Multiple Virtual Machines Live Migration Scheduling Method Study on VMware vMotion

VM vMotion is the key feature of virtualization and it allows a working virtual machine moving to another physical host without disrupting its service. When administrators perform VM vMotion, they need to consider the vMotion sequence, resource allocation problem and then run vMotion one by one by monitoring the whole vMotion process. However, when the data center is larger and needs to be redeployed, it will become highly complicated and manual operation will be very inefficient. Therefore we present the automatically scheduling method of multiple virtual machines migration to reduce operating procedures and minimize the total migration time. Experimental results show that 50% of the total migration time can be reduced.
