[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] In an exemplary embodiment, Figure 1 As shown, a method for executing a hot migration task is provided. This embodiment uses the method applied to a target cloud platform as an example. The target cloud platform is composed of computer equipment. Specifically, the target cloud platform can be composed of multiple servers or a terminal and a server. It can be understood that when the target cloud platform is composed of multiple servers or a terminal and a server, the method is implemented through the interaction of multiple servers or the interaction of a terminal and a server. In this embodiment, the method includes the following steps:

[0057] S201, obtaining a hot migration request, the hot migration request carrying a hot migration task indicating to migrate a target virtual machine in a first host device to a second host device, the first host device and the second host device both being host devices in a target cloud platform.

[0058] Among them, hot migration is also called online migration, which can migrate the target virtual machine between different host devices under the premise of ensuring the normal operation of the services carried by the target virtual machine. Hot migration can be a dynamic migration that copies both the hard disk storage and memory of the target virtual machine, or it can be a dynamic migration that only copies the memory image of the target virtual machine. The target cloud platform is also called a cloud computing platform, which refers to a platform that can provide users with computing, network and storage services based on hardware resources and software resources.

[0059] Optionally, in this embodiment, the hot migration request can be triggered by the user. When the user has a need to migrate the virtual machine in the target cloud platform from one host device to another host device in a hot migration manner, the hot migration request can be triggered. The virtual machine to be migrated is the target virtual machine in the hot migration task carried by the hot migration request, the host device where the virtual machine to be migrated is currently located is the first host device in the hot migration task carried by the hot migration request, and the host device to which the virtual machine to be migrated is to be migrated is the second host device in the hot migration task carried by the hot migration request.

[0060] S202 , obtaining target attribute information, where the target attribute information includes attribute information of the first host device and attribute information of the second host device, and determining a hot migration speed according to the target attribute information and a data volume of the target virtual machine.

[0061] The attribute information of the first host device refers to information that can be used to describe the performance, configuration and usage of the first host device, and the attribute information of the second host device refers to information that can be used to describe the performance, configuration and usage of the second host device. The hot migration speed, also known as the hot migration bandwidth speed, refers to the rate at which the data of the target virtual machine is transmitted between the first host device and the second host device during the hot migration process.

[0062] Optionally, in this embodiment, after obtaining the hot migration request, the target attribute information can be determined according to the hot migration task carried by the hot migration request. As an optional implementation, since the hot migration request carries the hot migration task, and the hot migration task is used to indicate that the target virtual machine in the first host device is migrated to the second host device, the first host device, the second host device, and the target virtual machine can be determined according to the hot migration task. After determining the first host device, the second host device, and the target virtual machine, the attribute information of the first host device and the attribute information of the second host device can be obtained, and the attribute information of the first host device and the attribute information of the second host device can be determined as the target attribute information, and the data volume of the target virtual machine can be obtained.

[0063] It should be noted that, since the data of the target virtual machine in the first host device needs to be migrated to the second host device during hot migration, the hot migration speed during hot migration, that is, the hot migration speed, can be determined based on the target attribute information and the data volume of the target virtual machine. In this embodiment, as an optional implementation, the target attribute information and the data volume can be directly input into a pre-trained hot migration speed determination model to obtain the hot migration speed output by the hot migration speed determination model. The hot migration speed of the hot migration process can also be determined based on the target attribute information, and then the time consumed by the hot migration can be determined based on the data volume and the hot migration speed. It can be determined whether to adjust the hot migration speed based on the consumed time. If adjustment is required, the adjusted hot migration speed is determined as the hot migration speed actually used in the hot migration process. If no adjustment is required, the hot migration speed is directly determined.

[0064] S203, when the network information of the target cloud platform indicates that the target cloud platform has a storage network, determine the storage network as the hot migration network of the target cloud platform, and use the hot migration network to perform the hot migration task based on the hot migration speed.

[0065] The network information of the target cloud platform is also the network card network information, which refers to information used to characterize the network contained in the target cloud platform. The storage network refers to a network used to store, read and transmit data in the target cloud platform. The hot migration network refers to the network used to transmit the data of the target virtual machine during the hot migration process.

