[0025] The specific embodiments of the application have been shown and described in the above drawings and specification, and it is to be understood that the application is not limited to the above-described embodiments. Rather, it is to be understood that the application is capable of numerous arrangements and embodiments, and the above-described embodiments are merely illustrative of the principles of the application. DETAILED DESCRIPTION

[0026] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description is merely exemplary in nature and is not intended to limit the present application, as described, by any means. Rather, the exemplary embodiments are intended to explain the principles of the present application, as detailed in the appended claims.

[0027] At present, a large number of services are performed on a network, and the services can be executed by virtual machines in a cluster. When the services change, the computing capability and storage capability of the virtual machines need to be changed, which requires re-allocation of the number of computing units and the number of storage units occupied by the virtual machines. OpenStack is an open source cloud service management platform, which can perform the above-mentioned re-allocation of the computing units and the storage units, so as to meet the service requirements.

[0028] When the OpenStack performs the re-allocation at present, a new virtual machine is usually generated according to a target configuration required, and then the original virtual machine is deleted, so as to realize the re-allocation of the virtual machine. However, this re-allocation mode can cause problems such as failure to create a new virtual machine and low node utilization.

[0029] In view of the above technical problems, the inventors propose the following technical concept: generating a configuration change amount according to a target configuration specified by a user and a configuration of a current virtual machine, and merging the configuration change amount with the configuration of the current virtual machine to obtain a new virtual machine.

[0030] Figure 1 An application scenario diagram of a virtual machine configuration processing method provided by an embodiment of the present application is shown in FIG. 1. Figure 1 In the scenario, a user terminal 101 and a server 102 are included.

[0031] It can be understood that the structure shown in the embodiment of the present application does not constitute a specific limitation on the virtual machine configuration processing method. In another possible embodiment of the present application, the above-mentioned architecture can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangement, and the specific application scenario can be determined, which is not limited herein. Figure 1 The components shown can be implemented in hardware, software, or a combination of software and hardware.

[0032] In the implementation process, the user terminal 101 can include a computer, a server, a tablet, a mobile phone, a personal digital assistant (PDA), a notebook computer, and the like, which can input and send data, and in some possible cases, can also be used to receive data and output data.

[0033] The server 102 can be implemented by using one server or a cluster of multiple servers with stronger processing capability and higher security, and in possible cases, can also be replaced by a computer or a notebook computer with stronger computing capability.

[0034] The user terminal 101 is configured to receive an instruction of a user, and send a corresponding configuration change instruction to the server 102. The server 102 is configured to, after receiving the configuration change instruction, change a configuration of a target virtual machine corresponding to a target virtual machine identifier in the configuration change instruction to a target configuration according to the target virtual machine identifier and the target configuration, to obtain a new virtual machine.

[0035] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0036] Figure 2 A flowchart of a virtual machine configuration processing method provided by an embodiment of the present application is shown in the figure. The execution subject of the embodiment of the present application can be the server 102 in the figure, or a computer and / or a mobile phone, and the embodiment of the present application does not make a special limitation thereon. As shown in the figure, the method includes the following steps. Figure 1 Figure 2 The method includes the following steps.

[0037] S201: receiving a configuration change instruction sent by a user terminal, wherein the configuration change instruction includes a target virtual machine identifier and a target configuration.

[0038] In this step, the configuration change instruction can be sent in the form of a message, a character string, or the like, and can be obtained after the user performs a click operation, a key input operation, or the like on the user terminal. The target virtual machine can be a virtual machine whose configuration needs to be changed, or a virtual machine corresponding to the configuration change instruction. Correspondingly, the target virtual machine identifier can be at least one of a name, an address, a UUID (Universally Unique Identifier), or the like of the target virtual machine. The target configuration can be a number of computing units, a size of occupied memory, a size of occupied cache, or the like.

