A Load Balancing Policy for Virtual Desktop Service

In this paper, a virtual machine migration policy for large scale virtual desktop service is proposed. Usually a virtual desktop service is composed of several physical machines, each of which is running several virtual machines. Sometimes virtual machine should be relocated to other physical machine when load balance over the system lost. In this situation, a management server must answer two questions: who should be relocated and where is the destination host The proposed migration policy in this paper is three kinds. We suggest the best policy from the viewpoint of user and system. By experiments, we show that our policy reduce user connect time and increase the number of concurrent virtual machines.
