Abstract:	In this paper we consider how energy efficiency aspects can be added to Openstack. With the objective of devising an energy efficient resource manager for Openstack, we first analyze resource and energy utilization on our cloud resources. We observe that there is a large fixed cost associated with server usage patterns and powering down servers is necessary to achieve energy savings. Following this we consider migration mechanisms which are necessary to perform load consolidation: we find that hybrid live migration has the necessary robustness to be part of a sophisticated load management solution. Finally we discuss ongoing work on realizing a load manager for Openstack based on these observations.
