Embodiment Construction

[0028] There are many implementations of the present invention, here we take the desktop cloud platform as an example to illustrate one of the implementation methods, the flow chart is as follows figure 1 As shown, the specific implementation process is as follows

[0029] 1. Check the partition usage, the process is as follows:

[0030] 1) Check the file system information;

[0031] 2) Filter out non-partition information, and the rest are partition information;

[0032] 3) Query the list of virtual machines based on the original image.

[0033] 2. Create a new image, the process is as follows:

[0034] 1) Obtain the size of the original image;

[0035] 2) Create a new image file with the same size as the original image.

[0036] 3. Modify the new mirror partition, the process is as follows:

[0037] 1) Close all virtual machines based on the original image;

[0038] 2) Determine the modification method, if it is a shrink operation, then judge whether the available spa...

Abstract

The invention relates to the technical field of desktop cloud image management, in particular to a method for modifying a virtual machine image partition. The method of the invention is to create a new mirror image according to the queried virtual machine partition situation, and modify the partition of the new image as needed; replace the original image with a new one. The invention solves the problems that the mirror image partition cannot be automatically modified, the mirror image cannot be compressed, the virtual machine which is using the mirror image cannot be effective, the size of themirror image partition cannot be reduced, and the like. The method can be applied to the field of desktop cloud image management technology.

Description

technical field [0001] The invention relates to the technical field of desktop cloud image management, in particular to a method for modifying a virtual machine image partition. Background technique [0002] Now more and more desktop cloud platforms have been applied to various enterprises, and the needs of each enterprise are very personalized; many require the use of existing servers, such as creating cloud desktops based on existing servers; in this way The disk configuration of the cloud desktop usually also needs to be personalized. The traditional method mainly uses manual methods to create cloud desktops with disk partitions that meet customer requirements and provide them to users. This will cause the following hidden dangers: [0003] One is that when there are more and more desktop cloud projects, the image must be manually recreated according to each customer's needs. In fact, the software and operating system of the cloud desktop are the same, but the disk part...
