Problems solved by technology

Second, the Raid card is faulty
Third, the physical machine is overloaded
However, with the continuous expansion of cloud service providers, the load changes of virtual machines show the characteristics of random load fluctuations, and then frequent migration of virtual machines, frequent migration congestion of virtual machines, and the decline in cloud service quality

Embodiment Construction

[0032] In order to make the technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] figure 1 It is a specific implementation manner of the virtual machine migration method under random load according to the present invention. In this embodiment, the virtual machine migration method under random load is used for virtual machine migration between host clusters, including steps s1-s6 and q1-q3.

[0034] Step s1, traversing each of the hosts, and correspondingly obtaining the resource utilization rate of each host.

[0035] Wherein, the resource utilization is CPU usage.

[0036] Step s2 , comparing the resource utilization rate of the host currently traversed and obtained in step s1 with the preset lower threshold of resource utilization rate and upper threshold value of resource utilization rate.

[0037] Wherein, t...

Abstract

The invention provides a virtual machine migration method and system under random load, Used for virtual machine migration between host clusters, when the resource utilization ratio of the traversingacquired host is higher than the preset resource utilization ratio upper threshold value, both of the traversing acquired host and the traversing acquired host determine the virtual machine to be moved out of the host, and determining a destination host of a virtual machine to be moved out of the determined host, optimizing a network and a disk IO of the determined destination host for moving in the virtual machine to be moved out of the determined host, and starting migration; Determining a destination host for all virtual machines in the host when the resource utilization ratio of the acquired host is lower than a preset resource utilization lower threshold value, optimizing the network data processing capability of the destination host for all virtual machines in the host, and then starting migration. The invention improves the cloud service quality by improving the migration rate of the virtual machine in the cluster.

Description

technical field [0001] The invention relates to the field of virtual machines, in particular to a virtual machine migration method and system under random loads, which are used for virtual machine migration under random loads. Background technique [0002] With the gradual expansion of the scale of cloud service providers in recent years and the gradual enrichment of cloud computing product lines, the applications running in virtual machines in data centers show diversity and heterogeneity. The increasing performance of computers allows more virtual machines to run simultaneously in one host. A large number of virtual machines in the data center have different types and quantities of resource requirements at a certain moment, and when multiple virtual machines with different resource requirements are mapped to the same host, the load fluctuation of the host will become severe And unpredictable. [0003] Virtual machine migration plays a significant role in the data center ...
