Abstract

The invention provides a dynamic migration method for a virtual machine, which is applied to a cloud platform and comprises the following steps: acquiring a resource utilization rate parameter of each host in a cluster at present; preprocessing according to the resource utilization rate parameter of each host; determining an idle degree corresponding to the current host according to the preprocessed resource utilization rate parameter and a DS evidence theory; the to-be-migrated virtual machine in the source host is migrated to the target host, the source host is the host with the resource utilization rate exceeding the preset threshold value, the target host is the host with the maximum idle degree at present, the invention further provides a virtual machine dynamic migration device and equipment and a medium, cluster efficiency is improved, and full utilization of cloud platform resources is achieved.

Description

technical field [0001] The present invention relates to the field of virtual machine migration, in particular to a virtual machine dynamic migration method, device, equipment and medium. Background technique [0002] In the cloud platform, the hardware resources are gathered together through the network, and then the hardware resources are virtualized through the virtualization technology, so that the hardware allocation can be realized by creating a virtual machine on the physical host. Compared with the actual cluster, the hardware cost is greatly reduced, and the performance requirements for the server are also reduced. [0003] However, when too many virtual machines are distributed on a single host, it is easy to cause the physical resources to reach the limit alarm value, thereby causing the system to crash; the solution in the prior art is mainly to randomly migrate the virtual machines on the host that has reached the limit alarm value to However, although this meth...
