Cloud System Data Management Method and Apparatus

摘要

A cloud system data management method for alleviate a data leakage problem occurring when a user accessed by another user when a virtual data volume of the user is mounted to a virtual machine of another user includes creating a first virtual machine for a user and allocating a virtual data volume to the first virtual machine, setting an identifier of the virtual data volume as an identifier corresponding to a home identifier of the first virtual machine, determining, according to the identifier of the virtual data volume and a home identifier of a second virtual machine, whether the virtual data volume and the second virtual machine belong to a same user when the virtual data volume needs to be mounted to the second virtual machine, forbidding the virtual data volume to be mounted to the second virtual machine when they do not belong to the same user.

主权项

1. A cloud system data management method, comprising:
creating a first virtual machine for a user; allocating a virtual data volume to the first virtual machine, wherein the first virtual machine has a home identifier, and wherein the home identifier of the first virtual machine is used to identify a user to which the first virtual machine belongs; setting an identifier of the virtual data volume as an identifier corresponding to the home identifier of the first virtual machine; determining, according to the identifier of the virtual data volume and a home identifier of a second virtual machine, whether the virtual data volume and the second virtual machine belong to a same user when the virtual data volume needs to be mounted to the second virtual machine; and forbidding the virtual data volume to be mounted to the second virtual machine when the virtual data volume and the second virtual machine do not belong to the same user.
