Abstract
Despite of various benefits such as load balance and energy saving virtual machine (VM) migration promises to provide, its application in realistic data centers is still limited due to the limitation of migration in the LAN environment and the unpredictable performance. Through separation of control plane and data plane, software defined network (SDN) provides the possibility for an alternate solution to overcome these limitations. In this work, we aim at designing and implementing a software defined approach for live VM migration to experiment the possibility. This paper presents the key challenges and our preliminary design result to address these challenges.
