Example one

Fig. 1 is a flowchart of a virtual machine creating method according to an embodiment of the present invention, where the embodiment is applicable to a case where a virtual machine is created in a multi-computer-room scenario, and the method may be executed by a virtual machine creating apparatus, where the virtual machine creating apparatus may be implemented in a form of hardware and/or software, and the virtual machine creating apparatus may be configured in an electronic device. As shown in fig. 1, the method includes:

s110, receiving a virtual machine creating request, wherein the virtual machine creating request comprises: and target virtual machine resource information required by the current target virtual machine to be created.

The virtual machine may refer to a complete computer system which has complete hardware system functions and is simulated by software and runs in a completely isolated environment. For example, the virtual machine may be a VM, virtualBox, virtualPC, or the like. The target virtual machine may refer to a virtual machine currently to be created. The number of target virtual machines may be one or more. The target virtual machine resource information may include a hard disk memory size required for creating the target virtual machine, a running memory size required for running the target virtual machine, and a Central Processing Unit (CPU) core number.

Specifically, when a user wants to create a virtual machine, a virtual machine creation operation may be triggered on a user terminal, a virtual machine creation request is generated based on the virtual machine creation operation triggered by the user, and the virtual machine creation request is sent to the scheduling server; the dispatch server may be used to assign and create the target virtual machine to the room. The scheduling server may determine, based on the received virtual machine creation request, a size of a hard disk memory required to create the target virtual machine, a size of a running memory required when the target virtual machine runs, and a Central Processing Unit (CPU) core number.

And S120, traversing the plurality of machine rooms, and acquiring the available resource information of the current machine room corresponding to the current machine room traversed currently and the pre-allocated resource information of the current machine room.

The current machine room may refer to a machine room in which virtual machine creation task allocation is performed. The available resource information of the current computer room may refer to resource information available for creating a virtual machine in the current computer room. The available resources of the current computer room may be, but are not limited to, the size of the hard disk memory, the size of the operating memory, and the number of CPU cores available in the current computer room. The pre-allocation resource information of the current computer room may refer to resource information required for executing a virtual machine creation task allocated to the current computer room. The information of the pre-allocated resources of the current computer room can be, but is not limited to, the size of the hard disk memory of the current computer room, the size of the running memory and the number of the CPU cores required for executing the virtual machine creation task allocated to the current computer room.

Specifically, traversing a plurality of machine rooms, selecting one machine room as a current machine room, and acquiring available resource information of the current machine room corresponding to the current machine room traversed by the current machine room and pre-allocated resource information of the current machine room based on a machine room resource information traversal result. For example, a plurality of machine rooms are traversed, an idle machine room can be used as a current machine room, and available resource information of the current machine room corresponding to the current machine room traversed and pre-distributed resource information of the current machine room are obtained based on a machine room resource information traversal result. The current machine room available resource information can comprise a hard disk memory 100GB, an operating memory 16GB and a 32-core CPU. The information of pre-allocated resources of the current machine room can comprise a hard disk memory 50GB, an operation memory 8GB and a 16-core CPU.

Exemplarily, the "traversing multiple rooms" in S120 may include: determining a first machine room as a current machine room traversed for the first time; and if the fact that the residual resource information of the current machine room is smaller than the resource information of the target virtual machine is detected, based on a preset machine room sequence, taking the next machine room of the current machine room as the current machine room traversed next time.

The preset machine room sequence may be a sequence formed by preset machine room traversal sequences.

Specifically, in the process of traversing a plurality of machine rooms, a first machine room can be determined as a current machine room traversed for the first time, and available resource information of the current machine room corresponding to the current machine room traversed and pre-allocated resource information of the current machine room are obtained; and determining the residual resource information of the current machine room based on the available resource information of the current machine room corresponding to the current machine room and the pre-allocated resource information of the current machine room. Comparing the residual resource information of the current machine room with the resource information of the target virtual machine; if the fact that the residual resource information of the current machine room is smaller than the resource information of the target virtual machine is detected, and the fact that resources for creating the target virtual machine do not exist in the current machine room is indicated, based on a preset machine room sequence, the next machine room of the current machine room is used as the current machine room traversed next time, and the operations from S120 to S140 are repeated until the machine room which can be used for creating the target virtual machine is determined, so that machine rooms which can be distributed and used for creating the target virtual machine can be automatically selected from a plurality of machine rooms based on creating conditions, manual operation is avoided, and the distributing efficiency and the distributing accuracy of the target virtual machine are improved.

S130, determining the residual resource information of the current machine room corresponding to the current machine room based on the available resource information of the current machine room and the pre-distributed resource information of the current machine room.

The resource information of the current machine room may refer to resource information of the current machine room remaining after all tasks in the virtual machine creation queue are executed.

Specifically, the available resource information of the current machine room and the pre-allocated resource information of the current machine room are subtracted, and the remaining resource information of the current machine room corresponding to the current machine room is determined.

And S140, if the fact that the residual resource information of the current machine room is larger than or equal to the resource information of the target virtual machine is detected, the target virtual machine is allocated to the current machine room to be created.

