Embodiment 1
[0032] Referring to FIG. 1 , it includes a parent operating system module 1 , a sub-operating system module 21 , a sub-operating system module 22 , a system isolation module 3 and an external storage access control module 4 .
[0033] The mother operating system module 1 may only include an operating system kernel for completing the most basic functions. The so-called operating system kernel refers to a software program used to provide the basic functions necessary for the operating system; the operating system kernel for completing the most basic functions may be Linux Or the kernel of Unix or Windows, Windows is taken as an example in this embodiment.
[0034] The mother operating system module 1 may also include the kernel and software programs other than the kernel, that is, include the kernel and application programs other than the kernel of the operating system, for providing the basic functions required by the operating system and other user-selected functions. For exam...
Embodiment 2
[0055]Referring to FIG. 5 , it is a schematic diagram of Embodiment 2 of the present invention, which implements operating system isolation under the virtual machine architecture. Under the computer architecture that supports virtual machine technology, the virtual memory management module (VirtualMemory Manager, referred to as VMM) is the core part of virtual machine technology, running under all other operating systems, and assigning and Coordinate system resources. For example, the VMWare software of VMWare Company, the Virtual PC software of Microsoft Corporation, and the Xen software of XenSource Company all support the virtual machine technology. Under the function of VMM, two or more operating systems can run simultaneously in the same computer system. In this embodiment, only one mother operating system module 1 is taken as an example, wherein the mother operating system module 1 is isolated by the system Module 3 guides and establishes two sub-operating system module...
Embodiment 3
[0059] Referring to FIG. 6 , it is a schematic diagram of another embodiment for implementing operating system isolation under the virtual machine architecture. The virtual machine system is provided with a management operating system module or a service operating system module 5 (called the secondary operating system module), which runs simultaneously with the parent operating system module 1 (also called the main operating system module) or precedes the parent operating system module 1 Run, monitor the state of the parent operating system module 1, and provide a disk access interface for the parent / child operating system module.
[0060] The system isolation module 3 is set in or outside the kernel of the secondary operating system module, and the startup sequence is: computer hardware startup; VMM startup; secondary operating system module and system isolation module startup; parent operating system module startup; sub-operating system module 21 and 22 activate one or more ...
