In order to solve the technical problems, the embodiment of the invention provides the following general ideas:
the method comprises the steps of firstly obtaining a creating request, obtaining target metadata based on resource specification information as the creating request carries the resource specification information specified by a user, determining the type of a virtual machine with the target metadata, selecting target hardware aiming at the type of the virtual machine, then obtaining a configuration file matched with the target hardware, and finally creating the target virtual machine by using the configuration file and the target hardware.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
This embodiment provides a method for creating a virtual machine, where the method may run in an OS operating system in the form of a code, and the OS operating system may specifically be: windows operating system, DOS operating system, MAC operating system, etc., and the embodiment is not limited in particular.
The method for creating the virtual machine provided by the embodiment of the invention can be applied to a cloud computing management platform, and the cloud computing management platform can be an OpenStack framework: the OpenStack is an open source cloud computing management platform project, is a combination of a series of software open source projects, and can also adopt other similar architectures. As shown in fig. 1, the method comprises the steps of:
step S101: and acquiring a creating request, wherein the creating request carries the resource specification information specified by the user.
In a specific implementation process, after obtaining an input instruction of a user, the cloud computing management platform generates a creation request for creating a virtual machine, where the creation request carries resource specification information specified by the user, for example, the input instruction may be a specification of a CPU, a GPU, a RAM, and a hard disk resource, and the resource specification information specified by the user is obtained based on a resource specification selected by the user from a cloud host resource specification (browser). Specifically, the cloud computing management platform implemented in the present invention is a cloud platform that provides computing, networking, and storage capabilities based on hardware resources and software resource services.
In a specific embodiment, a User may input an instruction on a UI (User Interface) by way of mouse click, touch screen click, voice command issue, or keyboard input, so as to select a required hardware In a self-defined manner, for example, select two 10-core CPUs, two GPUs each having 20GB display, a 256GB RDIMM (Registered Dual In-line Memory Module) DDR4(The fourth generation synchronous dynamic random access Memory) type rdi (The resource generation double-data rate synchronous dynamic random access Memory), and a 960GB solid-state disk, where after The UI obtains The input instruction of The User, The UI generates a creation request for creating a virtual machine, carries resource specification information specified by The User, and selects corresponding resource specification information from The cloud host resource specification; on the other hand, the User may also input an instruction on a UI (User Interface) by clicking with a mouse, clicking with a touch screen, issuing a voice command, or inputting with a keyboard to select a classification recommended by the UI, for example, the UI displays hardware suitable for deep learning as an "deep learning class", displays hardware suitable for image classification as an "image classification class", displays hardware suitable for image recognition as an "image recognition class", and selects the "deep learning class" from these classifications, so that after acquiring the input instruction of the User, the UI generates a creation request for creating a virtual machine, and selects corresponding resource specification information from the cloud host resource specification.
Step S102: and acquiring target metadata based on the resource specification information.
In the specific implementation process, the cloud computing management platform has a large amount of metadata, and the metadata is used for describing attributes of the resource specification information and supporting functions such as indicating storage positions, historical data, resource searching, file recording and the like. After the cloud computing management platform obtains the resource specification information specified by the user, the cloud computing management platform can reversely obtain the target metadata from a large amount of metadata.
For example, after the cloud computing management platform acquires the resource specification information specified by the user, for example, the acquired resource specification information is: since the metadata has corresponding target metadata to describe the attributes of the resource specification information, the target metadata can be obtained through the resource specification information specified by the user, for example, hw, CPU _ policy ═ divided, aggregate _ instance _ extra _ tasks, pghs ═ true, avx512_ vnni, and hw, men _ page _ size ═ 1G.
Step S103: based on the target metadata, a virtual machine type is determined.
In the specific implementation process, the target metadata is identified, and the virtual machine type is determined to be a vCPU type virtual machine or a vGPU type virtual machine according to the identification result. More specifically, if the target metadata is identified to contain CPU metadata, RAM metadata and hard disk metadata at the same time, the virtual machine type is determined to be a vCPU type virtual machine, otherwise, the virtual machine type is determined to be a vGPU type virtual machine.
For example, the cloud computing management platform acquires target metadata, such as metadata of hw, CPU _ policy ═ determined, aggregate _ instance _ extra _ tasks, hpgs ═ true, avx512_ vnni, hw, men _ page _ size ═ 1G, and identifies that these target metadata exist simultaneously, determines that the virtual machine type is a vCPU type virtual machine, and sends a request for creating the vCPU type virtual machine at the same time, otherwise determines that the virtual machine type is a vCPU type virtual machine, and sends a request for creating the vCPU type virtual machine at the same time, where hw, CPU _ policy ═ determined is CPU metadata, hw, men _ page _ size ═ 1G, and aggregate _ instance _ extra _ tasks, hpgs ═ avx512 is hard disk metadata.
As an alternative embodiment, after step S103, the method further includes: and checking the acquired creation request and the target metadata, and if the creation request and the target metadata pass the checking, executing a step of selecting target hardware according to the type of the virtual machine.
Specifically, after receiving a creation request for creating a virtual machine, the nova-api service of the cloud computing management platform checks the creation request, target metadata and a virtual machine type to be created, if the creation request and the target metadata both meet a preset check condition, the virtual machine type to be created passes the check, for example, the virtual machine type to be created corresponds to the identification result of the target metadata, the virtual machine type to be created is considered to pass the check, and after the check is passed, the nova-api service transmits a request for creating a vCPU type virtual machine to the nova-vector service; otherwise, the creation process is ended, or a prompt is sent out, so that the probability of wrong selection caused by factors such as BUG (BUG in computer field) and crash of the program is reduced.
