Abstract

The embodiment of the invention discloses a system mirror image file updating method of a virtual machine. The system mirror image file updating method comprises the steps that when a virtual machine creating request is received, a target computing resource pool is selected from multiple computing resource pools, and a third virtual machine is created according to the target computing resource pool; on the condition that a system mirror image file of the third virtual machine is updated, data of a preset first system mother volume and incremental data of the system mirror image file are obtained; a new system mirror image file is synthesized based on the incremental data of the system mirror image file and the data of the first system mother volume; a second system mother volume of the third virtual machine is created in the target computing resource pool, and the new system mirror image file is stored in the second system mother volume; a second snapshot photo is generated according to the second system mother volume; a third linkage clone volume is created according to the second snapshot photo, and the third virtual machine is started according to the third linkage clone volume. The embodiment of the invention further discloses a cloud data center and a system. By the adoption of the system mirror image file updating method, the system mirror image file updating time is shortened, and storage space is reduced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for updating a system image file of a virtual machine, a cloud data center and a system. Background technique [0002] In the current cloud data center, it usually includes computing server, object storage server, image file service, authentication service, user interface service, etc. Among them, the image file service item is the virtual machine image file search and retrieval system, and provides the user's virtual machine with a system image file to meet the user's needs for the operating system. The image file space can load Ubuntu, windowsXP, centos and other operating systems. Each operating system has different versions, and usually the number of image files is very large. [0003] During the operation of the cloud data center, when the image file needs to be updated, the administrator needs to make and distribute the new image file, and then import the new image file ...