[0066] Optionally, in this embodiment, the network information of the target cloud platform generated when the target cloud platform is initialized can be first obtained from the database of the target cloud platform, and it can be determined whether there is a storage network in the target cloud platform based on the network information. As an optional implementation method, if there is a storage network in the target cloud platform, the storage network is determined as the hot migration network of the target cloud platform, and the hot migration task is performed at the hot migration speed using the hot migration network, that is, the data of the target virtual machine is transmitted at the hot migration speed through the storage network.

[0067] The above-mentioned hot migration task execution method, device, computer equipment, computer-readable storage medium and computer program product first obtain a hot migration request, in which the hot migration request carries a hot migration task indicating that the target virtual machine in the first host device is migrated to the second host device, and the first host device and the second host device both belong to host devices in the target cloud platform; then obtain target attribute information, the target attribute information includes attribute information of the first host device and attribute information of the second host device, and then determine the hot migration speed according to the target attribute information and the data volume of the target virtual machine. When determining the hot migration network, it is possible to first determine whether the target platform has a storage network according to the network information of the target cloud platform. If so, the storage network is determined as the hot migration network of the target cloud platform, and the hot migration task is executed based on the hot migration speed using the hot migration network, thereby avoiding the default use of the management network as the hot migration network in the prior art. Since the management network needs to assume multiple management functions, its network traffic is relatively complex, resulting in the hot migration task executed using the management network having low stability and success rate problems, thereby effectively improving the efficiency of hot migration.

[0068] In some scenarios, in addition to the situation where the target cloud platform has a storage network, there may also be a situation where the target cloud platform does not have a storage network. In this embodiment, the situation where the network information of the target cloud platform indicates that the target cloud platform does not have a storage network is explained in detail. In an exemplary embodiment, the above method also includes:

[0069] Step A: When the network information of the target cloud platform indicates that the target cloud platform does not have a storage network, the management network in the target cloud platform is determined as a hot migration network, and the hot migration task is performed based on the hot migration speed using the hot migration network.

[0070] Among them, the management network refers to a network used to implement management functions in the target cloud platform. Optionally, in this embodiment, after obtaining the network information of the target cloud platform, if the target cloud platform determined according to the network information of the target cloud platform does not have a storage network, the management network in the target cloud platform is determined as a hot migration network, and the hot migration network is used to perform the hot migration task at the hot migration speed, that is, the data of the target virtual machine is transmitted at the hot migration speed through the management network.

[0071] It should be noted that there are also business networks in the target cloud platform, such as Figure 2 As shown, Figure 2A first host device and a second host device in a target cloud platform are shown. The first host device is taken as an example for explanation. In the first host device, there are two virtual machines (VMs), of which the virtual machine to be migrated to the second host device is the target virtual machine. The first host device also includes a management network card, a business network card and a storage network card. The management network card is a network interface for connecting to a management network in the target cloud platform, the business network card is a network interface for connecting to a business network in the target cloud platform, and the storage network card is a network interface for connecting to a storage network in the target cloud platform. Figure 2 The case shown is where a storage network exists on the target cloud platform. When performing a hot migration task for the target virtual machine, the data of the target virtual machine can be transmitted through the storage network. If a storage network does not exist on the target cloud platform, the data of the target virtual machine is transmitted directly through the management network.

[0072] Furthermore, the hot migration time of the target virtual machine with the same computing specification in different hot migration networks is different, which can be seen as follows: Figure 3 As shown, in Figure 3 The figure shows the hot migration time of the target virtual machine with the same computing specifications in the management network and storage network. Figure 3 It can be seen that the hot migration of the target virtual machine of the same computing specification takes longer time under the management network, and takes shorter time under the storage network. The management network can be a Gigabit management network, and the storage network can be a 10 Gigabit storage network.

[0073] In this embodiment, when the network information of the target cloud platform indicates that the target cloud platform does not have a storage network, the management network in the target cloud platform is determined as the hot migration network, and the hot migration task is performed based on the hot migration speed using the hot migration network. When the target cloud platform does not have a storage network, the management network is also used to perform the hot migration task, thereby avoiding the problem of being unable to perform the hot migration task when the target cloud platform does not have a storage network, thereby improving the success rate of the hot migration task.

