Communication protocol implementation method and device for virtualization environments

Abstract

The invention discloses a communication protocol implementation method and device for virtualization environments. The communication protocol implementation method comprises the following steps: adding virtio-serial equipment to a client; adding a kernel module to the client, wherein the kernel module is used for realizing a communication protocol; modifying a calling function of the client according to the kernel module so as to realize data transmitting and receiving between the client and a host. As the kernel module and the virtio-serial equipment are added into the client, no-network communication between the host and the client is realized, and much modification of programs is avoided.

Description

technical field [0001] The invention relates to the computer field, in particular to a method and device for realizing a communication protocol used in a virtualized environment. Background technique [0002] In the server virtualization environment (server virtualization technology refers to the technology that can run multiple virtual servers (clients) on one physical server (host), it can not only improve the utilization of server resources, but also enhance system security. and reliability), a host usually runs multiple clients, and for security reasons, the resources of the host and the virtual machine are isolated. However, in the actual use process, there is often a need for communication between the two. In this case, the following two methods are generally included in the prior art. One is to configure the virtual network card in the client and perform related network settings. , and then use socket (socket) technology to write related applications or use existing ...

Problems solved by technology

[0003] However, for the above method of configuring a virtual network card, in some usage scenarios, the client may not have a virtual network card configured for some reason, or due to some firewall policies, the host or client cannot accept external requests, then, at this time The host computer and the client computer cannot communicate through the network

[0004] When using a fully simulated serial port for communication, due to the low bandwidth of the serial port communication, it is impossible to complete the communication of a large amount of data. Modify the network program and change the general socket process to the file open / read / write mode. This modification is not flexible enough, and it will bring a large workload in many scenarios.

[0005] For the above-mentioned problems in related technologies, no effective solution has been proposed yet
