Server consolidation is one of the techniques to reduce the overall energy consumption in the data centers besides various hardware and software features. Virtualization technology (VT) has made this possible with the help of various hypervisors which helps to create the virtual machines (VMs). During consolidation there are various parameters that needs to be thrown light into including performance, SLA (Service Level Agreement), CPU-I/O relation etc. Live migration of VM is the key to consolidating the servers without stopping them thereby with near-zero downtime for the systems. Excessive consolidation causes performance degradation which has severe impact on the QoS (Quality of Service) of the application that are running in that environment. VM allocation and placement are the main issues in consolidation. The performance- energy tradeoffs have been discussed based on Greedy heuristics. Finally the simulation and live demonstration results are plotted.
