Abstract

The invention discloses a virtual machine live migration method, a virtual machine migration management apparatus, and a virtual machine live migration system. The method comprises following steps: the virtual machine migration management apparatus maps first mirror image files of a first virtual machine working on a source terminal physical machine to an object terminal physical machine, so that second mirror image files having correspondence relations with the first mirror image files can be generated on the object terminal physical machine; the virtual machine migration management apparatus sends migration commands to the source end physical machine; the virtual machine migration management apparatus controls a second virtual machine to work on the object terminal physical machine through calling memory data of the first virtual machine and the correspondence relations, wherein the memory data of the first virtual machine is stored in the object terminal physical machine, and the second virtual machine is pre-established on the object terminal physical machine and having the same configuration with the first virtual machine; and the virtual machine migration management apparatus synchronizes disk data in the first mirror image files to the second mirror image files when the second virtual machine works on the object terminal physical machine. According to the invention, a technical problem that the live migration time is long due to a pre-copy manner is solved.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a virtual machine hot migration method, a virtual machine migration management device and a system. Background technique [0002] Live migration is an extremely important part of virtualization technology. In a virtualized environment, business loads run on virtual machines, and virtual machines run on physical machines, and each physical machine can run one or more virtual machines; the hot migration function enables virtual machines to Move online from the source physical machine to the destination physical machine. The virtual machine hot migration process mainly includes the migration of disk data and memory data. [0003] Most of the existing hot migration technologies use the pre-copy method to complete the data copy and migration before the end of the virtual machine hot migration (the virtual machine stops running on the source physical machine and starts...