[0039] ​For example, the change configuration instruction includes "virtual machine: virtual machine A, target configuration: CPU 4RAM 1024", which indicates that the change configuration instruction is executed on "virtual machine A", and "virtual machine A" needs to occupy 4 CPU (Central Processing Unit) cores and a RAM (Random Access Memory) unit with a capacity of 1024 MB. For another example, the change configuration instruction includes "100.121.111.01, target configuration: CPU 5RAM 512", which indicates that the change configuration instruction is executed on the virtual machine with the address "100.121.111.01", and the virtual machine with the address "100.121.111.01" needs to occupy 5 CPU cores and a RAM unit with a capacity of 512 MB.

[0040] S202: Find the attribute information corresponding to the target virtual machine identifier, wherein the attribute information includes a node identifier and a current configuration.

[0041] In this step, the attribute information corresponding to the target virtual machine identifier can be obtained by searching the preset correspondence between virtual machine identifiers and attributes according to the target virtual machine identifier. The node identifier can be the node where the virtual machine is currently located, and the current configuration can be the number of CPU cores currently used, the amount of RAM occupied, etc.

[0042] The correspondence between the virtual machine identifier and the attribute can be stored in a table, key-value pair, or the like. The correspondence can be established when the virtual machine is created or updated when the virtual machine configuration is modified.

[0043] S203: Obtain the node configuration corresponding to the node identifier.

[0044] In this step, the node configuration of the node corresponding to the target virtual machine identifier can be obtained by searching the preset correspondence between node identifiers and node configurations.

[0045] The correspondence between the node identifier and the node configuration can be calibrated by a worker or automatically generated by a program after reading the node configurations of each node.

[0046] S204: If the node configuration is greater than or equal to the target configuration, determine the configuration change amount according to the target configuration and the current configuration.

[0047] In this step, the node configuration is greater than or equal to the target configuration, which means that each configuration parameter (CPU core number, RAM occupancy, memory size, cache size, etc.) in the node configuration is greater than or equal to the corresponding configuration parameter in the target configuration. The configuration change amount can be determined by subtracting the target configuration from the current configuration.

[0048] For example, if the node configuration is "CPU: 10, RAM: 1024" and the target configuration is "CPU: 4, RAM: 512", the number of CPU cores and the size of RAM of the node configuration are both greater than those of the target configuration. Embodiments of the present application do not specifically limit the size of each parameter in the node configuration and the target configuration.

[0049] S205: Create a new virtual machine according to the configuration change and the current configuration.

[0050] In this step, the virtual machine intermediate quantity can be generated according to whether the configuration change is positive or negative, and the new virtual machine can be obtained by combining the virtual machine intermediate quantity with the current configuration, or the parameter value of the configuration change can be directly removed from the current configuration to obtain the new virtual machine.

[0051] The UUID of the new virtual machine can be the same as the UUID of the original virtual machine. The modification of the current configuration can be performed after sending a prompt to the user terminal and receiving a confirmation instruction input by the user terminal according to the prompt.

[0052] In a possible implementation, this step can be performed by using a component in OpenStack.

[0053] As can be seen from the description of the above embodiments, the embodiments of the present application accept the configuration change instruction sent by the user terminal, find the attribute information of the virtual machine corresponding to the target virtual machine identifier in the configuration change instruction, obtain the configuration of the node from the node identifier in the attribute information, compare the configuration of the node with the target configuration in the configuration change instruction, determine whether the update of the configuration of the target virtual machine can be completed in the current node, calculate the configuration change in the case of being able to update, and create a new virtual machine from the configuration change and the current configuration of the virtual machine, thereby realizing the change of the configuration of the virtual machine in the same node and avoiding the problem that the creation of the new virtual machine fails in the related art because the sum of the target configuration required for creating the new virtual machine and the current configuration is greater than the node configuration. In addition, since the creation of the new virtual machine is completed in the original node, the configuration of the current node can be more fully utilized.

[0054] In a possible implementation, in the step S205, creating a new virtual machine according to the configuration change and the current configuration includes steps S205A1 and S205A2.

[0055] S205A1: If the configuration change is negative, remove the absolute value of the configuration change from the current configuration to obtain the new virtual machine.

[0056] In this step, the new configuration specification can be obtained by subtracting the absolute value of the configuration change from the current configuration, and the new configuration specification is used to replace the configuration specification of the original virtual machine.

