[0001] The present invention relates to the field of computer technology, and in particular to a virtual machine allocation method, apparatus, electronic device and storage medium. Background Technology

[0002] With the rapid development of digitalization and information technology, live-streaming teaching has become a widely used teaching method. In existing technologies, users can conduct hands-on practice via cloud desktops during live streams. When a user terminal makes a practical request, it requests virtualization operations from physical machines in the computer room to create virtual machines. These virtual machines are then randomly assigned to various user terminals, establishing a communication connection between the virtual machines and the user terminals. Users can then remotely operate the cloud desktop for practical exercises.

[0003] However, in the process of realizing this invention, it was found that the prior art has at least the following technical problems: users only apply for virtualization operation when they need to perform practical operation, and the virtualization process of physical machine will increase the user's waiting time; in addition, the random allocation method is prone to network latency, which reduces the user's experience during the practical operation. Summary of the Invention

[0004] This invention provides a virtual machine allocation method, apparatus, electronic device, and storage medium to improve the user experience during operation.

[0005] According to one aspect of the present invention, a virtual machine allocation method is provided, comprising:

[0006] Obtain the operation request sent by the user terminal, and determine the user area information corresponding to the user terminal based on the operation request;

[0007] Based on the location information of the candidate physical data centers corresponding to each pre-built candidate virtual machine, and the user area information, the transmission distance between the user terminal and each of the candidate physical data centers is determined.

[0008] Based on the transmission distances, a target virtual machine is determined from the candidate virtual machines, and the target virtual machine is assigned to the user terminal so that the user terminal can establish a connection with the target virtual machine and conduct practical training.

[0009] According to another aspect of the present invention, a virtual machine allocation apparatus is provided, the apparatus comprising:

[0010] The practical operation request acquisition module is used to acquire practical operation requests sent by user terminals and determine the user area information corresponding to the user terminal based on the practical operation requests.

[0011] The transmission distance determination module is used to determine the transmission distance between the user terminal and each of the candidate physical data centers based on the data center location information of each pre-built candidate virtual machine and the user area information.

[0012] The target virtual machine determination module is used to determine the target virtual machine from the candidate virtual machines based on the transmission distance, and to assign the target virtual machine to the user terminal so that the user terminal can establish a connection with the target virtual machine and perform practical training.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0014] At least one processor; and

[0015] A memory communicatively connected to the at least one processor; wherein,

[0016] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the virtual machine allocation method according to any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the virtual machine allocation method according to any embodiment of the present invention.

[0018] The technical solution of this invention determines the user area information corresponding to the user terminal by obtaining the practical request, and determines the transmission distance between the user terminal and each candidate physical data center based on the data center location information of each pre-built candidate virtual machine and the user area information. Based on each transmission distance, a target virtual machine is determined from each candidate virtual machine, and the target virtual machine is assigned to the user terminal so that the user terminal can establish a connection with the target virtual machine and perform practical training.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "comprising" and "etc." and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0026] Figure 1 This is a flowchart illustrating a virtual machine allocation method according to an embodiment of the present invention. The method can be executed by a virtual machine allocation device, which can be implemented in hardware and / or software.

[0027] like Figure 1 As shown, the method in this embodiment may specifically include:

[0028] S110. Obtain the operation request sent by the user terminal, and determine the user area information corresponding to the user terminal based on the operation request.

[0029] In this embodiment, when a user needs to conduct practical training, they can send a practical training request to the server through their user terminal. After receiving the practical training request, the server can allocate a virtual machine to the user terminal based on the request to complete the practical training corresponding to the request. For example, a practical training request may include an operation request for hands-on training, such as a request for hands-on practice in Photoshop.

[0030] In practice, user area information refers to the location information of the area to which the user terminal belongs. The user area information corresponding to the user terminal can be determined by parsing the operation request, or the user area information of the user terminal can be obtained by sending a location acquisition request to the user terminal.

[0031] Optionally, the user area information includes the Internet Protocol (IP) address of the user terminal. Determining the user area information corresponding to the user terminal based on the operation request includes: parsing the operation request, determining the IP address of the user terminal based on the parsing result, and using the IP address as the user area information.

