Approximately 75% of the production environment ceph serves as a storage back end of openstack, and components including nova, circular, manila and gland can use ceph, wherein the gland uses the block storage of ceph as a mirrored storage back end. openstack uses ceph as the storage back-end, and the nova, glance, and cinator components are generally divided into different pool for use. For example, assuming nova uses poolvms and liance uses poolmages, when creating a virtual machine from an image, images to vms are needed, and to ensure high performance and not occupy the storage space of a compute node, a copy method of ceph is directly used to perform operations at the ceph level.

Detailed Description
In the cloud computing era, with the continuous expansion of the market scale of the internet, a large number of heterogeneous resources are uniformly managed through a cloud platform. When a virtual machine is created on a cloud platform, a local image needs to be uploaded to the cloud platform.
The current mirror image uploading process is shown in fig. 1, and may specifically include the following 4 steps:
(1) the mirror image stored locally by the user is uploaded to the UI module of the cloud platform through the management network through the uploading interface, and the operation such as gateway shunting, authority authentication and the like can be performed in the middle.
(2) And (3) forwarding the data stream passing the verification in the step (1) to the cloud platform IMAGE module through the management network by the UI module of the cloud platform.
(3) After caching the mirror IMAGE file, the cloud platform IMAGE module calls a GLANCE interface of OPENSSTATK through a management network, and the mirror IMAGE is uploaded to a GLANCE control node. The process needs to pass the INGRESS forwarding and KEYSTONE authentication of OPENSACK.
(4) The GLANCE control node stores the mirror image to the configured storage node and finishes mirror image registration in the database.
However, the above-mentioned existing mirror last time approach has three disadvantages: firstly, when the mirror image is large, the flow of the management network can influence the calling speed of the cloud pipe platform interface; secondly, the time consumption of the uploading process is large due to the fact that the middle process is subjected to four data moving processes; thirdly, if the user accidentally turns off the browser in the uploading process or interrupts the uploading process, the user needs to upload again from the beginning, which also results in poor user experience. Therefore, how to optimize the uploading process of the virtual machine image so that the virtual machine image can be quickly imported into the storage node of the database is an urgent problem to be solved at present.
In order to solve the above defect, an embodiment of the present application provides a method for quickly importing a virtual machine image, where a target virtual machine image is determined first, and the target virtual machine image is uploaded to an object for storage, then an empty image corresponding to the target virtual machine image is uploaded through a cloud platform, an empty image file is created in a storage node according to the empty image, attribute information and metadata information of the target virtual machine image are stored in a database, and then the target virtual machine image can be copied from the object for storage to the empty image file of the storage node. Therefore, the virtual machine mirror image can be uploaded to the object storage through the storage network directly, when the cloud platform uploads the virtual machine mirror image, the transmission link of the mirror image data stream is reduced, the uploading time is shortened, meanwhile, the flow of the management network is not occupied, the success rate of mirror image uploading is improved, the virtual machine mirror image is uploaded quickly and efficiently, and the user experience is improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First embodiment
Referring to fig. 2, a schematic flowchart of a method for quickly importing a virtual machine image provided in this embodiment is shown, where the method includes the following steps:
s201: and determining a target virtual machine image, and uploading the target virtual machine image to an object storage.
It should be noted that, in the current distributed storage field, there are three disadvantages to the mirror upload flow shown in fig. 1: firstly, when the mirror image is large, the flow of the management network can influence the calling speed of the cloud pipe platform interface; secondly, the time consumption of the uploading process is large due to the fact that the middle process is subjected to four data moving processes; thirdly, if the user accidentally turns off the browser in the uploading process or interrupts the uploading process, the user needs to upload again from the beginning, which also results in poor user experience.
Therefore, in this embodiment, in order to realize fast and efficient uploading of the virtual machine image to improve the user experience, the target virtual machine image is determined first, and the target virtual machine image is uploaded to the object storage to continue to execute the subsequent steps S202 and S203.
The object storage refers to an object/file-oriented massive internet storage, and may also be directly referred to as "cloud storage". Although the object is a file, it is an encapsulated file (the object in programming has the characteristic of encapsulation), that is, in the object storage system, the file cannot be directly opened/modified, but the file can be uploaded and downloaded like ftp. In addition, the object storage does not have a file structure with a plurality of levels like a file system, but only has the concept of a 'bucket' (namely storage space), and all objects in the 'bucket' are objects, so that the object storage is a very flat storage mode. The main characteristic is that the name of its object is a domain name address, once the object is set as "public", all users can access it; its owner may also access objects therein by way of the REST API. Therefore, the object storage is a more mainstream usage scenario, that is, static content (videos, pictures, files, software installation packages, and the like) of internet/mobile internet applications such as websites and mobile apps is stored.
And OpenStack in fig. 1 refers to an open-source cloud computing management platform project.
An optional implementation manner is that, in step S201, an implementation process of "uploading the target virtual machine image to the object storage" may specifically include: and directly uploading the target virtual machine mirror to the object storage through an Amazon S3 interface through a storage network.
Specifically, in this implementation, after determining the target virtual machine image that the user needs to upload, the target virtual machine image that needs to upload is first uploaded to the object storage directly through the storage network via the Amazon S3 interface, and since the storage network has a large width ratio and the data stream in this process is not split by other forwarding, the transmission speed is fast.
Wherein, Amazon S3 refers to Amazon Simple Storage Service for short, and is also an internet Storage solution. This service is intended to reduce the difficulty of developers performing network scale level calculations. Amazon S3 provides a simple Web services interface that can be used to store and retrieve any amount of data anywhere on the Web at any time. The service enables all developers to access the same data storage infrastructure with high expansibility, reliability, safety, rapidness and low price.
