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： 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.
