In the following description, for purposes of illustration and description However, the art is known in the art. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the invention.

The following description will be made with reference to the accompanying drawings and specific embodiments. step.

Step S100: Pre-set a virtual machine disk according to the virtual machine template, and store it on a predetermined data storage carrier.

In step S100, the embodiment may specifically set a virtual machine disk according to attribute information of a storage resource occupied by the specified virtual machine in the virtual machine template, such as a virtual machine storage capacity specification. That is, the disk with the same storage capacity of the virtual machine in the virtual machine template is occupied in the resource pool in advance. Preferably, the preset virtual machine disk may be consistent with the storage capacity specification of the virtual machine template, and may further consider the storage capacity information occupied by the operating system and/or application specified (or loaded) in the virtual machine template. In other embodiments, the storage capacity information may also be randomly or periodically changed according to actual conditions, such as according to data storage. The storage capacity information of the virtual machine disk and the like are intelligently adjusted, such as the size of the actual remaining storage space of the carrier, which is not limited herein.

It should be noted that the data storage carrier of the present embodiment is a storage space for storing virtual machine disks, which may be one or more. Further, different data storage carriers may separately store different virtual machine templates. The obtained virtual machine disk may also store only the virtual machine disks pre-set by one type of virtual machine template in the same data storage carrier, and the specific settings may be different according to service conditions and work efficiency, and are not limited herein. . The virtual machine disk preset in this embodiment may be stored in the same data storage carrier as the virtual machine template (which may improve the efficiency of the preset process), or may be stored on a data storage carrier such as a local storage device of the cloud server (FIG. 1B). As shown in the above, the data storage carrier may be an external storage device, such as an IP SAN (IP-Storage Area Network), and an FC SAN. (Fibre Channel-Storage Area Network, Fibre Channel storage station i or network), NAS (Network Attached Storage), etc., are not limited herein.

The virtual machine template can be used as a template by using other virtual machines that have been used or serviced, or can be manually installed in advance. This embodiment describes a manual installation as an example: Create a virtual machine, specify the number of CPU cores, memory size, storage capacity, etc. of the virtual machine. After the creation, save the above information of the virtual machine and the virtual machine disk in the data storage carrier; The virtual machine installs the operating system and application software and stores it on the virtual machine disk, such as the WEB service and the database. After completing the above installation and installation process, it can be used as a subsequent preset virtual machine template according to the user's operation or intelligent judgment. .

Step S101: When the virtual machine needs to be distributed, the virtual machine disk is mounted on the virtual machine that is created immediately.

In step S101, the present embodiment may determine whether "the virtual machine needs to be issued" by using the interrupt request, or according to the service load condition of the cluster or the server, and when receiving the interrupt request or determining that the virtual machine needs to be issued, The virtual machine is created on the storage device of the cloud server, and the virtual machine disk that is set in step S100 is directly mounted to the virtual machine disk. Instantly created on a virtual machine.

It should be noted that, in the prior art, when a virtual machine needs to be distributed, the virtual machine needs to be set. The time is also related to the storage capacity of the virtual machine disk: The larger the storage capacity of the virtual machine disk, the longer it takes, and the slower the virtual machine is issued. It is not difficult to see that this embodiment advances the process of setting a virtual machine disk, and can be issued immediately when it needs to be issued. It should be pointed out that the "the process of setting the virtual machine disk in advance" mentioned in this embodiment may also receive an "interrupt request" for the virtual machine to be issued during the process of setting the virtual machine disk or according to the cluster. And the server's service load condition determines that "the virtual machine needs to be issued". At this time, the virtual machine disk being set up can be mounted and used for the service with the created virtual machine after completing the setting process, compared to the existing one. Technically, this approach still has the effect of speeding up the issuance of virtual machines.

The virtual machine that is released immediately can be distributed to the corresponding overloaded cluster or server for service according to the load of the cluster and the server, or can be distributed to the corresponding cluster and server for service according to the operation of the user. In the specific working process, processes such as associating networks are also included, and are not described in detail within the scope of those skilled in the art.

In addition, the virtual machine management method of the present embodiment can also perform instant setting (online setting) if there is no virtual machine disk set in advance in one or more data storage carriers when the virtual machine needs to be issued, so as to avoid virtuality that is not available immediately. The machine creates unnecessary troubles, and thus ensures that the virtual machine for service can be issued.

