Virtual machine (VM) online antivirus system based on KVM virtualization platform

Abstract

The invention relates to a computer technology field and provides a virtual machine (VM) online antivirus system based on a KVM virtualization platform. A safety kernel module, a safety control module and a network module are arranged. A function which is used to read memory is added in a KVM kernel module. An interface of a safety kernel module registration hook is provided. The safety kernel module is used to register the hook in the KVM kernel module, emit a scanning command to the safety control module, accept a scanning surveillance result obtained by the safety control module, pause a suspicious process and carry out corresponding processing to the suspicious process. The safety control module calls an antivirus engine to carry out scanning surveillance to the process of all the VMs in the memory of the safety control module and reports the result to the safety kernel module. The network module is formed by a server network module and a client network module.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a virtual machine online antivirus system based on a KVM virtualization platform. Background technique [0002] With the development of the Internet, more and more large enterprises or laboratories tend to use virtualization architecture to save server costs or improve application flexibility. The essence of virtualization is to use many virtual machines to replace the original physical machines for various tasks. figure 1 Indicates the basic structure of virtualization, in which the bottom layer x86 Architecture (x86 structure) is the hardware device of the physical machine, including important processor (CPU), memory (Memory), network adapter (NIC), hard disk (Disk), etc. The second layer is the virtualization layer (Virtualization Layer), which is responsible for virtualizing the physical devices on the physical machine so that each virtual machine can be used. Each virtual...