[0057] For example, the configuration change is to reduce 2 CPU cores or "CPU: -2", and the number of CPU cores in the current configuration is reduced by 2 to obtain a new virtual machine. For another example, the configuration change is to reduce 1024 MB of RAM usage or "RAM: -1024", and the RAM usage in the current configuration of the virtual machine is reduced by 1024 MB to obtain a new virtual machine. For another example, the configuration change is "CPU: -2, RAM: -512", and the number of CPU cores in the current configuration is reduced by 2 and the RAM usage in the current configuration is reduced by 512 MB to obtain a new virtual machine.

[0058] In a possible implementation, before obtaining the new virtual machine, the user terminal can also be sent prompt information for confirming the changed configuration, and the confirmation information sent by the user terminal is received. After receiving the confirmation information, or after a preset time, it is defaulted that the confirmation information is received, the absolute value of the configuration change is removed from the current configuration to obtain a new virtual machine.

[0059] S205A2: If the configuration change is positive, a virtual machine intermediate quantity with a configuration value of the configuration change is created. The current configuration is increased by the configuration value of the virtual machine intermediate quantity to obtain a new virtual machine.

[0060] In this step, for example, the configuration change is to increase 3 CPU cores or "CPU: 3", a virtual machine intermediate quantity with 3 CPU cores is created, and the virtual machine intermediate quantity is added to the original current configuration to obtain a new virtual machine. For another example, the configuration change is to increase 2048 MB of RAM usage or "RAM: 2048", a virtual machine intermediate quantity with 2048 MB of RAM is created, and the virtual machine intermediate quantity is added to the current configuration to obtain a new virtual machine. For another example, the configuration change is "CPU: 5, RAM: 1024", a virtual machine intermediate quantity with 5 CPU cores and 1024 MB of RAM usage is created, and the virtual machine intermediate quantity is added to the current configuration to obtain a new virtual machine.

[0061] This step can also replace the resources allocated by the original virtual machine with the sum of the current configuration and the virtual machine intermediate quantity. In a possible implementation, similar to the description in step S2051 described above, adding the virtual machine intermediate quantity to the current configuration can also be performed after receiving the confirmation information.

[0062] From the description of the above embodiments, it can be known that, in the case that the configuration change value is a negative value, the absolute value of the configuration change value is directly subtracted from the current configuration to obtain a new virtual machine, and in the case that the configuration change value is a positive value, a virtual machine intermediate value with the configuration value being the configuration change value is added, and the virtual machine intermediate value is combined with the current configuration to obtain a new virtual machine, so that the updating of the virtual machine configuration under the same node is realized, the UUID of the original virtual machine does not need to be changed, and the utilization rate of the node operation capability is increased.

[0063] In a possible implementation, after the virtual machine intermediate value with the configuration value being the configuration change value is created in the step S2052, the method further includes:

[0064] S52A: deleting the virtual machine intermediate value in response to receiving the recovery instruction sent by the user terminal.

[0065] In this step, the recovery instruction can be obtained after the user performs a clicking or inputting operation or the like on the user terminal. The recovery instruction can include the target virtual machine identifier and the recovery instruction.

[0066] For example, the virtual machine intermediate value "CPU: 2, RAM: 1024" has been created, and then the recovery instruction sent by the user terminal is received, the virtual machine intermediate value is deleted, and the UUID of the original virtual machine is used as the UUID for subsequent use.

[0067] If the configuration change value obtained after the step S204 is a negative value, and the recovery instruction of the user is received after the configuration change value is obtained, no processing is performed. The original virtual machine is maintained as the virtual machine for subsequent use.

[0068] From the description of the above embodiments, it can be known that, in the case that the configuration change value is a negative value, the absolute value of the configuration change value is directly subtracted from the current configuration to obtain a new virtual machine, and in the case that the configuration change value is a positive value, a virtual machine intermediate value with the configuration value being the configuration change value is added, and the virtual machine intermediate value is combined with the current configuration to obtain a new virtual machine, so that the updating of the virtual machine configuration under the same node is realized, the UUID of the original virtual machine does not need to be changed, and the utilization rate of the node operation capability is increased.