[0074] In this embodiment, the specific implementation process of determining the hot migration speed according to the target attribute information and the data volume of the target virtual machine will be described in detail. Figure 4 As shown, the above S202 includes:

[0075] S301, determining a maximum thermal migration speed according to target attribute information.

[0076] The maximum thermal migration rate refers to the maximum value of the thermal migration rate.

[0077] Optionally, in this embodiment, since hot migration is to migrate the target virtual machine from the first host device to the second host device, and the target attribute information is a type of information that can be used to describe the performance, configuration, and usage of the first host device and the second host device, the maximum migration speed of the hot migration can be determined according to the target attribute information. As an optional implementation, the target attribute information can be input into a pre-trained maximum hot migration speed determination model to obtain the maximum hot migration speed output by the maximum hot migration speed determination model.

[0078] S302: When the data volume of the target virtual machine is greater than or equal to a preset data volume threshold, determine the maximum hot migration speed as the hot migration speed.

[0079] Among them, the preset data volume threshold can be pre-set by technical personnel according to actual needs.

[0080] Optionally, in this embodiment, since other services are running in the first host device and the second host device during the hot migration process, if the maximum hot migration speed is directly used as the hot migration speed, it may cause an impact on other services. Therefore, the appropriate hot migration speed can be determined according to the data volume of the target virtual machine. As an optional implementation method, after determining the maximum hot migration speed of the hot migration according to the target attribute information, it can be determined whether the data volume of the target virtual machine is greater than or equal to the preset data volume threshold. If the data volume of the target virtual machine is greater than or equal to the preset data volume threshold, it can be determined that the amount of data required to be transmitted by the target virtual machine is large, and the time required for hot migration is long. If the maximum hot migration speed is not used, the target virtual machine may be suspended for too long. Therefore, the maximum hot migration speed can be determined as the hot migration speed to shorten the time required for hot migration. Although the service may still need to be temporarily suspended during the hot migration process, the time of suspension of service can be controlled within a relatively short range to minimize the impact on the business.

[0081] S303, when the data volume of the target virtual machine is less than the preset data volume threshold, the maximum hot migration speed is adjusted, and the adjusted maximum hot migration speed is determined as the hot migration speed, and the maximum hot migration speed is greater than the adjusted maximum hot migration speed.

[0082] In this embodiment, as an optional implementation, if the data volume of the target virtual machine is less than the preset data volume threshold, it can be determined that the data volume required to be transmitted by the target virtual machine is small, and the time required for hot migration is short. Therefore, the maximum hot migration speed can be adjusted to reduce the maximum hot migration speed to obtain the hot migration speed, while ensuring that the hot migration task can be completed, while reducing the impact on other services. As an optional implementation, the maximum hot migration speed after adjustment can be half of the maximum hot migration speed.

[0083] In this embodiment, the maximum hot migration speed is determined based on the target attribute information; when the data volume of the target virtual machine is greater than or equal to the preset data volume threshold, the maximum hot migration speed is determined as the hot migration speed; when the data volume of the target virtual machine is less than the preset data volume threshold, the maximum hot migration speed is adjusted and the maximum hot migration speed after the adjustment is determined as the hot migration speed. The maximum hot migration speed is greater than the maximum hot migration speed after the adjustment. The most suitable hot migration speed is determined based on the data volume of the target virtual machine. While ensuring the completion of the hot migration task, the impact on other services of the first host device and the second host device is reduced, thereby effectively improving the success rate and stability of the hot migration task.

[0084] In this embodiment, the specific implementation process of determining the maximum hot migration speed according to the target attribute information is described in detail. The target attribute information may include network card information and CPU information. Figure 5 As shown, the above S301 includes:

[0085] S401, determining a candidate hot migration speed according to network card information.

[0086] The network card information may be used to indicate the network performance of the first host device and the second host device. The CPU information may be used to indicate the performance and model of the CPU of the first host device and the second host device.

[0087] Optionally, in this embodiment, since the network card information can be used to indicate the network performance of the first host device and the second host device, the candidate hot migration speed can be determined based on the network card information. As an optional implementation, the data transmission rate of the first host device and the second host device can be determined based on the network card information, and the data transmission rate can be determined as the candidate hot migration speed. Since the second host device is used to receive data of the target virtual machine, the candidate hot migration speed can be determined based on the network card information of the second host device. As an optional implementation, the data transmission rate of the second host device can be determined as the candidate hot migration speed.

