Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0043] Before explaining the embodiments of the present disclosure in detail, the nouns involved in the embodiments of the present disclosure will be explained first.

[0044] SR-IOV: also known as hard pass-through technology, is a technology that virtualizes a single PCIe device into multiple independent PCIe devices for upper-layer services. The emergence of hard direct technology is mostly to meet the high bandwidth and low latency requirements of applications. For example, with the rapid development of cloud computing technology, more and more applications are deployed on the cloud platform, and some applications have higher requirements for bandwidth and delay, so in order to meet the high bandwidth and low delay requirements...

Abstract

The invention provides a virtual machine creation method and apparatus, and belongs to the technical field of cloud computing. The method is applied to a cloud platform; each computing node of the cloud platform comprises a network card resource pool; and each network card resource pool comprises physical network cards configured in each computing node. The method comprises the steps of receivinga virtual machine creation request, wherein the virtual machine creation request comprises parameter information of a virtual network card occupied by a to-be-created virtual machine; obtaining current resource occupation information of the network card resource pool of each computing node in the cloud platform; according to the parameter information and the current resource occupation informationof each network card resource pool, in at least one computing node of the cloud platform, determining a target computing node used for performing virtual machine creation; and calling the target computing node to create the virtual machine. Network resources of all the physical network cards in each computing node are pooled; performance requirements of different virtual machines can be taken into account during the virtual machine creation; and the resources of the computing nodes are fully and reasonably utilized.

Description

technical field [0001] The present disclosure relates to the technical field of cloud computing, and in particular to a method and device for creating a virtual machine. Background technique [0002] Single-Root I / O Virtualization (SR-IOV, Single-Root I / O Virtualization) technology, also known as hard pass-through technology, is a standard interface (PCIe, Peripheral Component Interconnect express) device pair that interconnects a single peripheral component. In terms of upper-layer services, it is a technology that virtualizes multiple independent PCIe devices. At present, in the field of cloud computing technology, SR-IOV technology has been widely used on the cloud platform. For example, a physical network card supporting SR-IOV technology is configured on the computing node of the cloud platform, so that when the cloud platform creates a virtual machine, it is convenient. A physical network card supporting the SR-IOV technology can be used to generate a virtual function...
