It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of a method for connecting a cloud desktop according to an embodiment of the present invention, where this embodiment is applicable to a situation that a cloud desktop needs to be connected for software access, and the method may be executed by a device connected to the cloud desktop, and specifically includes the following steps:
and S110, responding to a connection request of the cloud desktop instance, and preloading a snapshot file formed by the cloud desktop instance in virtual operation, wherein the snapshot file is used for storing hardware operation data and memory operation data of the cloud desktop instance.
Cloud desktops (also called desktop virtualization) are widely applied to various governments, enterprises and schools due to the advantages of information safety, convenience in maintenance, rapid deployment, low equipment replacement frequency and the like. Taking a teaching scene as an example, the cloud desktop example can be understood as teaching software and related operating environments thereof which need to be operated when students go to school.
In order to ensure that the cloud desktop instance can be quickly restored to the final running state when connected, a virtual machine is adopted to execute a complete running step on the cloud desktop instance, so that the complete running state of the cloud desktop instance in the virtual running process is saved as a corresponding snapshot file, and the snapshot file is used for storing hardware running data and memory running data of the cloud desktop instance. The hardware operation data may include: the state of a Central Processing Unit (CPU) of the computer, the memory of the display card, the state of hardware of the computer, and the like. The memory operation data may be: and when the user is connected with the cloud desktop through the browser, accessing the memory data required by the corresponding cloud desktop instance.
According to the method for connecting the cloud desktop, provided by the embodiment of the invention, the snapshot file is used for storing the complete running process of the cloud desktop instance, only an administrator needs to operate, and each user accessing the corresponding cloud desktop instance does not need to perform corresponding operation.
When a requester (such as a student) requests to connect to a certain cloud desktop instance, a connection request of the cloud desktop instance is generated and reported to a configuration end of the cloud desktop instance. Therefore, the configuration end responds to the connection request of the cloud desktop instance, and preloads the snapshot file formed by the corresponding cloud desktop instance in the virtual operation so as to obtain a hardware starting environment and a memory operation environment required by deploying the cloud desktop instance in the empty virtual machine in advance. The hardware starting environment represents the hardware running data contained in the snapshot file.
The preloading process may be reading a snapshot file pre-saved by the cloud desktop instance from a disk or a network disk, and loading the snapshot file into a memory of the physical machine. If the snapshot file is a compressed file, decompression can be performed in the process of loading the snapshot file into the memory of the physical machine, so that various snapshot data contained in the snapshot file are analyzed into the physical machine, and a requester has a connected hardware starting environment and a memory running environment when connecting a cloud desktop instance from the virtual machine.
It should be noted that the purpose of loading the snapshot file into the memory of the physical machine is as follows: and providing a hardware starting environment and a memory running environment required by the instance running for the empty virtual machine. A physical machine is a hardware system, such as a server or the like, that has physical devices relative to a null virtual machine.
And S120, running the created empty virtual machine instance by using the hardware running data and the memory running data in the snapshot file to generate a cloud desktop instance which is finished to run.
Since the snapshot file required in the virtual operation has been preloaded in step S110, the created empty virtual machine instance is directly operated, and the cloud desktop instance corresponding to the operation can be generated and operated.
In an alternative way, the way to run the created empty virtual machine instance may be: firstly, the created empty virtual machine instance is operated, so that the hardware operation data in the snapshot file can be loaded into the created empty virtual machine instance. At this time, the empty virtual machine instance in the current state does not contain memory operation data, and the cloud desktop instance can be quickly started. Then, in the operation process, memory operation data corresponding to the hardware operation data can be continuously loaded as required, so that a corresponding cloud desktop instance is automatically generated to be used for a plurality of requesters to perform cloud desktop instance connection.
According to the method for connecting the cloud desktop, provided by the embodiment of the invention, the virtual operation of the cloud desktop instance is made into the snapshot file, so that the hardware operation data and the memory operation data of the cloud desktop instance are stored in the snapshot file, when the requester connects the cloud desktop instance, the snapshot file pre-formed by the cloud desktop instance is directly preloaded, and the created empty virtual machine instance is operated by using the hardware operation data and the memory operation data in the snapshot file, so that the cloud desktop instance which is operated is generated. According to the scheme, when the cloud desktop instance which is completely operated is generated, the cloud desktop instance can be completely restored to the final operation state, a plurality of requesters do not need to operate again after being connected, the memory operation load of the cloud desktop instance is reduced, the problems that when a plurality of requesters operate the same cloud desktop instance at the same time, the operation load of the cloud desktop instance is too high, the operation time is too long are solved, the cloud desktop instance is quickly started, and the connection efficiency of the cloud desktop instance is improved.
