Virtualization based server consolidation is the fundamental technology in data centers supporting e.g. server cost reduction, cheap HA failover setups or green computing. Virtual machines running on a shared server should be in an idealistic case independent of each other both from the point of view of logical and performability aspects; however, isolation is typically imperfect. The paper proposes a methodology for estimating parasitic interferences between virtual machines running on the same shared host by analyzing the core factors by means of data mining. The consequences to deployment policy are shortly addressed.
