Description
Technical Field
The application relates to the technical field of cloud desktops, in particular to a cloud desktop starting method and device.
Background
In the application field of cloud desktop software, there is an application that needs to distribute desktop images quickly. The essential principle is as follows: based on a shared virtual machine file (Base virtual machine), a large number of virtual machines are quickly cloned in batches for users to use. Typically, the operating system and necessary software already exist in the shared virtual machine files. The cloned virtual machine completely inherits the systems and software, so that all users can use the desktop with consistent experience. The use scenes of the functions are common in colleges, libraries, training institutions and the like.
As the scale of cloud desktop systems continues to increase, the carrying capacity of a physical server is limited. Fast cloning of desktop images beyond the size of a single server needs to be carried through the cluster. At this time, in order to enable all servers to perform fast cloning based on the same Base virtual machine file, the shared Base virtual machine is generally borne by means of shared storage and distributed storage. Therefore, all servers can access the same storage, and respective rapid cloning of the servers is realized.
However, this method has the following problems:
because the Base virtual machine is stored in the shared storage, when all servers perform batch fast cloning concurrently, huge storage IO pressure and network load are caused, and the network bandwidth is likely to run out, resulting in slow speed. The larger the scale, the more pronounced the bottleneck.
When the storage network fails or the shared storage is closed due to human factors, the rapid cloning cannot be performed.

The cluster structure provided by the embodiment of the present application is described below with reference to a specific application scenario, for example, as shown in fig. 1, a schematic diagram of a cluster structure provided by the embodiment of the present application is shown, where the cluster includes a shared storage server and a plurality of service servers (e.g., service server 1, service server 2, … …, service server n), each service server is in communication connection with the shared storage server, the shared storage server stores virtual machine images (e.g., virtual machine image 1, virtual machine image 2, … …, virtual machine image m) corresponding to a plurality of types of services, respectively, and maintains a hot virtual machine image list, each service server may obtain a hot virtual machine image from the shared storage server in advance and cache the hot virtual machine image locally, when it is determined that a batch cloud desktop starting operation needs to be performed based on a certain hot virtual machine image, the hotspot virtual machine image does not need to be acquired from the shared storage server.
Exemplarily, referring to fig. 2, a detailed flowchart of a cloud desktop booting method provided in an embodiment of the present application is shown, where the method is applied to a service server in a cluster, where the cluster further includes a shared storage server, where the shared storage server stores virtual machine images corresponding to multiple types of services respectively, and maintains a hot virtual machine image list, and the service server is in communication connection with the shared storage server, and the method includes the following steps:
step 200: and sending a hot virtual machine image list query request to the shared storage server based on a preset period so as to acquire the hot virtual machine image list from the shared storage server.
In practical application, a virtual machine template (i.e., a virtual machine image) is stored in a shared storage (shared storage server) in a cluster, the virtual machine image stored in the shared storage server can be accessed by all service servers in the cluster, a virtual machine created and started based on one type of virtual machine can provide a corresponding type of service, and the service servers can perform batch cloning and starting based on any virtual machine image. In the embodiment of the application, the shared storage server may mark the hot virtual machine image corresponding to the hot service based on the preset rule and generate the corresponding hot virtual machine image list, and further, the service server may acquire the hot virtual machine image list from the shared storage server based on the preset period. By hotspot virtual machine image is meant a virtual machine image that the service server will need to use.
In practical application, when the shared storage server marks the hot virtual machine image, the hot virtual machine image can be marked according to actual service, and various methods can be realized:
the first way is that in an educational scene, according to a resource planning table such as a class schedule, a virtual machine image which needs to be used the next day can be estimated. Such virtual machine images that are to be taken into use may be marked as hot virtual machine images.
The second way is that the operation log is recorded every time the link clone is done based on the virtual machine image. Therefore, the virtual machine image with higher recent use frequency can be analyzed and marked as a hot virtual machine image based on the operation log.
It should be noted that the hot spot virtual machine image marking manner is only used for illustration, and is not used for limiting the hot spot virtual machine image marking manner of the present application.
In the embodiment of the application, the service server can acquire the hot virtual machine image list from the service server by actively sending the hot virtual machine image list query request to the shared storage server; for example, the shared storage server wants the shared storage server to send the query request based on a preset period, or wants the shared storage server to send the query request based on an acquisition instruction triggered by a user.
Certainly, the sharing server may also actively push the hot virtual machine image list to each service server based on a preset rule, for example, when the hot virtual machine image list is updated once, the updated hot virtual machine image list is pushed to each service server.
Step 210: and determining a target hot spot virtual machine image which is not stored locally based on the locally stored virtual machine image and the hot spot virtual machine image list.
Specifically, after acquiring the hot virtual machine image list, the service server needs to determine which hot virtual machines in the hot virtual machine image list are not locally stored, specifically, if the service server does not locally store any virtual machine image, it is determined that each hot virtual machine in the hot virtual machine image list is not a target hot virtual machine image which is not locally stored, and at this time, all hot virtual machine images included in the hot virtual machine image list need to be acquired from the shared storage server.
