Abstract

Embodiments of the present invention relate to a method, device, and electronic device for sharing a file system with multiple operating systems. The method includes: the client operating system writes request data to a preset shared memory space, and the preset shared memory space supports at least Two operating systems access; notify the server operating system of the access request of the client operating system; the server operating system queries the request data in the preset shared memory space, and sends the request data to the Writing reply data into the preset shared memory space; notifying the client operating system of a reply from the server operating system; obtaining the reply data from the preset shared memory space by the client operating system, And mount the target folder in the server operating system to the client operating system according to the reply data. The embodiment of the present invention can realize file system sharing between virtual machines and between virtual machines and host machines.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of virtualization, for example, to a method, device and electronic device for sharing a file system among multiple operating systems. Background technique [0002] Virtualization technology can enable multiple operating systems to share the hardware resources of the machine, and each operating system is independent of each other and does not affect each other. It not only plays a good isolation role, but also greatly improves the resource utilization of the system. In some application scenarios, file systems need to be shared between virtual machines or between a virtual machine and a host. At present, the file system of the host machine is mainly shared with the virtual machine system through virtio, and the virtual machine mounts the file system of the host machine to the virtual machine through 9pfs of the kernel. [0003] In the process of researching the existing technology, the ...