[0032] Specifically, by parsing the practice request, the network interconnection protocol address of the user terminal that sent the practice request can be determined, and the network interconnection protocol address can be identified as the user area information.

[0033] S120. Based on the location information of the candidate physical data centers corresponding to each pre-built candidate virtual machine, and the user area information, determine the transmission distance between the user terminal and each candidate physical data center.

[0034] In practice, alternative virtual machines can be pre-built on each alternative physical machine in the alternative physical data center. An alternative physical data center may include at least one alternative physical machine, and an alternative physical machine may build at least one alternative virtual machine.

[0035] In this embodiment, different candidate physical data centers can have different location information. The location information can be differentiated by geographical region, including at least one of North China, South China, East China, and Central China; it can also be differentiated by province or city, such as Beijing, Shanghai, or Shenzhen. Furthermore, the location information can be refined to make it more precise. For example, the location information could be Chaoyang District of Beijing, Haidian District of Beijing, etc.

[0036] In practical implementation, the transmission distance between the user terminal and each candidate physical data center can be determined based on the data center location information and the user's area information. The transmission distance can be the geographical distance between the user terminal's location and the locations of the candidate physical data centers; or it can be the network transmission distance between the user terminal and each candidate physical data center.

[0037] S130. Based on each transmission distance, the target virtual machine is determined from each candidate virtual machine, and the target virtual machine is assigned to the user terminal so that the user terminal can establish a connection with the target virtual machine and conduct practical training.

[0038] In this embodiment, the method for determining the target virtual machine from among the candidate virtual machines may include: randomly selecting a candidate virtual machine from the candidate physical data centers corresponding to the minimum transmission distance, and determining it as the target virtual machine.

[0039] In this embodiment, the specific implementation method for determining the target virtual machine from each candidate virtual machine based on each transmission distance further includes: sorting the transmission distances in ascending order, and determining whether the candidate physical data centers corresponding to the current transmission distance meet the preset conditions in the order of sorting from front to back. If the preset conditions are met, the candidate physical data center corresponding to the current transmission distance is determined as the target physical data center; and the target virtual machine is determined from the candidate virtual machines corresponding to the target physical data center.

[0040] Specifically, the transmission distances can be sorted in ascending order. The shorter the transmission distance, the faster the network communication speed and the lower the network latency between the user terminal and the candidate physical data center. Therefore, while meeting the preset conditions, the candidate physical data center with the shortest transmission distance can be selected as the target physical data center, and the target virtual machine can be determined from the candidate virtual machines in the target physical data center.

[0041] For example, the preset conditions may include: whether the candidate physical data centers corresponding to the current transmission distance include candidate virtual machines for completing the practical training corresponding to the practical request; the preset conditions may also include: whether there are candidate virtual machines in the candidate physical data centers corresponding to the current transmission distance whose working status is idle. This embodiment, by selecting the candidate physical data center with the shortest transmission distance among the candidate physical data centers that meet the preset conditions as the target physical data center, and determining the target virtual machine in the target physical data center, can ensure that the transmission distance between the target virtual machine and the user terminal is small, reducing network latency and improving the user's experience during practical training.

[0042] Optionally, determine whether the candidate physical data center corresponding to the current transmission distance meets the preset conditions, including: determining the working status of each candidate virtual machine in the candidate physical data center corresponding to the current transmission distance; if there is a candidate virtual machine whose working status is idle, then determine that the candidate physical data center corresponding to the current transmission distance meets the preset conditions.

[0043] Specifically, the working status of candidate virtual machines includes idle and busy states. An idle state indicates that the candidate virtual machine is currently unoccupied and available for allocation; a busy state indicates that the candidate virtual machine is currently occupied and cannot be allocated again. Therefore, among the candidate virtual machines in the candidate physical data centers corresponding to the current transmission distance, if there is a candidate virtual machine in an idle state, it means that there is an available candidate virtual machine in that data center, and the candidate physical data center corresponding to the current transmission distance meets the preset conditions. In this case, the candidate physical data center can be designated as the target physical data center, and the target virtual machine can be identified within that target physical data center. If there is no candidate virtual machine in an idle state, it means that all candidate virtual machines in that data center cannot be allocated again, and the candidate physical data center corresponding to the current transmission distance does not meet the preset conditions. The process continues until a target physical data center that meets the preset conditions is identified.