S202: the method comprises the steps of uploading a null mirror image corresponding to a target virtual machine mirror image through a cloud platform, creating a null mirror image file in a storage node according to the null mirror image, and storing attribute information and metadata information of the target virtual machine mirror image in a database.
In this embodiment, in order to reduce a transmission link of a target virtual machine image, shorten an upload time, simultaneously not occupy a management network traffic, and improve an upload success rate of the target virtual machine image, after the target virtual machine image is uploaded to an object for storage in step S201, further, an empty image corresponding to the target virtual machine image may be uploaded through a cloud platform, an empty image file is created in a storage node according to the empty image, and attribute information (for example, attribute information such as a memory size and a hard disk size required for creating an operating system using the virtual machine image) and metadata information of the target virtual machine image are stored in a database, so as to perform subsequent step S203.
An optional implementation manner is that the specific implementation process of step S202 may include the following steps a to D:
step A: the method comprises the steps of uploading an empty mirror image corresponding to a target virtual machine mirror image through a cloud platform, obtaining an information flow corresponding to the target virtual machine mirror image according to the empty mirror image, and uploading the information flow to a UI server of the cloud platform after the information flow is subjected to ingress load distribution and gateway authentication.
In the implementation mode, when the empty mirror image corresponding to the target virtual machine mirror image is uploaded through the cloud platform, the web page reads the target virtual machine mirror image data, acquires the information flow corresponding to the target virtual machine mirror image according to the empty mirror image, distributes the information flow through the ingress loads, and finally uploads the information flow to the cloud management platform UI server through gateway authentication.
And B: and uploading the information stream to an image module of the cloud platform after passing gateway authentication through a UI server of the cloud platform, so that the image module stores the attribute information and the metadata information of the target virtual machine mirror image in a database.
And C: after the information stream is checked for quota validity through an image module of the cloud platform, the information stream is uploaded to a GLANCE module of a cloud operating system OPENSTACK, so that the ingress load distribution and the keystone authentication of the GLANCE module are facilitated.
Step D: creating an empty mirror image file in a storage node according to the empty mirror image through a GLANCE module; and completing the registration of the target virtual machine mirror image in the database by using the attribute information and the metadata information of the target virtual machine mirror image through the GLANCE module.
In the implementation manner, after receiving the information stream data, the chord module of the OPENSTACK stores the empty image file in the back end configured by the chord module, and registers the image information of the target virtual machine image in the database. That is, at this time, the chord module creates an empty image file in the storage node, and stores the empty image file in the ceph image pool configured by the chord module.
In this way, since the information stream data uploaded in the steps a-D are all empty files, no long time is consumed.
S203: and copying the target virtual machine image from the object storage to an empty image file of the storage node.
In this embodiment, after the target virtual machine image is uploaded to the object storage in step S201 and the empty image file is created in the storage node in step S202, the target virtual machine image may be further copied from the object storage to the empty image file of the storage node.
Specifically, after the target virtual machine image is uploaded to the object storage and an empty image file is created in the storage node, further, the target virtual machine image may be copied from the object storage to the empty image file in the ceph image pool configured by the chord module using the rbd client of the ceph cluster, that is, the empty image file is overwritten by the target virtual machine image, so as to realize fast import of the target virtual machine image.
Further, after checking whether the state of the mirror image of the target virtual machine is normal, it can be determined whether mirror image service can be provided to the outside, that is, when the state of the mirror image of the target virtual machine is normal, mirror image service can be provided to the outside.
To facilitate understanding of the method for quickly importing a virtual machine image provided by the present application, the present application will next describe, with reference to fig. 3, an overall flow of the method for quickly importing a virtual machine image based on object storage according to the embodiment of the present application:
as shown in fig. 3, the method for quickly importing a virtual machine image provided in the embodiment of the present application specifically includes: first, the virtual machine image to be uploaded is directly uploaded to the object storage through the storage network via the Amazon S3 interface, as shown in step 0 marked in fig. 3, since the storage network has a large width ratio and the data stream of this process is not split by other forwarding, the transmission speed is fast.
Then, an empty mirror image is uploaded through the cloud management platform, at this time, the web page reads local mirror image data of the user, and the local mirror image data is subjected to ingress load distribution, then is finally uploaded to the cloud management platform UI server through gateway authentication, as shown in step 1 marked in fig. 3.
Then, the cloud management platform UI server uploads the data stream to the cloud management platform image module after passing through gateway authentication, and the cloud management platform image module records information such as mirror image information and metadata in the database, as shown in step 2 marked in fig. 3.
Furthermore, after the Image module checks quota validity and the like of the mirror Image data, the Image module uploads the data to the GLANCE module of the OPENSTACK. This requires ingress load shedding and keystone authentication through the OPENSTACK module, as shown in step 3 labeled in FIG. 3.
Further, after the data stream is received by the chord module of the OPENSTACK, the mirror image file is stored in the rear end configured by the chord module, and the mirror image information is registered in the database. At this time, the chord module will create an empty image file in the storage node, and since the data stream uploaded in these steps is an empty file, it will not take too long, as shown in step 4 marked in fig. 3. And finally, finding the position of the previously uploaded empty file through the storage network and the rbd client by using the real mirror image, and directly covering the empty file by copying the real mirror image, as shown in a step 5 marked in the figure 3.
Therefore, after a reasonable mirror image uploading strategy is designed, the virtual machine mirror image can be uploaded quickly and efficiently through the cloud platform.
