Communication method between virtual machine and host machine, host machine and virtual machine system

Abstract

The invention discloses a communication method between a virtual machine and a host machine, the host machine and a virtual machine system. A port file is assigned for the virtual machine by a port communication device which is arranged in the host machine and the port communication device starts host machine port communication services. The port file can be read, written and monitored by the host machine port communication services. Data interaction is performed between the virtual machine and the host machine through reading and writing of the port file. According to the communication method between the virtual machine and the host machine, the host machine and the virtual machine system, the port communication device, namely a port communication module, is added into the host machine and accordingly the communication between the virtual machine and the host machine can be achieved and an encrypted file which is arranged on the host machine is read and written and accordingly the communication between the virtual machine and the host machine can be achieved without TCP / IP (Transmission Control Protocol / Internet Protocol) network or under the condition that a firewall port is fully closed and accordingly the communication between applications inside the virtual machine and applications outside the virtualization environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of virtual machine applications, and in particular to a communication method between a virtual machine and a host machine, and a host machine and a virtual machine system. Background technique [0002] Server virtualization refers to a technology that virtualizes multiple virtual machines (VMs) on a physical host computer, and each virtual machine is isolated from each other and can run independently of each other at the same time. This technology splits a physical host machine into dozens of independent virtual machines, and each virtual machine can run business independently, which can achieve the goal of improving server resource utilization and management efficiency. As a basic technology of cloud computing, server virtualization technology has been widely applied and promoted in recent years. For example, an IDC (Internet Data Center: Internet Data Center) service provider virtualizes a physical host c...

AI Technical Summary

Problems solved by technology

[0004] 1. The virtual machine cannot communicate before the network configuration is completed or the network card is enabled;

[0005] 2. The virtual machine and the host machine are managed by different managers. They will establish firewall rules on their respective systems, but they do not know the ports that need to be opened, resulting in the inability to communicate between the virtual machine and the host machine.