[0069] In a possible implementation, in the step S204, the configuration change value is determined according to the target configuration and the current configuration, including steps S2041 and S2042.

[0070] S2041: subtracting the second parameter value from the first parameter value to obtain a parameter difference, wherein the first parameter value is a parameter value corresponding to a target class configuration parameter in the target configuration, the second parameter value is a parameter value corresponding to the target class configuration parameter in the current configuration, and the target class configuration parameter is any class configuration parameter.

[0071] In this step, the configuration parameters can be classified into multiple categories, for example, the CPU core number is classified into one category, the RAM occupancy is classified into one category, and there can be other categories, and the embodiments of the present application do not make specific limitations on the categories of the configuration parameters. In this step, the differences of the configuration parameters can be obtained by respectively calculating the differences of the configuration parameters of each category.

[0072] For example, the target configuration is "CPU: 5, RAM: 1024", and the current configuration is "CPU: 4, RAM: 512", then the configuration parameter of the type of CPU core number is subtracted to obtain the parameter difference of the type of CPU core number, which is 1, and the configuration parameter of the type of RAM occupancy is subtracted to obtain the parameter difference of the type of RAM occupancy, which is 512 MB. For another example, the target configuration is "CPU: 7, RAM: 2048", and the current configuration is "CPU: 5, RAM: 1024", then the configuration parameter of the type of CPU core number is subtracted to obtain the parameter difference of the type of CPU core number, which is 2, and the configuration parameter of the type of RAM occupancy is subtracted to obtain the parameter difference of the type of RAM occupancy, which is -1024 MB.

[0073] S2042: The parameter differences of the configuration parameters of each category are collectively determined as the configuration change amount.

[0074] In this step, for example, the parameter difference of the type of CPU core number is -2, and the parameter difference of the type of RAM occupancy is 512 MB, and then the obtained configuration change amount is "CPU: -2, RAM: 512". For another example, the parameter difference of the type of CPU core number is 3, and the parameter difference of the type of RAM occupancy is 0, and then the obtained configuration change amount is "CPU: 3". For another example, the parameter difference of the type of CPU core number is -4, and the parameter difference of the type of RAM occupancy is -1024 MB, and then the obtained configuration change amount is "CPU: -4, RAM: -1024".

[0075] As can be seen from the description of the above embodiments, the embodiments of the present application obtain the parameter differences corresponding to the configuration parameters of each category by respectively calculating the differences of the configuration parameters of each category, and collectively determine the parameter differences of the configuration parameters of each category as the configuration change amount, so as to facilitate subsequent creation of a new virtual machine according to the parameter differences of the configuration parameters of each category and the current configuration.

[0076] In a possible implementation, in the step S205, a new virtual machine is created according to the configuration change amount and the current configuration, including: S205B1, S205B2.

[0077] S205B1: If the parameter differences of the configuration parameters of each category are all negative values, then the parameter values in the current configuration and the parameter differences are summed to obtain the new virtual machine.

[0078] In this step, since the parameter difference of each type of configuration parameter is negative, the parameter value in the current configuration is summed with the parameter difference, which is actually to reduce the parameter value in the current configuration to obtain a new parameter value, and the virtual machine containing the new parameter value is taken as a new virtual machine.

[0079] In the process of summing the parameter value and the parameter difference, each type of configuration parameter can be summed respectively.

[0080] S205B2: If the parameter difference of any type of configuration parameter is positive, a virtual machine intermediate quantity is created according to the parameter difference of each type of configuration parameter. A new virtual machine is created according to the current configuration and the virtual machine intermediate quantity.

[0081] In this step, the process of creating the virtual machine intermediate quantity is similar to the process of step S205A2 described above. For example, the parameter difference of the CPU core number is 2, and the parameter difference of the RAM occupancy is 1024 MB, so the virtual machine intermediate quantity generated is "CPU: 2, RAM: 1024", and the numerical value of the parameter difference of each type of parameter is not limited in the embodiments of the present application. The nova-conductor component in OpenStack is used to create. In this step and the above steps, the process of creating a new virtual machine can be performed by using the nova-compute component of OpenStack.

