Virtualization of OS is the technology driving all modern data centers. Along with benefits such as reduced costs and easy implementation, virtualization provides the capability to migrate live Virtual Machines (VM) across nodes of a cluster. The existing technology requires manual selection of VMs for live migration which involves redundant migration and hence, not a feasible and efficient solution for large data centers. In this paper, we introduce an automated consolidation technique to reduce the number of active nodes in a cluster. This proposed technique consists of two modules namely consolidation and load balancing which help in achieving the least number of active nodes on the cluster where each VM satisfies Software Licensing Agreement (SLA). This facilitates in achieving quick live migration and node setup while reducing useless migrations which adversely impacts cluster performance. The implementation of the proposed technique has resulted in successful live migration on cluster and consolidation of VMs to minimum number of nodes in the cluster at any given time.
