Abstract
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.
