Cloud virtual machine migration method, apparatus and system for

The present invention discloses a method for migrating virtual machines cloud, cloud computing belongs, the present invention is designed to run dynamic tracking each host cloud computing system reliability and performance of load variation, the decision timing and adaptive control, and in the migration of virtual machines between hosts process, make a timely response to changes in system load and reliability, which improves load Ping Heng of the system and improve mission reliability. The invention fully considers the dynamic cloud system load fluctuations, changes in the system by tracking the trend forecasting future trends, and VM migration in advance in order to improve load balancing, the present invention will lapse into account the possibility of PM load balancing, the VM migration task strategy can both performance and reliability, while the present invention is variable according to the state of the dynamic system the calculation control interval, to avoid the two extreme "control too close" and "control depopulated."
