permission to access a partial region of the memory, the method of controlling memory access determines whether the memory is accessible for each page that is an address space unit, based on which mode a layer element currently accessing the memory is executed in between the privileged mode and the unprivileged mode; and determines whether the memory is accessible based on which one of the first, second and third layer elements corresponds to a domain currently being attempted to be accessed from among a plurality of domains of the memory. Accordingly, a memory domain allocated to a guest operating system kernel is effectively protected from an application executed in the unprivileged mode in which the guest operating system kernel is executed.

摘要： Provided are a method and a system for processing an access to a disk block. The system receives a disk block access request from an OS domain, determines whether the OS domain is permitted to access a disk block with reference to a predetermined block table and processes disk block access of the OS domain according to the determination result. Accordingly, OS domains can share caches without having data copy through memory access control in a virtual machine monitor environment. Furthermore, a device domain controls access to a disk drive so that data corruption can be prevented.
摘要翻译：提供了一种用于处理对磁盘块的访问的方法和系统。系统从OS域接收磁盘块访问请求，确定OS域是否被允许参照预定的块表访问磁盘块，并根据确定结果处理OS域的磁盘块访问。因此，OS域可以共享高速缓存，而无需通过虚拟机监视环境中的存储器访问控制进行数据复制。此外，设备域控制对磁盘驱动器的访问，以防止数据损坏。

摘要： Provided is a method and apparatus for storing and restoring a state of a virtual machine on a virtual machine monitor. The method of storing a state of a second virtual machine in a predetermined storage device by a first virtual machine on a virtual machine monitor includes determining whether the state of the second virtual machine has changed, by comparing a previous state of the second virtual machine, which has already been stored in the storage device, with a current state of the second virtual machine and selectively storing the state of the second virtual machine based on a result of the determination, thereby minimizing time required to store or restore the state of the second virtual machine.
