Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0042] The method for expanding the disk capacity of a virtual machine online in the embodiment of the present invention and the virtual system console can run in a virtual environment installed with a virtual machine, which includes but is not limited to, for example, VirtualBox (developed by InnoTek, a German software company) The virtual system software developed was later acquired by Sun and renamed as Sun Virtual Box. Virtual systems include various versions of Windows, Mac OS X, Linux, OpenBSD, Solaris, IBM OS2 and Androi...

Abstract

The invention discloses a method for on-line extension of the disk size of a virtual machine and a virtual system console. The method comprises the steps that the console obtains information for expanding the disk size of the virtual machine, the information for expanding the disk size comprises an identification label number of the virtual machine and the size of a disk expansion space applied by a virtual machine disk, a disk expansion space is generated in a storage disk according to the size of the disk expansion space applied by the virtual machine disk and on the basis of a preset distribution rule, and the virtual machine needing expansion of the disk size is found according to the analyzed identification label number of the virtual machine; configuration information of the virtual machine is modified and stored according to the property of the disk expansion space, and the disk expansion space of the storage disk is distributed to the disk of the virtual machine. According to the method, on-line extension of the disk size of the virtual machine can be conducted without interrupting an operation system of the virtual machine, and therefore continuity of service of the virtual machine is guaranteed.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a method for online expansion of disk capacity of a virtual machine and a virtual system console. Background technique [0002] Virtualization is to virtualize the physical resources of the server into logical resources, so that one physical server becomes several or even hundreds of virtual servers isolated from each other, thereby improving the utilization rate of hardware resources, simplifying system management, realizing server integration, and allowing users It can meet the needs of various new businesses or expanded businesses at the lowest cost, so it has attracted more and more attention from all over the world. [0003] A 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. The virtual platform built on it. [0004] Since the virtual machine is based ...
