Background Art

[0002] As the market demand for cloud platforms grows, domestic cloud platforms are developing rapidly, are easier to use, and have better after-sales service guarantees, which are attracting more and more VMware platform (virtualization platform) users to start choosing these domestic cloud platforms. When the cloud platform is replaced, it is necessary to migrate the virtual machine resources on the original VMware system to the new cloud platform. However, in the actual migration scenario, most of the customer's original virtual machines are in use, and the migration time that can be reserved is limited. The hardware information of different customer cloud platforms is also different, and it is often impossible to provide customers with a relatively accurate migration time, which may result in insufficient estimated time or time waste.

[0053] The present application provides a method for measuring virtual machine migration time, comprising: traversing a preset IO pressure set to obtain a target IO pressure; injecting IO pressure into a source storage pool and a destination storage pool corresponding to a simulated virtual machine according to the target IO pressure, and starting a migration task for the simulated virtual machine; during the execution of the migration task, obtaining the read rate of the source storage pool, the write rate of the destination storage pool, and the transmission network bandwidth; obtaining the virtual machine migration time after the migration task is completed, and determining the average migration rate according to the migration data volume of the simulated virtual machine and the virtual machine migration time; recording the corresponding relationship between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth, and the average migration rate; when the preset IO pressure set is not completely traversed, returning to the step of traversing the preset IO pressure set to obtain the target IO pressure until the preset IO pressure set is completely traversed to obtain multiple groups of the corresponding relationships; determining the real corresponding relationship between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth, and the average migration rate according to all the corresponding relationships; and realizing the migration time measurement of the real virtual machine by using the real corresponding relationship.

At the same time, the average migration rate can also be calculated based on the migration data volume and migration time of the simulated virtual machine. Thus, the corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be recorded during each simulated virtual machine migration process, and the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be determined based on multiple groups of corresponding relationships, thereby realizing the migration time measurement of the real virtual machine. It can be seen that the technical solution obtains the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate by simulating the virtual machine migration task in the real scenario, which can be used to accurately measure the cross-cloud migration time of the virtual machine, while ensuring the successful migration of the virtual machine and reducing resource waste.

[0055] In one embodiment of the present application, since the average migration rate is calculated based on the migration data volume and migration time of the simulated virtual machine, the migration time refers to the time taken by the simulated virtual machine to migrate from the source cloud platform to the destination platform. Therefore, only when the migration task of the simulated virtual machine is successfully executed, the migration time taken is credible, and the accurate average migration rate can be further calculated. Therefore, after the migration task of the simulated virtual machine is completed, the corresponding migration result can be obtained to determine whether the migration task is successfully executed, and only the virtual machine migration time in the scenario where the migration task is successfully executed is retained, thereby ensuring the accuracy and credibility of the recorded virtual machine migration time, and further ensuring the accuracy of the average migration rate, which helps to build a more accurate correspondence between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate, and thus helps to achieve more accurate virtual machine migration time measurement.

[0056] The virtual machine migration time measurement device, electronic device, computer-readable storage medium and computer program product provided in this application also have the above-mentioned technical effects, and this application will not repeat them here.

[0062] The core of the present application is to provide a method for measuring the migration time of a virtual machine, which can accurately measure the time for virtual machine migration across clouds, thereby reducing resource waste while ensuring successful migration of the virtual machine; another core of the present application is to provide a device for measuring the migration time of a virtual machine, an electronic device, a computer-readable storage medium, and a computer program product, all of which have the above-mentioned beneficial effects.

[0063] In order to describe the technical solutions in the embodiments of the present application more clearly and completely, the technical solutions in the embodiments of the present application will be introduced below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0064] An embodiment of the present application provides a method for calculating virtual machine migration time.

[0065] Please refer to Figure 1 , Figure 1 This is a flow chart of a method for calculating virtual machine migration time provided in the present application. The method for calculating virtual machine migration time may include the following S101 to S108.

[0066] S101: Traverse the preset IO pressure set to obtain the target IO pressure.