In summary, the present invention effectively solves the problem that in the prior art, when a virtual machine needs to be distributed, the virtual machine disk is set, and the process of setting the virtual machine disk requires a large amount of time, which may result in failure to timely issue the virtual machine. The invention improves the speed of issuing virtual machines, ensures work efficiency and work performance, and improves the user experience.

Referring to FIG. 2, which is a schematic flowchart of a second embodiment of a virtual machine management method according to the present invention, in step S200, a real-time quantity of a virtual machine disk in a data storage carrier is detected.

The difference from the previous embodiment is that the virtual machine management method of the embodiment needs to execute step S200 before performing the virtual disk of the virtual machine. For example, a certain number of pre-configured virtual machine disks may already exist in a given data storage carrier or in all available data storage carriers, the number of which may have reached and/or exceeded a certain range, or It may affect the working status and quality of service of the virtual machine being served due to the excessive number. It may also reduce the performance of the system due to unlimited presets. In addition, preset An excessive number of virtual machine disks may also result in wasted storage space of the data storage carrier. Therefore, in this embodiment, the real-time quantity of the virtual machine disks in one or more data storage carriers is detected by step S200 to be controlled according to the real-time quantity. , Switch to use the smart preset mode.

Step S201: Determine whether the real-time quantity is less than a preset threshold. When it is determined that the real-time quantity is less than (ie, "Yes") the preset threshold, step S202 is performed, and when it is determined that the real-time quantity is not less than (ie, "No") the preset threshold, step S203 is awaited.

The preset threshold may be set before step S200. The specific process may include: acquiring the number of virtual machines corresponding to the virtual machine template issued by the data storage carrier within a preset time; and setting a preset threshold according to the number of issuances. It is not difficult to see that in this embodiment, by setting a preset threshold value by acquiring the number of issuances in a preset time, the dynamic balance of the number of virtual machine disks in the data storage carrier can be realized, thereby ensuring that the preset time is always maintained. A virtual machine disk with a preset threshold is waiting for the process of mounting and issuing. In addition, the preset threshold can also be manually set, for example, according to the actual work and service needs, and is not limited herein.

Further, after the preset threshold is set, the preset mode can be automatically switched to be performed through the human interface interface or other intelligent modes (ie, step S200 is automatically executed).

Step S202, pre-setting a virtual machine disk according to the virtual machine template, and storing the virtual machine disk on a predetermined data storage carrier.

Step S203: When the virtual machine needs to be distributed, the virtual machine disk is mounted on the virtual machine that is created immediately.

Steps S202 and S203 of the present embodiment may refer to the descriptions of the foregoing embodiment with respect to step S100 and step S101, respectively, and are not described in detail within the scope of those skilled in the art.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a third embodiment of the virtual machine management method according to the present invention. The virtual machine management method of the present embodiment includes but is not limited to the following steps.

Step S300, detecting the real-time quantity of the virtual machine disks in the data storage carrier.

In step S300, a certain number of pre-set virtual machine disks may already exist in a specified data storage carrier or in all available data storage carriers, and the number may have reached and/or exceeded a certain range. Or it may affect the working status and quality of service of the virtual machine being served due to too many numbers, or it may be lowered due to unlimited presets. The operating performance of the system is low. In addition, pre-setting a large number of virtual machine disks may also waste the storage space of the data storage carrier. Therefore, the embodiment detects the virtual machines in one or more data storage carriers by step S300. The real-time number of disks to implement an intelligent pre-set mode.

Step S301: Determine whether the real-time quantity is less than a preset threshold. In the judgment that the real-time quantity is less than

(ie, "Yes") When the preset threshold is exceeded, step S302 is performed, and when it is determined that the real-time number is not less than (i.e., "No") the preset threshold, step S306 is awaited.

As described above, the preset threshold can be set by: obtaining the number of virtual machines issued by the data storage carrier corresponding to the virtual machine template within a preset time; and setting the preset threshold according to the number of issuances. It is not difficult to see that by setting the preset threshold value by obtaining the number of releases in the preset time, the dynamic balance of the number of virtual machine disks in the data storage carrier can be realized. In addition, the preset threshold can also be manually set, for example, according to actual work and service requirements, and is not limited herein.

