Method, device and system for creating virtual machine

Abstract

The invention discloses a method for creating a virtual machine. The method is applied to a cloud computation system which comprises control equipment and a plurality of host machines. The method comprises the following steps: receiving a virtual machine creating request by the control equipment, wherein the virtual machine creating request comprises first demand information and second demand information of a to-be-created virtual machine, and the first request information is resource demand information; filtering multiple host machines according to the first demand information, the second demand information and attribute information of each host machine, so as to obtain at least one standby host machine; and determining one target host machine from at least one standby host machine, and creating the virtual machine on the target host machine. According to the method provided by the embodiment of the invention, the host machine is selected for the to-be-created virtual machine in multiple aspects, so that the success rate of creating of the virtual machine is increased.

Description

technical field [0001] The present invention relates to the field of cloud technology, in particular to a method, device and system for creating a virtual machine. Background technique [0002] A cloud computing system usually includes a control device and a large number of host machines. The control device can simulate and create one or more virtual machines on a host machine through virtual machine software, and these virtual machines work like real computers. [0003] Because there are a large number of host machines in the cloud computing system, when creating a virtual machine, it is necessary to choose which host machine to create the virtual machine on. In the prior art, it is usually based on the hardware resource requirements of the virtual machine to be created, for example: several central The processor (Central Processing Unit, CPU), how much memory is required, and the demand for resources that the host can provide. [0004] In the prior art, the host machine s...