Step S104: target hardware is selected for the virtual machine type.
In a specific implementation process, if the type of the virtual machine is a vCPU type virtual machine, selecting hardware corresponding to the vCPU type virtual machine from cloud host resources as candidate hardware, and selecting target hardware from the candidate hardware by using a filtering algorithm; or if the virtual machine type is a vGPU type virtual machine, selecting hardware corresponding to the vGPU type virtual machine from cloud host resources as candidate hardware, and selecting target hardware from the candidate hardware by using a filtering algorithm.
For example, if the nova-conductor service receives a request for creating a vCPU type virtual machine, the nova-conductor service queries a resource management service according to information in a cloud computing management platform, finds candidate hardware suitable for creating the vCPU type virtual machine from a cloud host resource specification, for example, the candidate hardware is a 28-core CPU, a DDR4 memory supporting ECC, a solid state disk, and a large video memory GPU, and then the nova-scheduler service selectively filters the candidate hardware according to filtering algorithms such as a native CPU, a memory, and a large page memory of the cloud computing management platform, so as to obtain target hardware, for example, the target hardware is a 28-core processor, two GPUs each having a 22GB video memory, a 256GB RDIMM type DDR4, and 960GB solid state disks; if the nova-conductor service receives a request for creating a vGPU type virtual machine, the nova-conductor service queries a resource management service according to information in a cloud computing management platform, finds candidate hardware suitable for creating the vGPU type virtual machine from the cloud host resource specification, for example, the found candidate hardware is a 10-core CPU, a DDR4 memory supporting ECC, a solid state disk and a GPU for high floating point operation, and then the nova-scheduler service selectively filters the found candidate hardware according to filtering algorithms of a native CPU, a memory, a large page memory and the like in the cloud computing management platform to obtain target hardware, for example, the target hardware comprises: a 10-core CPU, four GPUs with 22GB video memory, 512GB RDIMM DDR4, 1.2TB solid state disk.
Step S105: and acquiring a configuration file matched with the target hardware, and creating the target virtual machine by using the configuration file and the target hardware.
In the specific implementation process, the CPU of the target virtual machine is bound with the physical CPU by using the configuration file, the hard disk of the target virtual machine is set as a direct hard disk, and the RAM of the target virtual machine is set as a large-page memory.
For example, firstly installing software stacks such as Intel OpenVINO and the like in a VM (Virtual Machine) image, uploading the manufactured VM image to a gloss service in a cloud computing management platform, obtaining a configuration file corresponding to the vCPU Virtual Machine by the nova-computer service after the nova-conductor service in the cloud computing management platform sends a request for creating the vCPU Virtual Machine to the nova-computer service, reading information such as CPU pin, numa, CPU passthrough, target metadata and the like from the configuration file, then calling a bottom layer service of libvirt to generate an xml file about the vCPU Virtual Machine, creating the vCPU Virtual Machine after the VM image is installed by the libvirt, and binding the CPU metadata hw of the CPU Virtual Machine with the CPU metadata hpu after the vCPU Virtual Machine is started by the libvirt, so that the CPU Virtual Machine can be bound with the CPU Virtual Machine, and the CPU can be improved; setting the CPU of the vCPU type virtual machine to be in a host direct-through mode through the CPU metadata avx512_ vnni; the RAM of the vCPU-type virtual machine is set as a large-page memory by RAM metadata hw, men _ page _ size ═ 1G, aggregate _ instance _ extra _ specs:hpgs ═ true.
As an alternative embodiment, after step S105, the method further includes: and starting the target virtual machine and outputting prompt information, wherein the prompt information comprises the creation state of the target virtual machine.
For example, a cloud computing management platform starts a vCPU type virtual machine through libvirt, a nova-computer service in the cloud computing management platform sends information that the vCPU type virtual machine is successfully started to a nova-api service, and the nova-api service sends information that the vCPU type virtual machine is successfully created to a UI.
Furthermore, the full life cycle of the target virtual machine of the inference operation can be managed through the cloud computing management platform, and the management comprises one-key establishment of the inference operation virtual machine, centralized operation and maintenance management of the inference operation virtual machine and the like. The method innovatively realizes the service provision for the reasoning and operation virtual machine by using the mixed resource of the GPU and the CPU. The operation and maintenance efficiency is greatly improved, the cost is saved, the resource utilization rate is improved, and the application scene of the cloud platform is expanded. The virtual machine which only supports the reasoning and operation by the VCPU resources is optimized, the speed of the reasoning and operation model is obviously improved, and the effect that the virtual GPU resources support the reasoning and operation virtual machine is achieved.
The physical resources of the GPU and the CPU are virtualized by means of a virtualization technology, the virtualized GPU and CPU resources are distributed to a plurality of virtual machines, and a user runs reasoning operation service in the virtual machines. The method has the advantages that the one-click establishment of the reasoning operation virtual machine is realized by means of the cloud platform of the OpenStack, and the operation complexity of the construction of the reasoning operation environment is greatly reduced.
The method has the advantages that the mixed resources of the GPU and the CPU are utilized to provide services for the reasoning and operation virtual machines, the performance of the virtual machines is optimized, the reasoning and operation services are operated in the virtual machines, the influence on other virtual machines operated on the same server is avoided, each virtual machine can operate different reasoning and operation models, if the environment of the virtual machine is damaged, the environment of the virtual machine can be established very quickly, more users can use the virtual machine at the same time, and the resource utilization rate of the server is improved.
The technical scheme in the embodiment of the invention at least has the following technical effects or advantages:
