Detailed ways

In order to make the purpose, technical solutions and advantages of the application clearer, the application will be described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. It should be understood that the specific operation methods in the method embodiments described below may also be applied in the device embodiments or system embodiments.

The existing image management service includes the image files used to manage and activate virtual machines, including public image files and private image files. Wherein, the public image file refers to the image file generated in the current cloud platform. For example, a public image can be a type of operating system template. The public image can be used by unspecific users, and it can be used to provision virtual machines according to the user's needs. Correspondingly, a private image file refers to an image file generated on a platform other than the current cloud platform. When a user needs to import a private image file to the cloud platform and activate a virtual machine based on the private image file, the existing image management service cannot support the user to import image files from other cloud platforms, and can only be recreated by the user on the current cloud platform mirror file. For example, private images may include private images imported from other cloud platforms and/or private images generated based on public images. Private images can be used by some users or a single user.

Unless otherwise specified below, the image files in this application refer to private image files.

In order to solve the above problems, the present application provides a method for importing image files, which is used to meet the needs of users for importing image files on cloud platforms and improve the flexibility of obtaining image files.

In the embodiment of the present application, the image file and the format information of the image file are obtained. The image file is stored in the object storage resource pool of the cloud platform. According to the format information of the image file, it is determined that the format of the image file belongs to an image file format that allows importing into the block storage resource pool. The image file is imported from the object storage resource pool to the block storage resource pool of the cloud platform, and the image file can be used to provision a virtual machine in the block storage resource pool of the cloud platform. The method can meet the user's requirement for importing the image file of the cloud platform, and improves the flexibility of obtaining the image file.

It can be understood that a method for importing an image file provided in the present application may be executed by an image file importing device (hereinafter referred to as the importing device for short). For example, the apparatus may be a device or a component in the device used by the user to access the cloud platform, or may be a device capable of communicating with the device (such as a cloud platform server) or a component in the device. For example, the device may be a server, a processor, a chip, or an intelligent terminal and other devices capable of data analysis and processing.

As shown in Figure 1, the specific steps of the import method provided in the embodiment of this application include:

Step 101, acquire an image file and format information of the image file.

Optionally, step 101 includes: the user can import the image file to the importing device through the front-end operating system of the cloud platform. Correspondingly, the importing device can obtain the image file through the front-end operating system. Obtain the image file from the cloud platform that generates the image file or the storage device that stores the image file, and extract its format information according to the image file.

Exemplarily, the front-end operating system may include the yacos system. Therefore, the user can operate the yacos system to select the image file to be imported, and correspondingly, the yacos system can extract the format information of the image file.

Exemplarily, the cloud platform for generating the image file may include a kvm platform, a vmware platform, or a hyperv platform. Among them, the kvm platform is a cloud platform that supports full virtualization, the vmware platform is a cloud platform that provides server and/or desktop virtualization, and the hyperv platform is a cloud platform that provides hardware virtualization. For example, the importing device obtains the image file generated on the kvm cloud platform from the kvm platform. Specifically, the cloud platform includes: a front-end operating system for acquiring image files and format information of the image files.

The storage device storing the image file may specifically be a storage medium such as a hard disk, or may be a device including a storage medium, such as a device used by a user to access the cloud platform, without specific limitation.

Exemplarily, the format information of the image file may include raw image file format, qcow2 image file format, vhd image file format, vhdx image file format or vmdk image file format. Wherein, the raw image file format is an image image file format, the qcow2 image file format is a disk image file format, the vhd image file format is a disk image file format, and the vhdx image file format is a disk image file format, The vmdk image file format is a disk image file format.

It can be understood that the source of the image file is not limited in this application.

Step 102, storing the image file in the object storage resource pool of the cloud platform.

The object storage resource pool may be a storage resource pool used to store files in the cloud platform resource pool. The object storage resource pool only has the function of storing files, but not the function of processing files. The function of storing files in the object storage resource pool includes: storing the storage file in any storage bucket in the object storage resource pool, and providing the storage address corresponding to the storage file in the storage bucket according to the storage.

In addition, different from the object storage resource pool, the cloud platform resource pool may also include a block storage resource pool. It can be understood that the object storage resource pool and the block storage resource pool are different storage areas in the cloud platform resource pool. The block resource storage pool can provide storage functions, and can divide storage areas for virtual machines to use independently. Wherein, the files imported by the user to the cloud platform are generally stored in the object storage resource pool. The image file generally needs to be stored in the block storage resource pool, and the virtual machine is realized in the block storage resource pool. For example, block storage resource pools can be used to create cloud hard disks (including system disks and data disks), and the cloud hard disks can be used to activate virtual machine resources and/or be mounted to a virtual machine for use.

