Abstract

The invention discloses a virtual machine migration method relating to the communication technical field. In adoption of the method, the distance restriction of online migration can be effectively relieved. In the method, when a virtual machine needs to carry out long distance online migration between two nodes relatively far apart from each other, firstly, a plurality of relay nodes are selected according to a storage I / O delay restriction; in the migration process, storage data are simultaneously sent to all relay nodes and the target node; when the initial node and the nearest node satisfy a migration condition, a first relay node is triggered to migrate; meanwhile, the network related configuration of the initial node is transferred to the first relay node, thus guiding traffic to the first relay node; after the process is finished, the initial node closes and releases related resources; the initial node is replaced by the first relay node; the first relay node continues to initiate the migration to the next node; the process is repeated until the virtual machine is migrated to the target node. The method and the device of the invention are applicable to a virtual machine migration process.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for migrating a virtual machine. Background technique [0002] With the development of communication technology, especially the popularity of virtualization technology, cloud computing data centers usually use virtual machines to perform tasks. In practical applications, due to the needs of energy saving, disaster recovery, business migration, and nearby services, it is often necessary to change the physical location of service nodes without interrupting business through virtual machine migration. [0003] Virtual machine migration needs to complete two parts of work, one is the migration of the system state. This refers to moving the operating system and applications on the source host to the destination host, and they can run normally on the destination host. The second is the transfer of storage state. If the storage medium is shared b...