Step S302: Determine whether the spatial residual value is less than a preset first remaining threshold. When it is determined that the remaining value of the space is not less than (ie, "No") the first remaining threshold, step S305 is performed, and when it is determined that the remaining value of the space is less than (ie, "Yes") the first remaining threshold, step S303 is performed. In other embodiments, the subsequent steps S303 and S304 may be omitted, and when it is determined that the spatial residual value is less than (ie, "Yes") the first remaining threshold, the process directly waits for step S306, and the embodiment only The detailed description of the various embodiments is not intended to limit the scope of the embodiments.

It should be noted that, in the case that it is determined that the real-time quantity is less than the preset threshold, it is required to further determine whether the spatial residual value of the remaining storage space of the data storage carrier is smaller than a preset first remaining threshold. Specifically, in step S302, in order to ensure the performance and service performance of the data storage carrier and the mounted virtual machine, etc., it is necessary to ensure an input/output port (ie, an I/O port) between the data storage carrier and the virtual machine. ) Smooth, or ensure that the data storage carrier has enough remaining storage space to store redundant data generated by the mounted virtual machine, or to expand and expand the mounted virtual machine (such as expanding the number of CPU cores, expanding the memory) Size, storage capacity, etc.) Therefore, in this embodiment, it is necessary to determine whether a virtual machine disk needs to be set in advance according to the size of the space residual value. It should be noted that the spatial residual value of the present embodiment may be the remaining storage space of one data storage carrier or the total storage space of multiple data storage carriers, for example, when the virtual machine disk needs to be preset to the data storage carrier A. When the remaining space of the remaining storage space of the data storage carrier A is smaller than the first remaining threshold, the virtual disk of the virtual machine is stopped to the data storage carrier A, and the remaining space of the remaining storage space of the data storage carrier B is not If it is smaller than the first remaining threshold, the virtual machine disk can be pre-set to the data storage carrier in the preset process.

Step S303: Determine whether the remaining value of the space is smaller than a preset second remaining threshold. When it is determined that the spatial residual value is less than (ie, "Yes") the second remaining threshold, step S304 is performed, and when it is determined that the spatial residual value is not less than (ie, "No") the second remaining threshold, step S306 is awaited Wherein the first remaining threshold is greater than (or greater than or equal to) the second remaining threshold.

Step S304, deleting at least one preset virtual machine disk.

It is not difficult to see that, in combination with the step S303 and the step S304, if the present embodiment has previously set the virtual machine disk according to the virtual machine template due to some special reasons (detecting real-time quantity error, or system poisoning, etc.), the virtual machine is preset in advance. The real-time quantity of the disk will be maliciously increased, and even the performance of the virtual machine that has been mounted for service may be seriously affected, or the data storage carrier for storing the virtual machine disk may be confusing, etc.; therefore, the present embodiment passes the step S303. In real time, it is determined whether the remaining value of the space remains in the state of being in a dynamic balance near the second remaining threshold, thereby avoiding the above problem and simultaneously cleaning out the redundant pre-set virtual machine disk. Further, in step S304, the virtual machine disk that has not been mounted for a certain period of time (such as one week, two weeks, or one month) may be cleared in time, such as a certain CPU core, memory size, Specifications such as storage capacity cannot be used for mounting services; of course, it can also be based on whether a certain type of virtual machine template is mounted at a low frequency, and it is judged that the spatial residual value is smaller than the preset second remaining wide. When the value is set, the virtual machine disk preset by this type of virtual machine template is deleted. The present embodiment can be cleaned up in step S304, so that a limited data storage carrier can be effectively used, and problems caused by a large number of virtual machine disks being set due to errors, poisoning, and the like can be prevented.

Step S305, pre-setting the virtual machine disk according to the virtual machine template, and storing it on a predetermined data storage carrier.

In step S305, In this embodiment, the virtual machine disk may be preset according to the attribute information of the storage resource occupied by the specified virtual machine in the virtual machine template, such as the virtual machine storage capacity specification. That is, the disk with the same storage capacity of the virtual machine in the virtual machine template is occupied in the resource pool in advance. Preferably, the preset virtual machine disk may be consistent with the storage capacity specification of the virtual machine template, and may further consider storage capacity information occupied by an operating system and/or an application specified (or loaded) in the virtual machine template. In other embodiments, the storage capacity information may be randomly or periodically changed according to actual conditions, for example, intelligently adjusting the storage capacity information of the virtual machine disk according to the actual remaining storage space of the data storage carrier, This is not limited here.

