Inter-offline virtual machine file sharing method and device

Abstract

The invention provides an inter-offline virtual machine file sharing method and device, which is used for solving the file sharing problem of offline virtual machines in offline states. The method comprises the steps of loading a first virtual disk mirror image corresponding to a first offline virtual machine and a second virtual disk mirror image corresponding to a second offline virtual machine in a management domain; and in the management domain, according to a file operation instruction, operating files in a first virtual disk and a second virtual disk. By loading file systems in the first virtual disk and the second virtual disk in the management domain and running the corresponding file operation instruction, shared access of the file systems between the first virtual machine and the second virtual machine in the offline states is realized.

Description

technical field [0001] The invention relates to communication technology / computer technology, in particular to a file sharing method and device among offline virtual machines. Background technique [0002] A virtual machine (Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Users do not need to spend a lot of money to purchase hardware, as long as they can achieve the computing purpose of multiple physical machines through the application of virtual machines. [0003] Multiple virtual machines running on a computer or server are independent of each other. Before a shared channel is built, multiple virtual machines cannot access each other's file systems. In a virtualization environment, a virtual machine in a shutdown state is called an offline virtual machine. Correspondingly, a virtual machine in a power-on state is called an online virtual machine....

AI Technical Summary

Problems solved by technology

[0006] The first disadvantage is that the two virtual machines that need to share files must be powered on at the same time, and only the virtual machines in the powered-on state can share files through network sharing.

[0007] The second disadvantage is that the two virtual machines that need to share files must communicate with each other through the network (or the network is reachable)

[0009] Shortcoming one refers to the shortcoming one in the above method one

[0010] The third disadvantage is that the two virtual machines that need to share files must install and run the relevant file sharing agent (or client) software, and the virtual machines that have not installed or are not running the relevant file sharing agent (or client) software cannot perform file sharing. shared

[0011] The fourth disadvantage is that the file sharing agent (or client) software consumes virtual machine computing resources

That is, when sharing files, you need to run related file sharing agent (or client) software, thus consuming resources on the guest virtual machine
