Embodiment Construction

[0098] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0099] refer to figure 1 As shown, a driver isolation system inside a virtual machine includes: a driver isolation loading module running in a virtual machine user state, a memory information monitoring module in a virtual machine kernel state, and a memory access control module inside a virtual machine manager, wherein,

[0100] The driver isolation loading module running in the virtual machine user mode: establishes a connection between monitoring undefined symbols in the driver module and monitoring wrapping functions in the memory information monitoring module, so that the driver runs in isolation, and reports to the isolation in the memory information monitoring module The control submodule sends an isolated driver reminder message, so that the driver entering the kernel is an isolated driver; the monitoring undefined symbols include the undefined symbols of the...

Abstract

The invention discloses a driving separation system inside a virtual machine and a method and relates to a computer fault tolerant technology. The system, which is simple, effective and capable of being compatible with existing operation systems and a driving program framework and isolating a driving program inside the virtual machine based on a full virtualization technology, is achieved, the driving program isolating system inside the virtual machine comprises a driving isolation uploading module which runs in a user mode of the virtual machine, a memory information monitoring module in a kernel mode of the virtual machine and a memory access control module inside a manger of the virtual machine, and memory information monitoring module in the kernel mode of the virtual machine comprises a packaging function library, a isolation control submodule and an information communication submodule.

Description

technical field [0001] The invention belongs to the field of computer science and relates to computer fault-tolerant technology, in particular to a drive isolation system and method inside a virtual machine. Background technique [0002] For high-reliability computer systems, the reliability of the operating system is very important, but due to the high complexity of the operating system, its reliability is still a crucial but unsolved problem. Through the extensible mechanism of the operating system, a large number of drivers developed by third parties can be loaded into the kernel. At the same time, the macro-kernel architecture of the traditional operating system makes the driver and the kernel run in the same address space and privilege level, and any driver failure can be easily transmitted to other parts of the kernel, seriously weakening the reliability of the system. Because the driver accounts for a huge proportion of the kernel code and often lacks perfect testing...
