The ASTRI ("Astrofisica con Specchi a Tecnologia Replicante Italiana") program a collaborative international effort led by the Italian National Institute for Astrophysics (INAF) design and an end-to-end prototype of the same class as the Cherenkov Telescope Array Observatory (CTAO) The prototype, named ASTRI-Horn d'Arturo, is currently in operation at the INAF observing station "G. Fracastoro”, located in Serra La Nave on Mt.Etna (Italy). The ASTRI project is a mini-array of nine ASTRI telescopes to be installed at the Teide Observatory, in the Canary Island.
In order to support the operations of the ASTRI Prototype and Mini-Array, a specific and sophisticated software is necessary. This software be designed and developed following software engineering , i.e. going through the steps of: development, testing, distribution, and version control. . paper we show how the ASTRI Prototype Test Bed has been organized and how the virtual system that hosts it was built. We also present the system hardware architecture and its components and explain how this is used to create a virtualization system, in accordance with the Test Bed requirements. Prototype Test Bed has been exploited to understand and optimize the design of the virtualization system that host the ASTRI Mini-Array Test Bed. For the design of this system we started from the study of a different Open Source virtualization software: ProxMox. This software solves many of the problems we had with the previously adopted software. The decision to use the ProxMox software has a impact on hardware architecture. This kind of architecture can be realized in a very simple and economical wa, performance, redundancy, and reliability requirements.