Example two
The embodiment of the present invention is further optimized on the basis of the above embodiment, and the step of running the created empty virtual machine instance by using the hardware running data and the memory running data in the snapshot file is optimized, including: loading hardware running data in the snapshot file into the created empty virtual machine instance, and marking a memory address in the empty virtual machine instance as a missing state so as to run the empty virtual machine instance; and sequentially loading the memory operation data in the snapshot file into the empty virtual machine instance according to each missing memory address accessed by the empty virtual machine instance in the operation. The method has the advantages that the empty virtual machine instance performs targeted access to the memory operation data according to the missing memory address, a large amount of memory reading and writing cannot be generated, and the load of the server is reduced.
After the snapshot file formed by the cloud desktop instance in the virtual runtime is preloaded, the method further comprises the following steps: and analyzing the snapshot file, and separating and extracting hardware operation data and memory operation data in the snapshot file. The advantage of setting up like this is that can distinguish hardware operation data and memory operation data and handle, the analysis of being convenient for.
Further, before preloading the snapshot file formed by the cloud desktop instance at the virtual runtime, the method further comprises: in the virtual operation process of the cloud desktop instance, storing the complete operation data of the cloud desktop instance by adopting a thermal migration technology to obtain a snapshot file of the cloud desktop instance. The advantage of this arrangement is that the complete running data of the cloud desktop instance can be saved in the snapshot file, and the environment required for running the corresponding cloud desktop instance in real time when accessing the cloud desktop instance is not needed.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for connecting a cloud desktop according to a second embodiment of the present invention; specifically, the method comprises the following steps:
s210, in the virtual operation process of the cloud desktop instance, storing complete operation data of the cloud desktop instance by adopting a thermal migration technology to obtain a snapshot file of the cloud desktop instance.
The Live Migration is also called Live Migration or Live Migration, that is, when an empty Virtual Machine (Virtual Machine) is saved or restored, the running state of the entire empty Virtual Machine is usually saved completely, and meanwhile, the empty Virtual Machine can be quickly restored to an original hardware platform or even different hardware platforms. After recovery, the empty virtual machines still run smoothly, and the user does not perceive any difference. The empty virtual machine is an emulator of a computer system, simulates a complete computer system with complete hardware system functions and running in a completely isolated environment through software, and can provide functions of a physical computer.
S220, responding to the connection request of the cloud desktop instance, and preloading a snapshot file formed by the cloud desktop instance in virtual operation.
The snapshot file stores hardware running data and memory running data for the cloud desktop instance.
And S230, analyzing the snapshot file, and separating and extracting hardware operation data and memory operation data in the snapshot file.
And analyzing the snapshot data in the snapshot file, extracting and separating the hardware operation data and the memory operation data in the cloud desktop instance corresponding to the snapshot file, and caching the hardware operation data and the memory operation data in the cloud desktop instance corresponding to the snapshot file.
Generally, the memory operation data occupies more than 95% of the capacity of the whole snapshot data, for example, the total amount of the snapshot data is denoted as M, and the total amount of the memory data is denoted as N, which satisfy the following relation:
N≥0.95M
the volume of the hardware operation data occupying the snapshot data is less than or equal to 0.5, so that all the memory operation data cannot be loaded when the cloud desktop instance is started in the embodiment of the invention.
S240, loading the hardware running data in the snapshot file into the created empty virtual machine instance, and marking the memory address in the empty virtual machine instance as a missing state so as to run the empty virtual machine instance.
For an empty virtual machine instance created when a request is made to connect to a cloud desktop instance, hardware operation data contained in a snapshot file can be loaded into the created empty virtual machine instance, memory operation data is not loaded at first, and a memory address in the current empty virtual machine instance is marked as a missing state. Then, the empty virtual machine instance is operated, and at the moment, the empty virtual machine instance can be directly started according to hardware operation data, so that the starting efficiency of the cloud desktop instance is greatly improved.
Illustratively, in the process of running the null virtual machine instance, when snapshot data included in the snapshot file is loaded, if the speed of loading the data is v, the content of the whole snapshot data is loaded, and time is required
Where M represents the total amount of snapshot data.
However, in the embodiment of the present invention, the hardware operation data is loaded in the empty virtual machine instance first, and the loading time is equal to
N represents the total amount of memory data, so that the loading rate is increased by more than 20 times, and the starting efficiency of the cloud desktop instance is greatly improved.
And S250, sequentially loading the memory operation data in the snapshot file into the empty virtual machine instance according to each missing memory address accessed by the empty virtual machine instance in the operation process.