[0067] This step aims to obtain the target IO pressure by traversing the preset IO pressure set, so as to use the target IO pressure to simulate the IO pressure injection scenario. The preset IO pressure set includes multiple IO pressure values, specifically multiple IO pressure values ​​within the preset IO pressure range. Each time the traversal operation of the preset IO pressure set is performed, a target IO pressure can be obtained for simulating the IO pressure injection scenario. Here, the traversal operation of the preset IO pressure set can be performed by sequential traversal.

[0068] S102: Inject IO pressure into the source storage pool and the destination storage pool corresponding to the simulated virtual machine according to the target IO pressure, and start the migration task of the simulated virtual machine.

[0069] This step aims to simulate the IO pressure injection scenario, that is, to inject IO pressure into the source storage pool and destination storage pool corresponding to the simulated virtual machine according to the target IO pressure, wherein the simulated virtual machine is the virtual machine to be migrated in the current IO pressure injection simulation scenario, the source storage pool is the storage pool of the source cloud platform where the simulated virtual machine is located, and the destination storage pool is the storage pool of the destination cloud platform where the simulated virtual machine needs to be migrated. Furthermore, during the IO pressure injection process, the migration task of the simulated virtual machine can be started to simulate the virtual machine migration task in the real scenario.

[0070] In one embodiment of the present application, injecting IO pressure into a source storage pool and a destination storage pool corresponding to a simulated virtual machine according to a target IO pressure, and starting a migration task for the simulated virtual machine may include:

[0071] According to the target IO pressure, IO pressure is injected into the source storage pool and the destination storage pool corresponding to the simulated virtual machine, and the IO pressure injection duration is counted;

[0072] When the IO pressure injection duration reaches the preset duration, the migration task of the simulated virtual machine is started.

[0073] In an embodiment of the present application, in the process of injecting IO pressure into the source storage pool and the destination storage pool corresponding to the simulated virtual machine according to the target IO pressure, before starting the migration task of the simulated virtual machine, the IO pressure injection duration can be monitored in real time, and the migration task of the simulated virtual machine can be started only when the IO pressure injection duration reaches the preset duration. It is understandable that in the early stage of injecting the target IO pressure into the source storage pool and the destination storage pool, since the system may be unstable due to the IO pressure just being injected into the system, immediately starting the migration task of the simulated virtual machine at this time may lead to the problem of simulated virtual machine migration failure, affecting the normal progress of the simulation experiment. Therefore, the migration task of the simulated virtual machine can be started after a certain period of IO pressure injection, so as to effectively ensure the successful execution of the simulated virtual machine migration task, and thus ensure the normal progress of the simulation experiment.

[0074] It should be noted that the specific value of the above-mentioned preset time length does not affect the implementation of the present technical solution, and can be set by technical personnel according to actual conditions, and this application does not limit this.

[0075] S103: During the execution of the migration task, the read rate of the source storage pool, the write rate of the destination storage pool, and the transmission network bandwidth are obtained.

[0076] This step aims to realize data collection during the execution of the simulated virtual machine migration task. The collection content may specifically include the read rate of the source storage pool, the write rate of the destination storage pool, and the transmission network bandwidth. The read rate of the source storage pool is the data reading rate of the source storage pool, the write rate of the destination storage pool is the data writing rate of the destination storage pool, and the transmission network bandwidth is the bandwidth of the transmission network between the source cloud platform and the destination cloud platform.

[0077] S104: After the migration task is completed, the virtual machine migration time is obtained, and an average migration rate is determined according to the migration data volume of the simulated virtual machine and the virtual machine migration time.

[0078] This step aims to calculate the average migration rate of the simulated virtual machine. First, after the migration task is completed, the virtual machine migration time can be obtained, that is, the time taken by the simulated virtual machine to migrate from the source cloud platform to the destination cloud platform; further, the average migration rate of the simulated virtual machine can be calculated in combination with the migration data volume of the simulated virtual machine. It can be understood that the migration data volume is the amount of virtual machine data that needs to be migrated in the simulated virtual machine, and the average migration rate is the quotient between the migration data volume and the virtual machine migration time.

