Abstract

The invention discloses a virtual machine hot migration method, a virtual machine migration management device and a system. Wherein, the method includes: the virtual machine migration management device maps the first image file of the first virtual machine running on the source-end physical machine to the destination-end physical machine, so as to generate an image file existing between the destination-end physical machine and the first image file. The second image file of the corresponding relationship; send a migration command to the source physical machine; control the second virtual machine that is pre-established on the destination physical machine with the same configuration as the first virtual machine by calling the first virtual machine stored in the destination physical machine The memory data and corresponding relationship of the virtual machine run on the target physical machine; during the process of the second virtual machine running on the target physical machine, the disk data in the first image file is synchronized to the second image file. The invention solves the technical problem of long thermal migration time due to the adoption of pre-copy.

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...