Optionally, the importing device may store the image file in a storage bucket of the object storage resource pool, and obtain a storage address corresponding to the image file. Further optionally, the device can also display the corresponding storage address of the image file to the user through the front-end operating system. For example, the storage address is a uniform resource code (Uniform Resource Locator, URL). The URL may be used to indicate the storage bucket address and/or the storage file address.

Step 103, according to the format information of the image file, determine that the format of the image file belongs to the image file format that allows importing into the block storage resource pool.

Optionally, the importing device may create a database entry corresponding to the image file in the cloud platform according to the image management component in the cloud platform. Wherein, the image management component may be a cloud platform service component for executing image file import. For example, the importing device executes the _CreateImage command through the image management component to create a database entry in the cloud platform.

Exemplarily, in step 103, the importing device may extract the format information of the image file according to the storage address corresponding to the image file.

Optionally, the importing device may call a command in the image management component to check the format information of the image file. For example, the importing device can view the format information of the image file through the qemu-img info command.

Optionally, the importing device determines the image file allowed to be imported according to the image file format allowed to be imported into the block storage resource pool.

The image file formats that are allowed to be imported into the block storage resource pool can be stored as a list, so the importing device can look up the table according to the format information of the image file to be imported to determine whether the format of the image file to be imported belongs to the format of the image file that is allowed to be imported in this format , to avoid importing image files with wrong formats or formats not supported by the cloud platform. For example, the formats of image files that are allowed to be imported include raw format, qcow2 format, vhd format, vhdx format, and vmdk format, and if the format of the image file to be imported is raw format, then the format of the image file to be imported belongs to the allowed import format. For the format of the image file in this format, the importing device can determine that the image file is allowed to be imported.

Optionally, the image file format (or the list) allowed to be imported into the block storage resource pool may be preset. For example, it can be the internal configuration of the cloud platform, which can be set or updated by the operation and maintenance personnel of the cloud platform, and this application does not make specific requirements.

Optionally, if the importing device determines that the image file is not allowed to be imported according to the list of image file formats allowed to be imported into the block storage resource pool, for example, the format of the image file does not belong to the image file format of the imported block storage resource pool, then import The device may delete previously created database entries.

Here, the implementation process of step 103 is described by taking an example. In step 103, the importing device may extract an image file corresponding to the URL from the storage bucket according to the URL storage address. If the importing device determines that the image file is in qcow2 format, and determines that the qcow2 format belongs to the image file format allowed to import block storage resource pools according to the list of image file formats allowed to be imported into the block storage resource pool, then the importing device may It is determined that the image file is an image file allowed to be imported.

Step 104, import the image file from the object storage resource pool into the block storage resource pool of the cloud platform, and the image file is used to provision a virtual machine in the block storage resource pool of the cloud platform.

Optionally, the importing device can convert the format of the image file to be imported, and then import the converted image file into the block storage resource pool, or, after importing the image file to be imported into the block storage resource pool, perform format convert.

For example, the format of the image file to be imported is the first format, that is, the format information of the image file indicates that the format is the first format, and the format of the converted image file is recorded as the second format, which can be supported by the cloud platform. The format of the image file. For example, the format of the image file generated on the current cloud platform is the second format. It can be understood that the first format and the second format here belong to the image file format that allows importing the block storage resource pool.

For example, the first format is qcow2 format, and the second format is raw format. The image file formats allowed to import block storage resource pools include raw format, qcow2 format, vhd format, vhdx format, and vmdk format. Convert the format to raw format, and then import the image file into the block storage resource pool.

Optionally, when performing format conversion, the importing device may invoke the qemu-imgconvert command through the image management component to convert the image file in the first format into the image file in the second format.

In addition, if the first format is the same as the second format, the importing device can import the image file into the block storage resource pool without format conversion.

For example, as shown in FIG. 2 , the user can start the image file import process through the front-end management system, and upload the image file to the object storage resource pool in the resource pool of the cloud platform. In the process of importing the image file, the importing device imports the image file in the object storage resource pool into the block storage resource pool through the image management component, so as to realize the above steps 101 to 104.

For example, as shown in Figure 3, the importing device can call at least one of the _CreateImage command, _ImportToStore command, and qemu-img convert command, _SaveImage command and _CompleteTask command through the image management component, to achieve the above steps 103 to 104 , this process may be referred to as an image import subtask flow.

Based on the process shown in FIG. 2 , the embodiment of the present application provides a method for importing an image file, which can improve the flexibility of an image file acquisition method to meet user needs.

In addition, the import process adopts the method of file flow, and uses tools such as qemu-img to import the image file in the object storage into the block storage pool of the cloud platform, which will not occupy the storage space resources of the physical machine where the image management component is located.