[0079] In one embodiment of the present application, obtaining the virtual machine migration time after the migration task is completed may include:

[0080] After the migration task is completed, the execution result of the migration task is obtained;

[0081] If the execution result is that the migration task is successfully executed, the virtual machine migration time is obtained;

[0082] If the execution result is that the migration task fails, the process returns to the step of traversing the preset IO pressure set to obtain the target IO pressure.

[0083] The embodiment of the present application provides a method for obtaining the migration time of a virtual machine. It is understandable that since the average migration rate is calculated based on the amount of migration data and the migration time of the simulated virtual machine, the migration time refers to the time taken by the simulated virtual machine to migrate from the source cloud platform to the destination platform. Therefore, only when the migration task of the simulated virtual machine is successfully executed, the migration time taken is credible, and the accurate average migration rate can be further calculated. Therefore, after the migration task of the simulated virtual machine is completed, the corresponding migration result can be obtained to determine whether the migration task is successfully executed, and only the virtual machine migration time in the scenario where the migration task is successfully executed is retained, so as to ensure the accuracy and credibility of the recorded virtual machine migration time, and then ensure the accuracy of the average migration rate, which helps to build a more accurate real correspondence between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate, that is, it helps to achieve more accurate virtual machine migration time measurement.

[0084] If the execution result is that the migration task fails, returning to traverse the preset IO pressure set to obtain the target IO pressure step may include:

[0085] If the execution result is that the migration task fails, the error information is obtained;

[0086] If the error message does not contain IO pressure overload information, return to the step of traversing the preset IO pressure set to obtain the target IO pressure;

[0087] If the error message contains IO pressure overload information, the output prompt will be failed.

[0088] It is understandable that the various IO pressure values ​​in the preset IO pressure set are generally arranged in ascending order. If the reason for the failure of the simulated virtual machine migration task is IO pressure overload, then even if more different target IO pressures are switched, the simulated virtual machine migration task will continue to fail. Therefore, if the reason for the failure of the simulated virtual machine migration task is IO pressure overload, the experiment failure prompt information can be directly output to inform the technicians that this round of simulation experiment has failed and a new round of simulation experiment needs to be restarted. Of course, if the reason for the failure of the simulated virtual machine migration task is not IO pressure overload, continue to switch to the next target IO to continue the simulation experiment.

[0089] S105: Record the corresponding relationship between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth, and the average migration rate.

[0090] S106: When the preset IO pressure set is not completely traversed, return to the step of traversing the preset IO pressure set to obtain the target IO pressure, until the preset IO pressure set is completely traversed to obtain multiple sets of corresponding relationships.

[0091] It can be seen that, by using each target IO pressure in the preset IO pressure set, a set of corresponding relationships between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate can be obtained, that is, multiple sets of corresponding relationships between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate can be obtained. Obviously, the number of corresponding relationships should be less than or equal to the number of elements in the preset IO pressure set.

[0092] Wherein, when the preset IO pressure set is not completely traversed, the step of returning to traverse the preset IO pressure set to obtain the target IO pressure may include: when the preset IO pressure set is not completely traversed, clearing the source storage pool and the destination storage pool, and returning to traverse the preset IO pressure set to obtain the target IO pressure. That is, after each IO pressure injection simulation, the source storage pool and the destination storage pool may be cleared first to restore the two to the initial empty storage pool state, and then the next round of IO pressure injection simulation is started to effectively ensure that the test environment is not affected by irrelevant factors.

[0093] S107: Determine the actual corresponding relationship between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth, and the average migration rate according to all the corresponding relationships.

[0094] This step aims to determine the true correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate. The true correspondence can be calculated based on the correspondence between multiple groups of source storage pool read rates, destination storage pool write rates, transmission network bandwidth and the average migration rate obtained from the above simulation experiments.

[0095] Determining the actual correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth, and the average migration rate according to all the correspondences may include:

[0096] For each corresponding relationship, generate a pair of training samples corresponding to the corresponding relationship;

[0097] The preset machine learning algorithm is used to perform machine learning on all training sample pairs to obtain the true correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate.

