Virtualization over a Cluster Tiberiu Socaciu, Bogdan Patrut Department of Business Information Systems, ”Stefan cel Mare” University, Suceava, Romania Department of Mathematics and Informatics, University of Bacau, Romania [email protected], [email protected]

At this moment, the LINUX kernel is used as virtual device at different levels for various virtualized environments like Xen [4], VMware [5], IBM Hypervisors [6], User Moder Linux(UML) [2], and others. In this paper we will present our project that consist in virtual machines over a computer cluster. We choose UML for a virtualization schema and a MPI [1] based computer cluster. The advantage of this architecture is the posibility of running ordinary (concurrent) Linux programs in real parallel mode without any modification or adaptation like running on a single interface system (Mosix [7] or OpenMosix [8] architecture. The inverse schema (MPI over UMLs) was presented in [2] Our ideea can be considered (after implementation) as a ”Green IT Technology” (like all virtualization projects).