It should be noted that the data storage carrier of the present embodiment is a storage space for storing virtual machine disks, which may be one or more. Further, different data storage carriers may separately store different virtual machine templates. The obtained virtual machine disk may also store only the virtual machine disks pre-set by one type of virtual machine template in the same data storage carrier, and the specific settings may be different according to service conditions and work efficiency, and are not limited herein. . The virtual machine disk preset in this embodiment may be stored in the same data storage carrier as the virtual machine template (which may improve the efficiency of the preset process), or may be stored on a data storage carrier such as a storage device local to the cloud server; In other embodiments, the data storage carrier may also be an external storage device, which is not limited herein.

Step S306: When the virtual machine needs to be issued, the virtual machine disk is mounted on the virtual machine that is created immediately.

In step S306, the present embodiment may determine whether it is "need to issue a virtual machine" according to the service request of the cluster or the server, and when receiving the interrupt request or determining that the virtual machine needs to be issued, Then create a virtual machine (you do not need to create a virtual machine disk on the storage device of the cloud server according to the attribute information of the storage resource occupied by the virtual machine specified in the virtual machine template), and then directly mount the virtual machine disk obtained in step S305. Loaded on a virtual machine created on the fly.

It should be noted that, in the prior art, when a virtual machine needs to be distributed, the time required to set the virtual machine is specifically related to the storage capacity of the virtual machine disk, the type of the application and the operating system: The storage capacity of the virtual machine disk is larger. The more complex the type of application or operating system, the longer it takes, and the slower the virtual machine is issued. It is not difficult to see that this implementation The pre-set process is advanced in advance, and can be issued immediately when it needs to be issued. It should be pointed out that the "pre-set process" is performed in advance in the present embodiment. It is also possible to receive an "interrupt request" or a service according to the cluster or server in the process of pre-setting. According to the load situation, it is determined that the virtual machine needs to be issued. At this time, the virtual machine disk that is being set can be mounted with the created virtual machine after completing the setting process, compared with the prior art. There is still an effect of speeding up the issuance of virtual machines.

In a specific implementation process, step S306 may include the following process:

S1: Obtain the input specified data storage carrier and specified specification parameters when the virtual machine needs to be issued;

S2: searching for a corresponding data storage carrier according to the specified data storage carrier, and searching for a corresponding virtual machine disk in the corresponding data storage carrier according to the specified specification parameter;

S3: Obtain the virtual machine created in real time and mount the corresponding virtual machine disk to the virtual machine. It is not difficult to see from S1 to S3 that a system for services such as a cloud server is used for one or more clusters and servers for service at the same time, so users (administrators) need to specify different specifications in different data storage carriers in advance or in real time. The different virtual machine disks of the parameters are used for servicing within different clusters or servers. For example, in this embodiment, the virtual machine disk set by the required virtual machine template may be specified according to the service type of the cluster or the server, the network type, and the like. This embodiment implements the "search-match" optimization process through S1 to S3, which is more conducive to the optimization of work performance and service quality.

In addition, it should be noted that the prior art creates a virtual machine when the virtual machine needs to be issued, and then the virtual machine is mounted with the virtual machine disk of the virtual machine template, and is simultaneously created in another data storage carrier for saving and modifying. The differential disk of the data, that is to say, the virtual machine created by the prior art is simultaneously mounted on the virtual machine disk and the differential disk of the virtual machine template, and at the same time, data connection and transmission between the two storage carriers are required. In this way, the I/O ports of the two data storage carriers need to be occupied at the same time. If too many virtual machines are mounted at the same time or the I/O port is congested, the working efficiency and service of the issued virtual machines will be seriously affected. performance. In the embodiment, the virtual machine disk is pre-configured, and when the virtual machine disk is mounted on the virtual machine, the virtual machine only connects with the pre-set virtual machine disk to implement data connection and transmission, thereby ensuring the issuance. After the virtual machine's work efficiency and service performance.

The invention effectively solves the problem that the virtual device starts to be set when the virtual machine needs to be distributed in the prior art. The process of setting up a virtual machine disk requires a large amount of time, which may result in a technical problem that the virtual machine cannot be issued in time. The present invention avoids setting up the virtual machine when the virtual machine is issued, thereby effectively increasing the speed of issuing the virtual machine. It ensures work efficiency and work performance, and improves the user experience.