[0098] The embodiment of the present application provides a method for determining the real correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate according to all the correspondences, that is, it can be implemented based on a training scheme of machine learning technology. Of course, this implementation method is only a preferred method provided by the embodiment of the present application, and it is not the only one. It can also be implemented by fitting calculation of multiple groups of correspondences, which will not be repeated in this application.

[0099] S108: Calculate the migration time of the real virtual machine using the real corresponding relationship.

[0100] In this step, after obtaining the real correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate based on S101 to S107, the real correspondence can be applied to the migration scenario of the real virtual machine to achieve the migration time measurement of the real virtual machine. It can be understood that the above S101 to S107 are experimental calculation processes for the real correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate. In actual application scenarios, it can be executed only once and the real correspondence can be saved, and it can be directly called in the migration scenario of the real virtual machine.

[0101] The method of calculating the migration time of a real virtual machine by using the real corresponding relationship may include:

[0102] Obtain the real read rate of the source storage pool, the real write rate of the destination storage pool, the real bandwidth of the transmission network, and the real migration data volume of the real virtual machine;

[0103] Determine the actual average migration rate corresponding to the actual read rate of the source storage pool, the actual write rate of the destination storage pool, and the actual bandwidth of the transmission network based on the actual corresponding relationship;

[0104] The actual migration time of the actual virtual machine is calculated based on the actual migration data volume and the actual average migration rate.

[0105] Specifically, when the real correspondence between the read rate of the source storage pool, the write rate of the destination storage pool, the transmission network bandwidth and the average migration rate is applied to the migration scenario of the real virtual machine, the real read rate of the source storage pool, the real write rate of the destination storage pool and the real bandwidth of the transmission network corresponding to the real virtual machine can be obtained, and the real migration data volume of the real virtual machine can be determined. Therefore, the migration time of the real virtual machine can be measured in combination with the above-mentioned real correspondence, and the real migration time of the real virtual machine can be obtained.

[0106] It can be seen that the method for calculating the virtual machine migration time provided in the embodiment of the present application performs IO pressure injection simulation on the source storage pool and the destination storage pool corresponding to the simulated virtual machine according to different IO pressure values, and executes the migration task of the simulated virtual machine during each IO pressure injection simulation process to obtain the source storage pool read rate, the destination storage pool write rate and the transmission network bandwidth during the simulated virtual machine migration process. At the same time, the average migration rate can also be calculated according to the migration data volume and migration time of the simulated virtual machine. Thus, the corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be recorded during each simulated virtual machine migration process, and the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be determined according to multiple groups of corresponding relationships, thereby realizing the migration time measurement of the real virtual machine. It can be seen that the technical solution obtains the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate by simulating the virtual machine migration task in the real scene, which can be used to accurately calculate the virtual machine cross-cloud migration time, while ensuring the successful migration of the virtual machine and reducing resource waste.

[0107] Based on the above embodiments:

[0108] In one embodiment of the present application, before traversing the preset IO pressure set and obtaining the target IO pressure, the following steps may also be included:

[0109] Obtaining pre-configuration information, including source cloud platform environment information, destination cloud platform environment information, source storage pool configuration information, destination storage pool configuration information, transmission network configuration information, and simulated virtual machine configuration information; the simulated virtual machine configuration information includes the amount of data to be migrated;

[0110] Determine the connectivity status between the source cloud platform and the destination cloud platform based on the source cloud platform environment information and the destination cloud platform environment information;

[0111] If the connection status is not connected, an error message will be output;

[0112] If the connection status is connected, the environment of the source cloud platform is initialized, and the source storage pool is determined in the source cloud platform according to the source storage pool configuration information;

[0113] Create a simulated virtual machine on the source storage pool according to the simulated virtual machine configuration information, and write virtual machine data into the simulated virtual machine according to the amount of migrated data;

[0114] Initialize the environment of the destination cloud platform and create a destination storage pool on the destination cloud platform according to the destination storage pool configuration information;

[0115] Set the transmission network type and transmission network bandwidth according to the transmission network configuration information.