In the specific memory access process, access is carried out according to the memory addresses which are missing in the operation of the empty virtual machine instance, and the memory operation data of the memory addresses which are missing in the snapshot file are sequentially loaded to the empty virtual machine instance, so that the process of loading the memory data as required is realized, all the memory data corresponding to the snapshot file do not need to be loaded at one time, the carrying load of a server is reduced, and the loading rate is increased.
An alternative scheme is that memory operation data in a snapshot file is sequentially loaded into an empty virtual machine instance according to each missing memory address accessed by the empty virtual machine instance in the operation, and the method includes:
a) and generating a corresponding page missing request when the missing memory address is accessed every time in the operation of the empty virtual machine instance, wherein the page missing request carries the missing memory address accessed this time.
When the hardware operation data occupying a small amount of snapshot data is loaded into the empty virtual machine instance, but the hardware operation data does not contain the corresponding memory operation data, all memory addresses in the empty virtual machine instance can be marked as missing. Therefore, the empty virtual machine instance state can be set to be the running state, and after the running, a user can see the image of the desktop screen by connecting the cloud desktop instance.
However, since there is no memory operation data in the empty virtual machine instance, when the empty virtual machine instance accesses the missing memory address in operation, a corresponding page missing request is generated, and the corresponding memory operation data can be accessed according to the page missing request.
Optionally, each time the empty virtual machine instance accesses a missing memory address once in operation, a corresponding page missing request is generated, and the page missing requests of the embodiments of the present application may be sequentially generated according to the requirements of the cloud desktop instance, so that a process of loading memory operation data as required by carrying the missing memory address accessed this time according to the page missing request is realized, and the loading rate of the memory data is increased.
b) And responding to the page missing request, controlling the empty virtual machine instance to be switched from the running state to the standby state so as to load memory running data corresponding to the missed memory address accessed at this time in the snapshot file into the empty virtual machine instance, controlling the empty virtual machine instance to be switched back to the running state from the standby state after the loading is completed, and continuously accessing the rest memory addresses in the running of the empty virtual machine instance until the empty virtual machine instance is completely run.
When a page missing request is responded, the empty virtual machine instance needs to load corresponding memory running data from the snapshot file according to the missing memory address, the process controls the empty virtual machine instance to be switched from a running state to a standby state, and then the memory running data corresponding to the missing memory address accessed at this time in the snapshot file is loaded into the empty virtual machine instance in the standby state. And then after the loading is finished, controlling the empty virtual machine instance to be switched from the standby state to the running state again so as to enable the empty virtual machine instance to run normally according to the currently loaded memory running data. In the current process, the empty virtual machine instance is started from the snapshot file without the processes of starting up the operating system and running corresponding software, so that a large amount of memory reading and writing can not be generated when the empty virtual machine instance starts running, and the loaded data volume is small. And repeatedly executing the steps until all the memory operation data required by the operation of the cloud desktop instance are loaded.
And S260, generating a cloud desktop instance which is operated.
Optionally, the number of created empty virtual machine instances is the same as the number of requesters requesting to connect to the cloud desktop instance, that is, the number of requesters requesting to connect to the cloud desktop instance is estimated, and then a corresponding number of empty virtual machine instances are created. Taking a teaching scene as an example, if 30 students need to connect with a cloud desktop instance, 30 empty virtual machine instances need to be established, when the students access the cloud desktop instance, the students only need to load corresponding memory data files according to the missing memory addresses corresponding to each empty virtual machine instance, and the completion process of starting the cloud desktop, downloading courseware, running teaching software and importing courseware is not needed, so that the access time is saved.
On the basis of the above embodiment, the embodiment of the present invention is further optimized, and after the cloud desktop instance that has completed running is generated, the method further includes: and configuring the cloud desktop instance which is completed to run on a requester which requests to connect with the cloud desktop instance.
The cloud desktop instance which is completely operated is configured on the requesting party, so that the direct application of the final cloud desktop instance environment can be realized, the process that each user operates the required software in real time after starting the cloud desktop is not needed, the loading time is saved, and the use experience of the user is improved.
In the method for connecting the cloud desktop, which is provided by the embodiment of the invention, by taking a teaching scene as an example, an administrator only needs to make a cloud desktop instance of an experimental environment into a snapshot file in advance, and then the cloud desktop instance is copied by using the snapshot file, so that the final operation environment is obtained when students are connected to a remote desktop. The read-write operation of the external storage device is greatly reduced through the preloading technology, the time is shortened from several minutes to within 1 second through the quick starting technology, and the teaching efficiency is greatly improved.