Referring to FIG. 4B, FIG. 4 is a schematic block diagram of a first embodiment of a cloud server according to the present invention. The cloud server of the present embodiment includes but is not limited to a preset module 41 and a distribution module 42.

The pre-setting module 41 is configured to pre-set the virtual machine disk according to the virtual machine template and store it on a predetermined data storage carrier.

As described above, the pre-setting module 41 of the present embodiment may specifically set a virtual machine disk according to attribute information of a storage resource occupied by the virtual machine specified in the virtual machine template, such as a virtual machine storage capacity specification. That is, the disk with the same storage capacity of the virtual machine in the virtual machine template is occupied in the resource pool in advance. Preferably, the pre-set virtual machine disk may be consistent with the storage capacity specification of the virtual machine template, and may further consider the storage capacity information occupied by the operating system and/or application specified (or loaded) in the virtual machine template. In other embodiments, the pre-setting module 41 may also set the storage capacity information randomly or according to a predetermined condition according to actual conditions, such as intelligently adjusting the storage of the virtual machine disk according to the size of the actual remaining storage space of the data storage carrier. Capacity information and the like are not limited herein.

It should be noted that the data storage carrier of the present embodiment is a storage space for storing virtual machine disks, which may be one or more. Further, different data storage carriers may separately store different virtual machine templates. The obtained virtual machine disk may also store only the virtual machine disks pre-set by one type of virtual machine template in the same data storage carrier, and the specific settings may be different according to service conditions and work efficiency, and are not limited herein. . The virtual machine disk preset in this embodiment may be stored in the same data storage carrier as the virtual machine template (which may improve the efficiency of the preset process), or may be stored on a data storage carrier such as a storage device local to the cloud server (FIG. 1B). The data storage carrier may be an external storage device, such as an IP SAN, an FC SAN, a NAS, etc., which is not limited herein.

The virtual machine template can use other virtual machines that have been used or used as templates, or can be manually installed in advance. This embodiment describes the manual installation as an example: Create a virtual machine, specify the CPU core, memory size, storage capacity, etc. of the virtual machine. After creation, The above information of the virtual machine and the virtual machine disk are saved in the data storage carrier; the operating system and application software are installed on the created virtual machine and stored on the virtual machine disk, such as the WEB service and the database; after completing the above installation and installation process, It can be used as a follow-up virtual machine template according to the user's operation or intelligent judgment.

The issuance module 42 is used to mount a virtual machine disk to an instant-created virtual machine when a virtual machine needs to be issued.

The issuing module 42 of the present embodiment may determine whether the virtual machine needs to be issued according to the service request of the cluster or the server, and when the interrupt request is received or the virtual machine needs to be issued, the issuing module 42 first Create a virtual machine (you do not need to create a virtual machine disk on the storage device of the cloud server according to the attribute information of the storage resource occupied by the virtual machine specified in the virtual machine template), and then directly mount the virtual machine disk set by the preset module 41. Go to the virtual machine created on the fly.

It should be noted that, in the prior art, when a virtual machine needs to be distributed, the time required for issuing the virtual machine is specifically related to the storage capacity of the virtual machine disk, the type of the application and the operating system: The storage capacity of the virtual machine disk is larger. The more complex the type of application or operating system, the longer it takes, and the slower the virtual machine is issued. It is not difficult to see that the pre-setting module 41 of the present embodiment advances the setting process, and the issuing module 42 can be issued immediately when it is required to be issued. It should be pointed out that the "pre-setting process" proposed by the pre-setting module 41 of the present embodiment may also receive an "interrupt request" for issuing a virtual machine in a preset process or according to a cluster, The service load of the server determines that "the virtual machine needs to be issued". At this time, the virtual machine disk that is being set in advance can be mounted with the created virtual machine after completing the setting process, compared with the prior art. This method still has the effect of speeding up the issuance of virtual machines.

In addition, the pre-setting module 41 of the present embodiment can also perform instant setting (online setting) if there is no virtual machine disk set in advance in one or more data storage carriers when the virtual machine needs to be issued, so as to avoid virtuality that is not available immediately. Unnecessary trouble during the machine, and further Ensure that virtual machines for service are available.

In summary, the cloud server of the present invention effectively solves the problem that the virtual machine disk is set up when the virtual machine needs to be distributed in the prior art, and the process of setting the virtual machine disk requires a large amount of time, which may result in the failure to timely issue the virtual machine. Technical Problem, the present invention pre-sets the same virtual machine disk as the virtual machine template, improves the speed of issuing the virtual machine, ensures the working efficiency and working performance of the cloud server, and improves the user experience.

