Problems solved by technology

[0008] (5) The image file of the virtual machine cannot realize intelligent management
[0009] From the analysis of the above problems, we can realize that if there are no corresponding isolation measures for the operation of virtual machines, there will be great security holes and hidden dangers. Therefore, if there is a method to realize effective management of virtual machines and realize The security isolation of virtual machines can greatly improve the reliability and robustness of virtual machines

Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Dynamic reservation and adjustment of virtual machine resources is one of the common requirements for using virtual machines. The present invention can dynamically start and shut down physical machines, and can also dynamically create and destroy virtual machines by realizing the effective reservation of physical machines and virtual machines. The security isolation of virtual machine storage involves various technologies, including the production of virtual machine image files, image file management, disk file management, disk partition technology, user authentication mechanism, rights management and distribution, etc.

[0038] see figure 2 , the dynamic reservation and adjustment of virtual machine resources include the following functions or technologies, management and allocation of resource reservation, setting of reservation rights, management and configuratio...

Abstract

The invention belongs to the field of computer security and relates to a virtual machine storage isolation technology based on disk virtualization and mirror intelligent management. Methods of intelligent management for mirror image files and virtual machine dynamic creation are provided to guarantee the virtual machine is positioned in different disk space so that effective isolation of storage is realized, which can be widely used in field of virtualization security. The technology comprises following steps: each virtual machine is positioned in different disk area or space; identity authentication is required when accessing virtual machine resource and random read-write of virtual machine files is forbidden; there is strict permission level between the virtual machines and host machines and random file sharing is forbidden; one virtual machine cannot access another virtual machine through the host machine. The security virtualization system comprises five core assemblies: a virtual machine monitor, a virtual machine simple disk based on volume snapshot, an operating system dynamic migration supervisor, a modification tracking supervisor and an implicit operating system information reconstruction assembly.

Description

technical field [0001] The invention belongs to the field of computer security, and relates to a virtual machine storage isolation technology based on disk virtualization and image intelligent management, which supports virtual machine operating systems such as Windows and Linux, and provides intelligent management of image files, virtual machine dynamic creation, management, Termination and other methods can ensure that virtual machines are in different disk spaces, thereby achieving effective isolation of storage, and can be widely used in the field of virtualization security. Background technique [0002] Nowadays, virtual machine technology can be divided into two directions according to the application and the correlation with the direct machine, namely system virtual machine (system virtual machine) and program virtual machine (process virtual machine). As the virtualization technology is more and more widely used, correspondingly, the security of the virtual machine b...