[0082] As can be seen from the description of the above embodiments, in the case that the parameter difference of each type of configuration parameter is negative, the current configuration is directly reduced by the absolute value of the parameter difference, and in the case that the parameter difference is positive, a virtual machine intermediate quantity is first created and then a new virtual machine is created from the virtual machine intermediate quantity, so that the effects of facilitating subsequent rollback operation and increasing resource utilization of the node are achieved.

[0083] In a possible implementation, in the case that the parameter difference of any type of configuration parameter is positive, the current parameter corresponding to the parameter difference being negative can also be summed with the parameter difference to obtain a virtual machine to be changed, a virtual machine intermediate quantity corresponding to the parameter difference being positive is generated, and a new virtual machine is created according to the configuration parameter of the virtual machine to be changed and the virtual machine intermediate quantity. The way of creating a virtual machine is similar to the above embodiments, which will not be described here.

[0084] In a possible implementation, the process of creating a new virtual machine in the above steps can be modifying the configuration file corresponding to the target virtual machine identifier according to the configuration change amount, increasing or decreasing the configuration data written in the configuration file, or writing or deleting the configuration data in the configuration file. The configuration data can be associated CPU core, memory occupancy partition, etc.

[0085] In a possible implementation, the above-mentioned variable configuration instruction further comprises a user identifier, and the method further comprises: determining a user authority according to the user identifier, and if the user authority does not belong to an administrator authority, the above-mentioned step S202 and subsequent steps are not performed. The step of determining the user authority comprises: searching for a preset administrator identifier list according to the user identifier, if the user identifier belongs to the administrator identifier list, the user authority belongs to the administrator authority, otherwise, the user authority does not belong to the administrator authority.

[0086] In a possible implementation, after the step S204 of determining the configuration change amount according to the target configuration and the current configuration, the method further comprises:

[0087] S210: generating a configuration change confirmation request according to the configuration change amount.

[0088] In this step, the configuration change amount can be input into a preset request template to obtain the change confirmation request. The values in the configuration change amount can also be extracted, and the extracted values can be written into the preset request template to obtain the configuration change confirmation request.

[0089] The request template can be preset by a staff. The obtained configuration change confirmation request is, for example, "the configuration change amount is CPU: 1, RAM: 512, please confirm or execute rollback", "the configuration change amount is CPU core flavin increased by 1, RAM occupancy increased by 512, please confirm or execute rollback", and the like. The content of the configuration change confirmation request is not limited in the embodiments of the present application.

[0090] S211: sending the configuration change confirmation request to a user terminal.

[0091] In this step, the configuration change confirmation request can be sent in the format of a message or a string. The configuration change confirmation request can also be sent in the form of a short message, software information, or a small program.

[0092] S212: in response to receiving a confirmation instruction sent by the user terminal according to the change confirmation request, creating a new virtual machine according to the configuration change amount and the current configuration.

[0093] In this step, the confirmation instruction can be input by a user on the user terminal, or generated by the user terminal in response to the user's touch. The confirmation instruction can be a preset string. The process of creating a virtual machine is similar to that in the above-mentioned embodiments, and will not be described here.

[0094] From the description of the above embodiments, it can be known that, by generating the configuration change confirmation request after generating the configuration change amount, and sending the configuration change confirmation request to the user terminal, the embodiments of the present application realize prompting the user to confirm the configuration change, and after receiving the confirmation instruction of the user terminal, a new virtual machine is created according to the configuration change amount and the current configuration, which realizes providing the optional item of fallback before providing the new virtual machine, and facilitates the user to cancel the process before completely completing the creation of the new virtual machine.

[0095] In a possible implementation, after the node configuration corresponding to the node identifier is acquired in the step S203, the method further includes:

[0096] S220: if the node configuration is less than the target configuration, sending a node change request to the user terminal.