Referring to FIG. 5, FIG. 5 is a schematic diagram of a second embodiment of a cloud server according to the present invention. The cloud server of the present embodiment includes but is not limited to a preset module 51, a distribution module 52, a detection module 53, a first determining module 54, and a second The judging module 55, the processing module 56 and the executing module 57.

As described above, the pre-setting module 51 is configured to pre-set the virtual machine disk according to the virtual machine template and store it on a predetermined data storage carrier.

The issue module 52 is used to mount a virtual machine disk to an instant-created virtual machine when a virtual machine needs to be issued.

It should be noted that, in this embodiment, the detecting module 53 is configured to detect the real-time quantity of the virtual machine disks in the data storage carrier. For example, a certain number of pre-configured virtual machine disks may already exist in a given data storage carrier or in all available data storage carriers, the number of which may have reached and/or exceeded a certain range, or It may affect the working status and quality of service of the virtual machine being served due to the excessive number. It may also reduce the performance of the system due to unlimited presets. In addition, pre-setting a large number of virtual machine disks may also result in The storage space of the data storage carrier is wasted. Therefore, the present embodiment detects the real-time number of virtual machine disks in one or more data storage carriers by the detection module 53 to implement an intelligent preset mode.

The first determining module 54 is configured to determine whether the real-time quantity detected by the detecting module 53 is less than a preset threshold. The preset threshold of the embodiment may be set according to the number of virtual machines issued by the data storage carrier within a preset time (or the frequency of issuance), thereby realizing the dynamic balance of the number of virtual machine disks in the data storage carrier. It also ensures that the virtual machine disk with the preset threshold value is always waiting to be mounted and issued within the preset time. In addition, the preset threshold can also be manually set, for example, according to the actual work and service needs, and is not limited herein. At this time, the executing module 57 is configured to notify the pre-setting module 51 to preset the virtual machine disk according to the virtual machine template when the first determining module 54 determines that the real-time quantity is less than the preset threshold, in the first sentence. When the breaking module 54 determines that the real-time number is not less than the preset threshold, the notification issuing module 52 mounts the virtual machine disk to the virtual machine that is created immediately when the virtual machine needs to be issued.

Further, the first determining module 54 of the embodiment may be further configured to determine whether a spatial residual value of a remaining storage space of the data storage carrier is less than a preset first remaining threshold. The first remaining threshold may be manually set or automatically set by the cloud server system, which is not limited herein. In this embodiment, in order to ensure the performance and service performance of the data storage carrier and the mounted virtual machine, it is necessary to ensure that the input/output ports (ie, I/O ports) between the data storage carrier and the virtual machine are unblocked, or data is guaranteed. The storage carrier has enough remaining storage space to store redundant data generated by the mounted virtual machine, or to expand and expand the mounted virtual machine (such as expanding the number of CPU cores, expanding the memory size and storage capacity, etc.) Therefore, in the embodiment, the first determining module 54 determines whether it is necessary to preset the virtual machine disk according to the size of the spatial residual value.

In addition, the space residual value of the embodiment may be the remaining storage space of one data storage carrier or the total storage space of the plurality of data storage carriers, for example, when the virtual machine disk needs to be preset to the data storage carrier A, the data If the spatial residual value of the remaining storage space of the storage carrier A is smaller than the first remaining threshold, then the virtual machine disk is preset to be stopped to the data storage carrier A, and the remaining space of the remaining storage space of the data storage carrier B is not less than the first For the remaining threshold, the virtual machine disk can be pre-set to the data storage carrier B in a preset process.

Correspondingly, the execution module 57 is specifically configured to notify the preset module 51 to preset the virtuality according to the virtual machine template when the first determining module 54 determines that the real-time quantity is less than the preset threshold and the spatial residual value is not less than the first remaining threshold. If the first judging module 54 determines that the real-time quantity is less than the preset threshold but the space residual value is less than the first remaining threshold, the notification issuing module 52 mounts the virtual machine disk to the instant creation when the virtual machine needs to be issued. On the virtual machine, when the first determining module 54 determines that the real-time number is not less than the preset threshold, the notification issuing module 52 mounts the virtual machine disk to the virtual machine that is created immediately when the virtual machine needs to be issued.