Specifically, if it is detected that the remaining resource information of the current machine room is greater than or equal to the resource information of the target virtual machine, the target virtual machine is allocated to the current machine room for creation.

For example, the current available resource information of the machine room may include 100GB of a hard disk memory, 16GB of a running memory, and 32-core CPU; the pre-allocated resource information of the current machine room can comprise a hard disk memory 50GB, an operating memory 8GB and a 16-core CPU; through subtraction processing, the remaining resource information of the current machine room can be determined, and the remaining resource information can include a hard disk memory 50GB, an operating memory 8GB and a 16-core CPU. If the resource information of the target virtual machine can include 25GB of hard disk memory, 4GB of running memory and 8-core CPU, two target virtual machines can be allocated to the current machine room for creation.

It should be noted that Mi may be used to represent pre-allocation resource information of the ith machine room. There are n virtual machine creation tasks in the queue in the ith machine room. The resource information required by the jth virtual machine queued to be created in the ith computer room can be represented by Vij. The machine room pre-allocation resource information of the ith machine room can be identified as follows:

Mi＝∑Vij(1≤j≤n)

namely, the pre-allocation resource information of the machine room in the ith machine room is the sum of the resource information required by all the virtual machines waiting to be created in the ith machine room.

According to the technical scheme of the embodiment of the invention, the virtual machine creation request is received, and comprises the following steps: target virtual machine resource information required by a target virtual machine to be created currently; traversing a plurality of machine rooms, and acquiring current machine room available resource information and current machine room pre-allocation resource information corresponding to the current machine room traversed currently; determining the residual resource information of the current machine room corresponding to the current machine room based on the available resource information of the current machine room and the pre-distributed resource information of the current machine room; if the fact that the residual resource information of the current machine room is larger than or equal to the resource information of the target virtual machine is detected, the target virtual machine is allocated to the current machine room for creation, so that the machine rooms capable of allocating and creating the target virtual machine can be automatically selected from the multiple machine rooms based on the actually available resource information of the machine rooms, manual operation is avoided, the allocation efficiency and accuracy of the target virtual machine are improved, and the creation power of the virtual machine can be improved under the scene of multiple machine rooms.

On the basis of the technical scheme, the method further comprises the following steps: and if the last traversed current machine room residual resource information corresponding to the current machine room is smaller than the target virtual machine resource information, traversing the plurality of machine rooms again after a preset time interval until the machine room which meets the condition that the current machine room residual resource information is larger than or equal to the target virtual machine resource information is obtained.

Specifically, if the last traversed current machine room remaining resource information corresponding to the current machine room is less than the target virtual machine resource information, it is indicated that the current machine room is not allocated with the target virtual machine creation task, and after a preset time period, the multiple machine rooms need to be traversed again until the machine room meeting the condition that the current machine room remaining resource information is greater than or equal to the target virtual machine resource information is obtained, so that manual participation is not needed until all the target virtual machine creation tasks are completely allocated.

Example two

Fig. 2 is a flowchart of a virtual machine creating method according to a second embodiment of the present invention, where this embodiment describes in detail a process of determining remaining resource information of a current machine room corresponding to the current machine room based on available resource information of the current machine room and pre-allocated resource information of the current machine room on the basis of the above embodiment. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. As shown in fig. 2, the method includes:

s210, receiving a virtual machine creating request, wherein the virtual machine creating request comprises: and target virtual machine resource information required by the current target virtual machine to be created.

S220, traversing the plurality of machine rooms, and acquiring the available resource information of the current machine room corresponding to the current machine room traversed currently and the pre-allocated resource information of the current machine room.

For example, the current machine room available resource information may include 100GB of hard disk memory, 16GB of running memory, and 32-core CPU. The information of pre-allocated resources of the current machine room can comprise a hard disk memory 50GB, an operation memory 8GB and a 16-core CPU.

For example, the step S220 of "obtaining the available resource information of the current machine room corresponding to the current machine room traversed currently" may include: acquiring available resource information of a current physical machine corresponding to each physical machine in a current machine room traversed currently; and adding the current physical machine available resource information corresponding to all the physical machines to obtain the current machine room available resource information corresponding to the current machine room.

In particular, there may be at least one physical machine in each room. And acquiring the available resource information of the current physical machine corresponding to each physical machine in the current machine room traversed currently. For example, two physical machines with the same total resources exist in the current machine room; the information of the current available resource of the physical machine corresponding to the first physical machine may be, but is not limited to, 50GB of hard disk memory, 8GB of running memory, and 16-core CPU. The current available resource information of the physical machines corresponding to all the physical machines is added to obtain the current available resource information of the machine room corresponding to the current machine room, so that the current available resource information of the machine room corresponding to the current machine room can be determined based on each physical machine, the current available resource information of the machine room is prevented from being directly obtained, and the accuracy is improved. For example, the available resource information of the current machine room corresponding to the current machine room may be, but is not limited to, the hard disk memory 100GB, the operating memory 16GB, and the 32-core CPU.

