Method, system and device for creating virtual machine in cloud platform and storage medium

Abstract

The invention discloses a method for creating a virtual machine in a cloud platform. The method comprises the steps of receiving a virtual machine creation request carrying a CPU mode and a CPU instruction model; when the CPU mode is a specified target mode, querying all instruction sets contained in the CPU instruction model; for any node, when any instruction set in all queried instruction sets is not supported by the node, filtering the node; and selecting a target node from the nodes obtained after filtering, and creating the virtual machine based on the target node. By applying the scheme of the invention, the occurrence of an event of failure of creating the virtual machine is effectively avoided, and the reliability of the scheme of the invention is ensured. The invention further provides a system and device for creating the virtual machine in the cloud platform and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, system, device and storage medium for creating a virtual machine in a cloud platform. Background technique [0002] When users use cloud platform products, they often create virtual machines with specific requirements. For example, if they need to support image rendering, audio and video codec operations, deep learning, encryption and decryption operations, etc., the created virtual machine CPUs need to support specific The calculation acceleration of the scene, and the calculation acceleration of these specific scenes often depends on the specific instruction set provided by the CPU, that is, the demand for the calculation acceleration of the special scene is realized by specifying a specific cpu_model. cpu_model, which can be called CPU model or CPU instruction model, is defined as a collection of CPU instruction sets. A cpu_model corresponds to a collection...

Problems solved by technology

[0003] In the cloud platform, for example, the cloud platform based on OpenStack is commonly used, which provides the function of specifying the cpu_model of the virtual machine, but this needs to be realized by modifying the configuration file, that is, first configure the cpu_mode through the configuration file, and then configure the cpu_models configuration item to specify the calculation The cpu_model type supported by the node, which is obviously not flexible enough

After expansion, it is currently possible to specify the cpu_model when creating a virtual machine without relying on the configuration file. However, such a solution can easily cause the virtual machine to be scheduled to a computing node host that does not support the specified cpu_model, that is, to create a specified cpu_model The virtual machine will fail to be created because the CPU architecture of the target computing node does not support it. In order to avoid the failure of creating a virtual machine, the operation and maintenance personnel and users can only be required to be familiar with the CPU architecture of each computing node on the cloud platform, and specify the node that meets the requirements to create Virtual machines, but with the growth of the platform cluster size, this method has higher and higher requirements for operation and maintenance personnel and users, and the failure to create virtual machines occurs more frequently
