Example Embodiment

[0039] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0040] Such as figure 1 The dynamic deployment method of a virtual machine shown includes the steps:

[0041] S1 obtains the remaining resources of each dimension on each physical machine and the resource requirements of the corresponding dimension of the virtual machine to be deployed;

[0042] S2 divides the remaining resources of each dimension on each physical machine by the resource demand of the corresponding dimension of the virtual machine to be deployed to obtain a ratio sequence; the smallest ratio in the ratio sequence is used as the maximum capacity of the physical machine;

[0043] S3 selects the physical machine with the largest accommodating number as the target physical machine;

[0044] S4 determines whether the target physical machine has sufficient resources to accommodate the virtual machine to be deployed:

[0045] If the value of the maximum...

Abstract

The invention relates to a dynamic deployment method for virtual machines. The method comprises the following steps: dividing residual resources of each dimension on a physical machine by demanded resource quantity of a corresponding dimension of a to-be-deployed physical machine so as to obtain a ratio sequence, screening out the minimum value of ratios in the sequence and taking the minimum value as the maximum accommodating number of the physical machine to a to-be-deployed virtual machine; selecting a physical machine with the largest maximum accommodating number, and judging whether the physical machine has enough resources to accommodate the to-be-deployed virtual machine; if the value of the maximum accommodating number of the target physical machine is greater than or equal to 1, deploying the virtual machine to the physical machine; and if the maximum accommodating number of the target physical machine is less than 1, outputting that the deployment of the virtual machine fails. By using the method disclosed by the invention, a 'short board' phenomenon, namely, resources of other dimensions are wasted because of the lack of resources of some dimension of a physical machine in a cluster, can be avoided, and the resource utilization ratio of the physical machine can be increased.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a virtual machine deployment method applicable in cluster resource management. Background technique [0002] Virtual machine technology is an important technical means to effectively manage and fully share physical resources. It can introduce an abstraction layer between the software and hardware of a computer system, provide an independent operating environment for upper-layer applications, and shield the dynamics and heterogeneity of lower-layer hardware. To realize the sharing and multiplexing of hardware resources. [0003] The dynamic deployment method of the virtual machine refers to the real-time monitoring and analysis of the resource usage status of the physical machine in the process of physical machine cluster management, and the reasonable adjustment of the CPU, memory, disk bandwidth, network bandwidth and other resources occupied by the virtual machine, and...