[0116] The method for calculating the virtual machine migration time provided in the embodiment of the present application realizes the initial configuration of the source cloud platform and the destination platform, and the configuration content includes but is not limited to the cloud platform environment in the source cloud platform, the source storage pool, the simulated virtual machine to be migrated, the cloud platform environment in the destination cloud platform, the destination storage pool, the connection network between the source cloud platform and the destination cloud platform, etc. It should be noted that the simulation experiment can only be started when the connection network between the source cloud platform and the destination cloud platform can be connected normally, otherwise the simulation experiment will fail.

[0117] Based on the above embodiments, an embodiment of the present application provides another method for measuring virtual machine migration time.

[0118] Please refer to Figure 2 , Figure 2 A flowchart of another method for calculating virtual machine migration time provided in this application is as follows:

[0119] 1. Configuration phase:

[0122] (3) Set the storage pool type of the source storage pool on VMware and the destination storage pool on the destination cloud platform;

[0123] (4) Set the network type used during migration, which can support the setting of management network and data network;

[0124] (5) Set the range of IO injection to the source storage pool and the destination storage pool to: 0~N (the default is 0~30), which means the maximum amount of data injected into the storage pool is: storage pool storage capacity * N%.

[0126] (1) System startup to confirm environment information: Execute the command telnet iCenterIp 902 on the target cloud platform host iCenterHostIp to confirm whether the target cloud platform is connected to VMware. If not, an error message will be displayed to the user and the process will be terminated. If connected, continue to (2).

[0127] (2) Initialize the VMware environment, determine the VMware storage pool (source storage pool), record it as vCenterStorage, create a simulated virtual machine on the source storage pool, record it as vm1, and write D amount of data into vm1;

[0128] (3) Initialize the destination cloud platform environment and create a destination storage pool, recorded as iCenterStorage;

[0129] (4) Obtain the transmission network bandwidth and record it in Gigabit or 10 Gigabit.

[0130] 3. IO pressure injection:

[0131] (1) Inject IO pressure into the storage pool according to the preset IO pressure range. If not set, the storage pool will be injected with IO pressure of 0 to 30 by default. The meaning of the IO pressure range is as follows: 0 means no IO injection, and 1 means writing 1 / 100 of the total capacity of the storage pool into the storage pool every minute. By injecting IO pressure into the storage pool, the write rate of the destination storage pool and the read rate of the VMware storage pool are affected, so as to obtain the migration rate under different read and write rates.

[0132] (2) After each IO pressure injection, the read rate on the VMware side storage pool and the write rate on the destination cloud platform storage pool are detected respectively, which are recorded as Vread and Vwrite.

[0133] 4. Initiate the migration task:

[0134] (1) After the IO injection experiment is stable, initiate a virtual machine migration task on VMware and detect the task status during the migration process. When the task status is completed, record the task completion time. At this point, a set of data is acquired. If the task status is detected as failed, obtain the error message ERROR and determine whether the ERROR contains the information "Storage pool IO pressure is too high". If so, it indicates that the IO pressure has reached the migration limit and the migration task can no longer be performed normally. The experiment ends.

[0135] (2) Based on the data size D of the virtual machine and the task completion time t, the average migration rate v = D / t is calculated;

[0136] (3) Save the complete data (transmission network bandwidth, VMware-side storage pool read rate, destination cloud platform storage pool write rate). After multiple experiments, the overall data is shown in Table 1:

[0137] Table 1: Average migration rate records at different disk read and write rates

[0138]

[0139] (4) Use chaos engineering to inject IO into recovery and clear all data on the destination storage pool to restore the empty storage pool state, ensuring that the test environment is not affected by irrelevant factors.

