Virtual machine internal and external interaction method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a virtual machine internal and external interaction method and device, electronic equipment and a storage medium. The method comprises the steps that serial port simulation equipment is generated in a virtual machine in a hardware virtualization mode; a simulation pipeline is generated outside the virtual machine in a hardware virtualization mode; and performing data interaction between the virtual machine internal program and the virtual machine external program based on the serial port simulation equipment and the simulation pipeline. By directly modifying the program of the virtual machine, simulating the universal serial port on the virtual machine and simulating the pipeline outside the virtual machine, data exchange between the internal program and the external program can be achieved through the universal interface, the method is achieved based on simulation of universal hardware, program developers do not need to modify internal and external interaction program codes again, and the method is simple and convenient to operate. The integrity and stability of an operating system are not affected, stable, reliable and rapid data transmission can be realized, and good support can be provided for internal and external data exchange of the virtual machine.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, device, electronic device and storage medium for interacting inside and outside a virtual machine. Background technique [0002] The data exchange inside and outside the virtual machine is one of the main problems to be solved by the software analysis tool based on the virtual machine. At present, data exchange inside and outside the virtual machine mainly includes data exchange method based on shared memory and data exchange method based on network (socket). [0003] The data exchange method based on shared memory is a traditional data exchange scheme. The current VMWare virtual machine and VirtualBox virtual machine mainly realize data exchange through shared memory. It does this by installing a driver in the system that marks a specific memory area of ​​the virtual machine as a swap area. When external data exchange is required, a corresponding reque...

AI Technical Summary

Problems solved by technology

Due to the simulation problem of the virtual machine itself, the socket is often unstable. After the disconnection, due to the influence of the network protocol timeout and other mechanisms, even if the disconnection is detected, the fast connection recovery cannot be achieved.

Therefore, it is difficult to achieve stable and fast data exchange inside and outside the virtual machine based on the network

[0004] It can be seen that whether it is based on memory mapping or network-based data exchange methods, there is a heavy workload, it is difficult to ensure efficiency and stability in the data connection and transmission process, the scalability is poor, and it is difficult to achieve agile, stable and scalable data. Exchange defects, so it is difficult to meet the needs of stable and reliable data exchange inside and outside the virtual machine