For example, the step S220 of "obtaining the pre-allocated resource information of the current machine room corresponding to the current machine room traversed currently" may include: acquiring a virtual machine creation queue corresponding to a current machine room traversed currently, wherein the virtual machine creation queue comprises at least one virtual machine creation task; and adding the resource information required by the virtual machine creation in each virtual machine creation task to obtain the pre-distributed resource information of the current machine room corresponding to the current machine room.

The virtual machine creation queue may include a task that is performing a virtual machine creation operation and a task that is waiting to perform the virtual machine creation operation. After the task that is executing the virtual machine creation operation is executed, the available resource information of the current machine room corresponding to the current machine room can be updated.

In particular, there may be at least one physical machine in each room. And acquiring a virtual machine creation queue corresponding to the current machine room traversed currently. For example, two same virtual machines are created in the current machine room; the resource information required for creating the virtual machine in the first virtual machine creation task may be, but is not limited to, a hard disk memory 25GB, a running memory 4GB, and an 8-core CPU. The resource information required by the virtual machine creation in each virtual machine creation task is added to obtain the pre-allocation resource information of the current machine room corresponding to the current machine room, so that the pre-allocation resource information of the current machine room corresponding to the current machine room can be determined based on each physical machine, the pre-allocation resource information of the current machine room of the machine room is prevented from being directly obtained, and the accuracy is improved. For example, the information of the pre-allocated resources of the current machine room corresponding to the current machine room may be, but is not limited to, 50GB of hard disk memory, 8GB of running memory, and 16-core CPU.

S230, acquiring current machine room operation resource information required when the current machine room operates the non-virtual machine task; adding the pre-distributed resource information of the current machine room and the operating resource information of the current machine room, and subtracting the available resource information of the current machine room from the addition result to obtain the residual resource information of the current machine room corresponding to the current machine room.

The current machine room running resource information may be resource information required when the current machine room normally runs a non-virtual machine task. For example, the current machine room operation resource information may be, but is not limited to, an operation memory.

Specifically, each physical machine may need to run non-virtual machine tasks in addition to running virtual machines. In order to ensure that the physical machine can normally run virtual machine tasks and non-virtual machine tasks at the same time. The method can obtain the current machine room running resource information required when the current machine room runs the non-virtual machine task, such as 2GB of running memory; and adding the pre-allocated resource information of the current machine room and the operating resource information of the current machine room, and subtracting the available resource information of the current machine room from the addition result to obtain the residual resource information of the current machine room corresponding to the current machine room. For example, the remaining resource information of the current machine room corresponding to the current machine room may be, but is not limited to, 50GB, 6GB of running memory, and 16-core CPU.

And S240, if the detected residual resource information of the current machine room is greater than or equal to the resource information of the target virtual machine, allocating the target virtual machine to the current machine room for creation.

For example, the information of the pre-allocated resources of the current machine room may include a hard disk memory 50GB, an operating memory 8GB, and a 16-core CPU; the current machine room operation resource information comprises an operation memory 2GB; through addition processing, subtraction processing is carried out on the available resource information of the current machine room and the processing result, and the residual resource information of the current machine room corresponding to the current machine room can be obtained; the available resource information of the current machine room can comprise a hard disk memory 100GB, an operation memory 16GB and a 32-core CPU; the current machine room residual resource information can comprise a hard disk memory 50GB, an operation memory 6GB and a 16-core CPU; if the resource information of the target virtual machine may include 25GB of the hard disk memory, 4GB of the operating memory, and 8-core CPU, one target virtual machine may be allocated to the current machine room for creation, and the next machine room is used as the current machine room, and the operations from S220 to S240 are executed until all the virtual machine tasks are allocated to the machine room for creation.

According to the technical scheme of the embodiment of the invention, the information of the current machine room running resources required when the current machine room runs the non-virtual machine task is obtained; and adding the pre-allocated resource information of the current machine room and the operating resource information of the current machine room, and subtracting the available resource information of the current machine room from the addition result to obtain the residual resource information of the current machine room corresponding to the current machine room. If the residual resource information of the current machine room is detected to be larger than or equal to the resource information of the target virtual machine, the target virtual machine is allocated to the current machine room for creation, so that the non-virtual machine task can be operated in the physical machine while the normal operation of the virtual machine is ensured, the utilization rate of the physical machine is improved, the target virtual machine is reasonably allocated to the machine room, the allocation efficiency and accuracy of the target virtual machine are further improved, and the creation power of the virtual machine can be further improved in a multi-machine room scene.

In the context of the present invention, a computer-readable storage medium may be a tangible medium that can contain, or store a computer program for use by or in connection with an instruction execution system, apparatus, or device. A computer readable storage medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. Alternatively, the computer readable storage medium may be a machine readable signal medium. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) by which a user may provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic, speech, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a back-end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.

The computing system may include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical host and VPS service are overcome.

It should be understood that various forms of the flows shown above may be used, with steps reordered, added, or deleted. For example, the steps described in the present invention may be executed in parallel, sequentially, or in different orders, and are not limited herein as long as the desired results of the technical solution of the present invention can be achieved.

The above-described embodiments should not be construed as limiting the scope of the invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