[0097] In this step, any parameter in the node configuration can be less than the configuration parameter corresponding to the target configuration, and the node change request is sent to the user terminal. The node change request can be a preset message or a string.

[0098] For example, the node configuration is "CPU: 5, RAM: 2048", and the target configuration is "CPU: 8, RAM: 1024", the number of CPU cores in the target configuration is greater than the number of CPU cores in the node configuration, and the node configuration is less than the target configuration. For another example, the node configuration is "CPU: 7, RAM: 1024", and the target configuration is "CPU: 6, RAM: 2048", the RAM occupancy in the target configuration is greater than the RAM occupancy in the node configuration, and the node configuration is less than the target configuration. For another example, the node configuration is "CPU: 3, RAM: 1024", and the target configuration is "CPU: 5, RAM: 2048", each configuration parameter in the target configuration is greater than the configuration parameter in the node configuration, and the node configuration is less than the target configuration. The node change request is, for example, "current node configuration is insufficient, please input the node change confirmation instruction to replace the node", and the content of the node change request is not limited in the embodiments of the present application.

[0099] S221: in response to receiving the node change confirmation instruction input by the user on the user terminal, acquiring the node configuration of the remaining node.

[0100] In this step, the node change confirmation instruction can also be received through a wired or wireless network. The node configuration of the remaining node can be obtained by reading the pre-stored node list, reading the node identifier in the node list, and finding the corresponding relationship between the node identifier and the node configuration according to the node identifier to obtain the node configuration of the remaining node. The remaining node can be another node other than the node corresponding to the node identifier, and can also be a node not occupied by the virtual machine.

[0101] If the remaining node is a node not occupied by a virtual machine, the node configuration can be obtained by reading an unoccupied node list of the node not occupied by the virtual machine, reading each node identifier in the unoccupied node list, finding a correspondence between the node identifier and the node configuration, and obtaining the node configuration of the remaining node. The unoccupied node list of the node not occupied by the virtual machine can be pre-written by a staff.

[0102] S222: If the node configuration of the target node is greater than or equal to the target configuration, create a virtual machine in the target node, where the target node is any node.

[0103] In this step, the node configuration of the target node is greater than or equal to the target configuration, which can be the opposite of the case in step S220 described above, and will not be described here. The virtual machine can be created in the target node with the target configuration, and at this time, the virtual machine does not need to be created according to the configuration change and the current configuration.

[0104] After the virtual machine is created in the target node, the virtual machine in the original node (i.e., the node corresponding to the node identifier in step S202) can also be deleted.

[0105] Figure 3 The overall flowchart of the virtual machine configuration processing method provided by the embodiment of the present application is shown in FIG. 1. Figure 3 As shown in FIG. 1, the overall flowchart includes:

[0106] S301: Obtain the current configuration of the original virtual machine.

[0107] In this step, the original virtual machine is the virtual machine corresponding to the target virtual machine identifier.

[0108] S302: Determine the configuration change according to the target configuration and the current configuration.

[0109] S303: If the configuration change is a negative value, send a configuration change confirmation request to the user terminal. If a node change confirmation instruction sent by the user terminal is received, execute step S305, and if a recovery instruction sent by the user terminal is received, do not make any changes.

[0110] S304: If the configuration change is a positive value, create a virtual machine intermediate quantity and send a configuration change confirmation request to the user terminal. If a node change confirmation instruction sent by the user terminal is received, execute step S306, and if a recovery instruction sent by the user terminal is received, execute step S307.

[0111] In steps S303 and S304, a positive value indicates that the overall flowchart is an incremental configuration of the virtual machine, and a negative value indicates that the overall flowchart is a decremental configuration of the virtual machine. The incremental configuration indicates an increase in the configuration of the virtual machine, and the decremental configuration indicates a decrease in the configuration of the virtual machine.

[0112] S305: creating a new virtual machine according to the configuration change amount and the current configuration.

[0113] In this step, the new virtual machine specification can replace the original virtual machine.

[0114] S306: adding the configuration value of the virtual machine intermediate amount to the current configuration to obtain a new virtual machine.

[0115] S307: deleting the virtual machine intermediate amount.