For example, the hot virtual machine image list includes a virtual machine image 1, a virtual machine image 2, and a virtual machine image 3, and if the service server does not locally store a virtual machine image, it is determined that the virtual machine image 1, the virtual machine image 2, and the virtual machine image 3 are all target hot virtual machine images, and the virtual machine image 1, the virtual machine image 2, and the virtual machine image 3 need to be acquired from the shared storage server. If the service server locally stores the virtual machine image 1, the virtual machine image 2 is determined, and the virtual machine image 3 is the target hotspot virtual machine image, at this time, only the virtual machine image 2 and the virtual machine image 3 need to be acquired from the shared storage server.
Further, in the embodiment of the present application, the hot virtual machine image list includes a hot virtual machine image name and summary information of a hot virtual machine image;
then, when determining a target hot virtual machine image that is not locally stored based on a locally stored virtual machine image and the hot virtual machine image list, a preferred implementation manner is:
traversing the hot virtual machine image list, and judging whether a virtual machine image with the same name as that of each hot virtual machine image exists locally or not aiming at each hot virtual machine image included in the hot virtual machine image list;
if the hot virtual machine image does not exist, determining that the hot virtual machine image is a target hot virtual machine image which is not stored locally;
if the target hotspot virtual machine image exists, judging whether the summary information of the locally stored virtual machine image is the same as the summary information of the hotspot virtual machine image, and if not, determining that the hotspot virtual machine image is the target hotspot virtual machine image which is not locally stored.
For example, the service server performs traversal statistics on the hot virtual machine image list, and checks whether an image with the same name as that in the hot virtual machine image list exists in the local storage of the server. If the virtual machine image with the same name exists, the MD5 value of the local existing virtual machine image of the server is calculated. And comparing the MD5 value of the local virtual machine image of the server with the MD5 value corresponding to the hot virtual machine image in the hot virtual machine image list. If MD5 is the same, it indicates that the latest version of the hot virtual machine image already exists locally and does not need to be downloaded. If the values of MD5 are different, it indicates that there is an update to the hot virtual machine image in the shared storage server, and the virtual machine image local to the overlay server needs to be downloaded.
Further, the service server may also determine and delete a locally stored virtual machine image that does not belong to the hotspot virtual machine image based on the hotspot virtual machine image list.
That is to say, a part of the virtual machine images stored locally by the service server is no longer the hot virtual machine images in the latest hot virtual machine image list, and at this time, due to the limitation of storage resources, such virtual machine images can be deleted, so as to avoid that too many virtual machine images are cached locally by the service server, thereby improving the utilization rate of the storage resources.
Step 220: and sending a target hotspot virtual machine image acquisition request to the shared storage server so as to acquire the target hotspot virtual machine image from the shared storage server.
In the embodiment of the application, when determining that the target hotspot virtual machine image which is not stored locally in the hotspot virtual machine image list is determined by the service server, the service server needs to acquire the target hotspot virtual machine image from the shared storage server, and specifically, the service server sends an acquisition request to the shared storage server to download and cache the target hotspot virtual machine image from the shared storage server to the local service server.
Step 230: and receiving a target cloud desktop starting instruction, and if the required target virtual machine image is determined to belong to the hot virtual machine image based on the target cloud desktop starting instruction, performing batch cloud desktop starting operation based on the target virtual machine image.
That is to say, on the premise that all the hot virtual machine images included in the hot virtual machine image list are cached locally in the service server, if the service server receives a target cloud desktop start instruction, it is determined whether the target virtual machine image required for starting the target cloud desktop is one of the current hot virtual machine images based on the target cloud desktop start instruction, and if so, batch fast cloning is directly performed according to the target virtual machine cached locally in the server, and the batch cloud desktop starting is completed.
Further, if it is determined that the required target virtual machine image does not belong to the hot virtual machine image based on the target cloud desktop startup instruction, sending a target virtual machine image acquisition request to the shared storage server to acquire the target virtual machine image from the shared storage server, and performing a batch cloud desktop startup operation based on the target virtual machine image.
That is to say, the target virtual machine image required for starting the cloud desktop at this time is not one of the current hotspot virtual machine images, that is, the target virtual machine image is not cached locally by the service server, then, the target virtual machine image needs to be acquired from the shared storage server first, and after the target virtual machine image is acquired, a batch cloud desktop starting operation is performed based on the target virtual machine image.
Based on the same inventive concept as the above method embodiment applied to a service server, for example, referring to fig. 3, a detailed flowchart of another cloud desktop booting method provided in the embodiment of the present application is shown, where the method is applied to a shared storage server in a cluster, the shared storage server stores virtual machine images corresponding to multiple types of services, the cluster further includes multiple service servers in communication connection with the shared storage server, and the method includes the following steps:
step 300: and marking the hot spot virtual machine mirror image corresponding to the hot spot service based on a preset rule, and generating a corresponding hot spot virtual machine mirror image list.
Step 310: receiving a hot spot virtual machine image list query request sent by a service server, and sending the hot spot virtual machine image list to the service server, so that the service server determines a target hot spot virtual machine image which is not locally stored based on a locally stored virtual machine image and the hot spot virtual machine image list.