[0088] S402: When the CPU information indicates that there is no safety limit on the hot migration speed, determine the candidate hot migration speed as the maximum hot migration speed.

[0089] In this embodiment, since some models of CPUs have security restrictions on the data transmission rate of the host device, that is, there are security restrictions on the thermal migration speed, the maximum thermal migration speed can be determined based on the CPU information of the first host device and the second host device. As an optional implementation method, it can be determined based on the CPU information whether there are security restrictions on the CPUs of the first host device and the second host device. If not, the candidate thermal migration speed can be directly determined as the maximum thermal migration speed.

[0090] S403, when the CPU information indicates that there is a safety limit on the hot migration speed, determine whether the candidate hot migration speed is greater than the safe hot migration speed indicated by the safety limit, and determine the maximum hot migration speed according to the determination result.

[0091] In this embodiment, since some CPUs have safety restrictions on the hot migration speed, for example, the Haiguang C86 CPU has hardware-level restrictions on the hot migration function, which makes it have safety restrictions on the hot migration speed. Therefore, the maximum hot migration speed can be determined according to the safety restrictions. As an optional implementation method, the safe hot migration speed indicated by the safety restrictions can be determined first, and the maximum hot migration speed can be determined based on the safe hot migration speed and the candidate hot migration speeds.

[0092] In this embodiment, a candidate hot migration speed is determined based on the network card information; when the CPU information indicates that there is no safety restriction on the hot migration speed, the candidate hot migration speed is determined as the maximum hot migration speed; when the CPU information indicates that there is a safety restriction on the hot migration speed, it is determined whether the candidate hot migration speed is greater than the safe hot migration speed indicated by the safety restriction, and the maximum hot migration speed is determined based on the determination result. It is determined through the CPU information whether the CPUs of the first host device and the second host device have safety restrictions on hot migration to improve the accuracy of the determined maximum hot migration speed.

[0093] In this embodiment, the specific implementation process of determining the maximum thermal migration speed according to the determination result will be described in detail. Figure 6 As shown, the above S403 includes:

[0094] S501 , when the determination result indicates that the candidate thermal migration speed is greater than the safe thermal migration speed, determine the safe thermal migration speed as the maximum thermal migration speed.

[0095] In this embodiment, since the CPU information indicates that the CPUs of the first host device and the second host device have safety restrictions on the thermal migration speed, the candidate thermal migration speed cannot be directly determined as the maximum thermal migration speed, and the maximum thermal migration speed needs to be determined based on the safe thermal migration speed indicated by the safety restrictions and the candidate thermal migration speed. As an optional implementation, the safe thermal migration speed and the candidate thermal migration speed can be compared. When the candidate thermal migration speed is greater than the safe thermal migration speed, the safe thermal migration speed can be determined as the maximum thermal migration speed.

[0096] S502: When the determination result indicates that the candidate thermal migration speed is less than the safe thermal migration speed, determine the candidate thermal migration speed as the maximum thermal migration speed.

[0097] Optionally, in this embodiment, when the candidate thermal migration speed is less than the safe thermal migration speed, it can be determined that the candidate thermal migration speed meets the safety limit, and the maximum thermal migration speed can be determined based on the candidate thermal migration speed. As an optional implementation, the candidate thermal migration speed can be directly determined as the maximum thermal migration speed.

[0098] In this embodiment, when the determination result indicates that the candidate thermal migration speed is greater than the safe thermal migration speed, the safe thermal migration speed is determined as the maximum thermal migration speed. When the determination result indicates that the candidate thermal migration speed is less than the safe thermal migration speed, the candidate thermal migration speed is determined as the maximum thermal migration speed. The maximum thermal migration speed is determined by comparing the safe thermal migration speed with the candidate thermal migration speed, thereby improving the accuracy of the determined maximum thermal migration speed.

[0099] This embodiment will explain in detail the situation where the bandwidth information of the hot migration network on the target cloud platform changes. In an exemplary embodiment, Figure 7 As shown, the above method also includes:

[0100] S601, when the bandwidth information of the hot migration network of the target cloud platform changes, obtain the target bandwidth information after the hot migration network changes.