[0140] 5. Data processing:

[0141] (1) After obtaining n sets of data, the data is trained through machine learning methods to obtain the true correspondence between the average VMware cross-cloud migration rate and the transmission network bandwidth, the VMware-side storage pool read rate, and the destination cloud platform storage pool write rate: V = β (Vnetwork, Vread, Vwrite);

[0142] (2) By obtaining Vnetwork, Vread, and Vwrite of the actual migration environment, the average migration rate V can be calculated. Based on the actual amount of virtual machine data Data and V that need to be migrated, the actual migration time can be calculated.

[0143] It can be seen that the method for calculating the virtual machine migration time provided in the embodiment of the present application performs IO pressure injection simulation on the source storage pool and the destination storage pool corresponding to the simulated virtual machine according to different IO pressure values, and executes the migration task of the simulated virtual machine during each IO pressure injection simulation process to obtain the source storage pool read rate, the destination storage pool write rate and the transmission network bandwidth during the simulated virtual machine migration process. At the same time, the average migration rate can also be calculated according to the migration data volume and migration time of the simulated virtual machine. Thus, the corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be recorded during each simulated virtual machine migration process, and the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be determined according to multiple groups of corresponding relationships, thereby realizing the migration time measurement of the real virtual machine. It can be seen that the technical solution obtains the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate by simulating the virtual machine migration task in the real scene, which can be used to accurately calculate the virtual machine cross-cloud migration time, while ensuring the successful migration of the virtual machine and reducing resource waste.

[0144] An embodiment of the present application provides a device for measuring virtual machine migration time.

[0145] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a virtual machine migration time measurement device provided by the present application. The virtual machine migration time measurement device is applied to a management service platform and may include:

[0146] A traversal module 1 is used to traverse a preset IO pressure set to obtain a target IO pressure;

[0147] Injection module 2, used to inject IO pressure into the source storage pool and the destination storage pool corresponding to the simulated virtual machine according to the target IO pressure, and start the migration task of the simulated virtual machine;

At the same time, the average migration rate can also be calculated according to the migration data volume and migration time of the simulated virtual machine. Thus, the corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be recorded in each simulated virtual machine migration process, and the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate can be determined according to multiple groups of corresponding relationships, thereby realizing the migration time measurement of the real virtual machine. It can be seen that the technical solution obtains the real corresponding relationship between the source storage pool read rate, the destination storage pool write rate, the transmission network bandwidth and the average migration rate by simulating the virtual machine migration task in the real scene, which can be used to accurately measure the virtual machine cross-cloud migration time, while ensuring the successful migration of the virtual machine and reducing resource waste.

[0158] The returning unit is used to return to the step of traversing the preset IO pressure set to obtain the target IO pressure if the execution result is that the migration task fails.

[0159] In one embodiment of the present application, the above-mentioned return unit can be specifically used to obtain error information if the execution result is that the migration task fails to execute; if the error information does not contain IO pressure overload information, return to the step of traversing the preset IO pressure set to obtain the target IO pressure; if the error information contains IO pressure overload information, output an experiment failure prompt.

[0160] In one embodiment of the present application, the device for calculating the virtual machine migration time may also include a configuration module, which is used to obtain pre-configuration information before traversing the preset IO pressure set and obtaining the target IO pressure. The pre-configuration information includes source cloud platform environment information, destination cloud platform environment information, source storage pool configuration information, destination storage pool configuration information, transmission network configuration information, and simulated virtual machine configuration information; the simulated virtual machine configuration information includes the amount of migration data; the connectivity status between the source cloud platform and the destination cloud platform is determined according to the source cloud platform environment information and the destination cloud platform environment information; if the connectivity status is not connected, an error prompt is output; if the connectivity status is connected, the source cloud platform environment is initialized, and the source storage pool is determined in the source cloud platform according to the source storage pool configuration information; a simulated virtual machine is created on the source storage pool according to the simulated virtual machine configuration information, and virtual machine data is written to the simulated virtual machine according to the amount of migration data; the destination cloud platform environment is initialized, and a destination storage pool is created on the destination cloud platform according to the destination storage pool configuration information; the transmission network type and the transmission network bandwidth are set according to the transmission network configuration information.
