Towards self-managed adaptive emulation of grid environments

Distributed systems emulators built with the aid of virtualization tools allow testing of systems in a testbed whose number of real elements are orders of magnitude smaller than the number of virtual elements being tested. However, to allow testers to benefit from these systems, operation of the virtual environment should be hidden from them and performed automatically by the emulator. Moreover, testers may be unsure on the exact needs of their environment, and thus can request an environment that does not fit the experiment. In this paper we present our achievements in providing an emulation framework able to provide environment reconfiguration if the requested one does not comply with experiment´s demands. Also, it supplies services such as execution log, environment monitoring, and automatic management of applications running in the virtual environment.