[0101] The bandwidth information may be used to indicate a maximum data transmission rate of the hot migration network.

[0102] Optionally, in this embodiment, when the network card device or network link of the hot migration network changes, it may cause the bandwidth information of the hot migration network to change. As an optional implementation method, when the bandwidth information of the hot migration network of the target cloud platform changes, that is, when the maximum data transmission rate of the hot migration network changes, the target bandwidth information after the hot migration network changes can be obtained.

[0103] S602: Update concurrent task information of the target cloud platform according to the target bandwidth information. The concurrent task information is used to indicate the number of hot migration tasks that can be executed in parallel on the target cloud platform.

[0104] Optionally, in this embodiment, when the target cloud platform is initialized, the concurrent task information can be determined according to the bandwidth information of the hot migration network of the target cloud platform, that is, the number of hot migration tasks that can be executed in parallel by the target cloud platform. When the bandwidth information of the hot migration network of the target cloud platform changes, that is, when the maximum data transmission rate of the hot migration network changes, the concurrent task information of the target cloud platform can be updated according to the changed target bandwidth information. As an optional implementation method, if the target bandwidth information is greater than the bandwidth information, the update processing may be an increase processing, that is, increasing the number of hot migration tasks that can be executed in parallel by the target cloud platform. If the target bandwidth information is less than the bandwidth information, the update processing may be a decrease processing, that is, reducing the number of hot migration tasks that can be executed in parallel by the target cloud platform.

[0105] In this embodiment, when the bandwidth information of the hot migration network of the target cloud platform changes, the target bandwidth information after the change of the hot migration network is obtained, and the concurrent task information of the target cloud platform is updated according to the target bandwidth information. Through the change of the bandwidth information of the hot migration network, the number of hot migration tasks that can be executed in parallel on the target cloud platform is adjusted to improve the execution efficiency of the hot migration tasks of the target cloud platform.

[0106] In an optional embodiment of the present application, after obtaining the hot migration request, the method further includes: determining whether the second host device meets the hot migration conditions of the hot migration task, and if so, executing the step of obtaining target attribute information, otherwise, rejecting the hot migration request.

[0107] In this embodiment, since the second host device needs to receive the data of the target virtual machine, it is necessary to determine whether it meets the hot migration conditions of the hot migration task. As an optional implementation method, the CPU architecture, model, memory information and storage pool information of the second host device can be obtained first, and based on this information, it is determined whether the destination host device meets the hot migration conditions of the hot migration task, that is, whether the model architecture of the second host device matches and whether there is excess space to store the target virtual machine. This is because hot migration only supports homogeneous hot migration.

[0108] In this embodiment, after obtaining the hot migration request, it is determined whether the second host device meets the hot migration conditions of the hot migration task. If so, the step of obtaining target attribute information is executed; otherwise, the hot migration request is rejected, which can effectively improve the success rate of the hot migration task.

[0109] In an optional embodiment of the present application, the method further includes: determining the concurrent task threshold of each host device according to the network card information, bandwidth information and CPU information of each host device in the target cloud platform, and the concurrent task threshold is used to indicate the number of hot migration tasks that can be executed simultaneously by each host device, so as to improve the success rate and stability of the hot migration task. As shown in Table 1, Table 1 shows some CPUs with safety restrictions and the concurrent task thresholds of the host devices containing these CPUs, and Table 1 includes the concurrent task threshold and the corresponding safe hot migration speed.

[0111]

[0112] In an optional embodiment of the present application, after obtaining the target attribute information, the method further includes: obtaining the first processor architecture of the target virtual machine and the second processor architecture of the second host device, and if the first processor architecture and the second processor architecture are the same, the hot migration network step can be determined, and if they are not the same, the hot migration request is rejected. It should be noted that the above method is applicable to the case where the target virtual machine has a 32-bit processor architecture.

[0113] In an optional embodiment of the present application, in addition to the above-mentioned method for improving the stability and success rate of the hot migration task, the method provided by the present application also sets relevant constraints during the execution of the hot migration task. For example, during the migration process, operations such as life cycle and hardware device management cannot be performed on the target virtual machine; power supply to the first host device and the second host device is ensured to avoid accidental power off or restart of the first host device and the second host device.