[0044] In this embodiment, the working status is used to determine whether the candidate physical data center meets the preset conditions, thereby ensuring that there are available candidate virtual machines in the target physical data center for allocation to user terminals, which helps to improve the allocation efficiency of virtual machines.

[0045] In practice, when assigning a target virtual machine to a user terminal, the virtual machine information of the target virtual machine can be determined and sent to the user terminal to complete the assignment operation. This virtual machine information includes the virtual machine name, identifier, and other details. Based on the received virtual machine information, the user terminal can establish a communication connection with the target virtual machine to complete the practical training corresponding to the requested operation.

[0046] In this embodiment, before obtaining the operation request sent by the user terminal, the process includes: sending virtualization requests to each candidate physical machine in each candidate physical data center to generate candidate virtual machines; constructing a candidate queue corresponding to each candidate physical data center and storing the virtual machine information of the candidate virtual machines corresponding to each candidate physical data center in the corresponding candidate queue; allocating the target virtual machine to the user terminal, including: obtaining the virtual machine information of the target virtual machine in the target queue corresponding to the target virtual machine; and sending the virtual machine information of the target virtual machine to the user terminal.

[0047] To ensure rapid and efficient allocation of virtual machines to user terminals upon receiving a practical operation request, virtualization requests can be sent to each of the alternative physical machines in each alternative physical data center before receiving the practical operation request from the user terminal. These virtualization requests are used to request alternative physical machines to be created.

[0048] In practice, upon receiving a virtualization request, each candidate physical machine can generate at least one candidate virtual machine based on its remaining resources. Furthermore, after generating the candidate virtual machines, each candidate physical machine can send the virtual machine information corresponding to each candidate virtual machine to the server; this information includes the virtual machine name, identifier, and other details. To store the virtual machine information of each candidate virtual machine, the server can generate different candidate queues based on the candidate physical data center to which each candidate virtual machine belongs, and store the virtual machine information of candidate virtual machines generated in the candidate physical data center into the corresponding candidate queue.

[0049] Furthermore, when allocating a target virtual machine to a user terminal, the virtual machine information of the target virtual machine can be obtained from the target queue corresponding to the target virtual machine; the virtual machine information of the target virtual machine is then sent to the user terminal. This embodiment, through various alternative queues, can quickly determine the virtual machine information of alternative virtual machines generated in different alternative physical data centers, accurately determine the virtual machine information of the target virtual machine, and complete the allocation operation of the target virtual machine.

[0050] Optionally, after obtaining the virtual machine information of the target virtual machine, the method further includes: deleting the virtual machine information of the target virtual machine from the target queue, and updating the target queue based on the deletion result.

[0051] The target queue is a queue used to store virtual machine information of the target virtual machine. In this embodiment, in order to avoid mistakenly reassigning an already assigned target virtual machine when allocating virtual machines to other user terminals, the virtual machine information of the target virtual machine in the target queue can be deleted after obtaining the virtual machine information of the target virtual machine, and the target queue can be updated, thereby improving the accuracy of allocating virtual machines to target users.

[0052] In this embodiment, the method further includes: detecting the number of virtual machines corresponding to each candidate physical data center; when the number of virtual machines is less than a preset threshold, sending an add request to each candidate physical machine in each candidate physical data center to generate a new virtual machine.

[0053] To prevent a shortage of available virtual machines (VMs) when receiving numerous simultaneous operation requests from user terminals, thus hindering timely allocation of VM resources to each user terminal, the number of currently unoccupied VMs in each alternative physical data center can be periodically or randomly checked. If the number of VMs is less than a preset threshold, it indicates a shortage of available VMs, and an add request can be sent to each alternative physical machine in each alternative physical data center to generate VMs as new VMs. If the number of VMs is greater than or less than the threshold, it indicates that the current reserve of available VMs is sufficient, and no new VMs are needed. This embodiment, by detecting the number of VMs, prevents the inability to allocate VM resources to user terminals in a timely manner when a large number of operation requests occur simultaneously, helping to complete the VM allocation operation promptly and reducing the waiting time for users during the physical machine virtualization process.
