针对云计算环境下主机资源的负载均衡问题，提出一种分布式的虚拟机迁移方案。首先，该方案建立主机状态域模型，将主机分为不同的负载状态；然后借鉴蚁群算法中信息素的思想进行主机搜索，设计信息素的更新规则，得到待迁移的虚拟机列表和目的主机列表；最后将虚拟机列表和目的主机列表进行匹配，得到虚拟机迁移结果，进行迁移。在Cloudsim环境下进行实验仿真，实验结果证明，使用该方案可获得较好的负载均衡等级。

Aiming at load balancing issue of host resources in cloud computing environment,we propose a migration scheme for distributed virtual machines.Firstly,the scheme establishes a host status domain model,and divides the host into different load statuses.Then it searches the hosts by learning from the pheromone idea of ant colony algorithm and designs pheromone updating rule,thus obtains the list of virtual machines and the list of destination hosts to be migrated.At last it matches the virtual machines list and the destination hosts list to get the virtual machines migration results and makes the migration.Simulation experiment has been carried out in Cloudsim environment, experimental result proves that the proposed scheme can achieve better load balancing rank.
