A QoS Based Migration Scheme for Virtual Machines in Data Center Environments

초록

We propose a QoS based migration system for virtual machines in data center environments. In order for our QoS based migration scheme to ensure QoS requirements for virtual machines, it estimates the QoS during migrations for each virtual machine, and selects the virtual machine that is most likely not to violate its QoS requirement. Moreover, it improves the overall system utilization by choosing the destination server for migration to balance resource usages.