It is to be noted that the second determining module 55 of the present embodiment is configured to determine, after the first determining module 54 determines that the spatial residual value is less than the first remaining threshold, whether the spatial residual value is less than a preset second remaining threshold. The first remaining threshold is greater than the second remaining threshold.

It is not difficult to understand that there may be some special reasons in the cloud server system (detection module 53 detects the real-time quantity error, or the cloud server system poisoning, etc.), so that the virtual machine disk is always set according to the virtual machine template. At this time, the real-time quantity of the virtual machine disk is set to be maliciously increased, and even seriously affects the mounted service. The performance of the virtual machine, or the data of the data storage carrier used to store the virtual machine disk is confusing. Therefore, in this embodiment, the second judging module 55 determines in real time whether the spatial residual value is maintained in the vicinity of the second remaining threshold and is in a state of dynamic balance, thereby avoiding the above problem and simultaneously clearing out the redundant preset. Virtual machine disk.

The processing module 56 is configured to: when the second determining module 55 determines that the spatial residual value is less than the second remaining threshold, delete at least one preset virtual machine disk, and notify the issuing module 52 to hang the virtual machine disk when the virtual machine needs to be issued. When the second judging module 55 determines that the remaining value of the space is not less than the second remaining threshold, the notification issuing module 52 mounts the virtual machine disk to the virtual virtual machine when the virtual machine needs to be issued. on board.

As described above, the processing module 56 can clear the virtual machine disk that has been pre-set and stored for a certain period of time (such as one week or one month) and has not been mounted for use, such as a certain CPU core and memory. Specifications such as size and storage capacity cannot be used for mounting for monthly tasks. Of course, it is also possible to determine whether the space residual value is less than the preset value according to whether a certain type of virtual machine template is mounted at a low frequency. When the second remaining threshold is exceeded, the virtual machine disk preset by the virtual machine template of this type is deleted. The present embodiment enables a limited data storage carrier to be effectively used by intelligently deleting a pre-set virtual machine disk, and can prevent problems caused by a large number of virtual machine disks being set due to errors, poisoning, and the like.

Referring to FIG. 6 in conjunction with FIG. 5, in a preferred embodiment, the cloud server may further include an obtaining module 58 and a setting module 59.

The obtaining module 58 is configured to obtain the number of issued virtual machines corresponding to the virtual machine template issued by the data storage carrier within a preset time. In the embodiment, the method for setting the preset threshold by the obtaining module 58 to obtain the quantity of the preset time, the dynamic balance of the number of virtual machine disks in the data storage carrier can be realized, thereby ensuring that the preset time is always maintained. Pre-set a virtual machine disk waiting to perform the process of mounting and issuing.

The setting module 59 is configured to set a preset threshold according to the number of issuances acquired by the obtaining module 58. Referring to FIG. 7 in conjunction with FIG. 5, in a preferred embodiment, the issuing module 52 may specifically include The acquisition unit 520, the search unit 521, and the mount unit 522 are included.

The obtaining unit 520 is configured to obtain the input specified data storage carrier and the specified specification parameter when the virtual machine needs to be issued.

The searching unit 521 is configured to search for the corresponding data storage carrier according to the specified data storage carrier acquired by the obtaining unit 520, and search for the corresponding virtual machine disk in the corresponding data storage carrier according to the specified specification parameter acquired by the obtaining unit 520.

The mounting unit 522 is configured to acquire the virtual machine created in real time, and mount the corresponding virtual machine disk found by the searching unit 521 to the virtual machine.

In this embodiment, the cloud server may be used for serving in one or more clusters and servers at the same time, so the user (administrator) needs to specify different virtual machine disks with different specification parameters in different data storage carriers in advance or in real time. Used for services within different clusters or servers. For example, in this embodiment, the virtual machine disk set by the required virtual machine template may be specified according to the service type, network type, and the like of the cluster or the server. This embodiment achieves an optimized distribution process through "retrieval-match", which is more conducive to the optimization of work performance and service quality.

The present invention effectively solves the technical problem that the virtual machine disk is set in the prior art when the virtual machine needs to be distributed, and the process of setting the virtual machine disk requires a large amount of time, which may result in the failure to timely issue the virtual machine. The same virtual machine disk as the virtual machine template improves the speed of issuing virtual machines, ensuring work efficiency and performance, and improving the user experience.
