A method for identifying target server computers for consolidating virtual machines in a virtualized data center includes measuring load constraints for different server computers in a virtualized data center. The method also include rendering in a load graph in a graphical user interface (GUI) for the target identification module different icons, each representative of a corresponding one of the different server computers, each icon in the load graph including a position in the load graph according to measured load constraints for a corresponding one of the different server computers. The method further includes selecting a server computer from amongst the different server computers. Finally, the method includes filtering the load graph in the GUI to exclude icons corresponding to server computers that are over-utilized, so that icons remaining visible in the load graph represent server computers that are suitable as a target server computer for server consolidation of virtual machines executing in the selected server computer.
