Problems solved by technology

[0005] The computing node where the created processing module is located may be different from the computing node where the created volume is located. In this way, the processing module can only read and write volumes remotely through the network, which cannot meet the performance requirements of high-speed read and write volumes.

Embodiment Construction

[0110] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0111] This embodiment is applied to the Openstack platform, which is an open source cloud platform for creating virtual machines. Users can submit a virtual machine creation request to the Openstack platform, and request the Openstack platform to create a virtual machine for them. The virtual machine includes a processing module and a volume. The processing module is an operation logic part of the virtual machine. The volume is a storage module for the processing module to read and write.

[0112] see figure 1 , the Openstack platform includes a processing module creation entity, a volume creation entity, and a computing node. The computing node includes hardware resources such as CPU (Central Processing Unit, processor), memory, and h...

Abstract

The invention discloses a method and a device for creating a virtual machine, belonging to the communication field. The method includes: negotiating with the volume creation entity on the computing node where the processing module included in the virtual machine to be created and the volume are located; creating the processing module on the computing node; receiving the volume of the volume sent by the volume creation entity Identification information, the volume is created by the volume creation entity on the computing node; according to the volume identification information, the volume is mounted on the processing module to form the virtual machine to be created. The device includes: a processing unit and a receiving unit. The invention can meet the performance requirements of high-speed reading and writing volumes.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for creating a virtual machine. Background technique [0002] Openstack (an open source cloud computing management platform) is an open source cloud platform for creating virtual machines. Virtual machines include processing modules and volumes for processing modules to read and write access. Openstack provides Nova (computing resource management) components and The Cinder (block storage resource management) component is used to create processing modules and volumes respectively. [0003] Currently, when creating a virtual machine, the Nova component obtains the virtual machine specification information of the virtual machine to be created, selects a computing node, and creates a processing module of the virtual machine on the computing node according to the virtual machine specification information; the Cinder component obtains the virtual machine to be created Acc...
