Virtual Machine Live Migration Method, Virtual Machine Deployment Method, Server, and Cluster System

摘要

A virtual machine live migration method includes: acquiring load information of physical machines in a first physical machine group, where the physical machines share a same access switch; determining a source physical machine and a destination physical machine according to a first dynamic resource scheduling policy and the load information of the physical machines; and delivering a migration instruction to the source physical machine according to a second dynamic resource scheduling policy. In the foregoing method, virtual machine live migration is performed preferentially within a physical machine group so that network traffic of the migration passes through only one access switch. This shortens a length of a data transmission link, increases a migration rate, and relieves impact of migration traffic on network load in a cluster.

1. A virtual machine live migration method, comprising:
acquiring load information of physical machines in a first physical machine group, wherein the physical machines in the first physical machine group share the same access switch; determining a source physical machine and a destination physical machine in the first physical machine group according to a first dynamic resource scheduling policy and load information of the physical machines in the first physical machine group, wherein the source physical machine is a physical machine whose load information exceeds a first threshold, and the destination physical machine is a physical machine whose load information is lower than a second threshold, wherein the first threshold is higher than the second threshold; and delivering a migration instruction to the source physical machine according to a second dynamic resource scheduling policy, wherein the migration instruction comprises an identifier of a virtual machine to be migrated and an identifier of the destination physical machine, so that the source physical machine migrates, according to the migration instruction, a virtual machine on the source physical machine and corresponding to the identifier of the virtual machine to be migrated to the destination physical machine corresponding to the identifier of the destination physical machine, so as to make load information of the destination physical machine and the source physical machine lower than the first threshold.
