After many years of operation the client/server architecture of the EPICS-based control system at the synchrotron light source DELTA has been modernized. Due to successive augmentation with additional computers for dedicated tasks, the previous topology grew in the course of time. As a result the maintenance effort increased while the efficiency of the processor load decreased. The introduction of virtualization methods helped to tackle this issue. After evaluation and testing, different implementations were put into action. Pros and cons of the various virtualization solutions are discussed and the experiences with the introduction into an already running EPICS based control system are summarized in this article as well.

The 1.5 GeV electron storage ring at the university light source DELTA suffers from fast orbit movement. Its frequency spectrum points to girder movement, line frequency and its harmonics and the influence of the booster ramp as the sources of beam position noise. Fast orbit feedback systems developed at the DIAMOND light source and the Syncrotron SOLEIL ready to cope with this kind of beam noise are based on I-Tech Libera BPM electronics. Based on the XUPV2P FPGA development board we have developed a digital frontend for the Bergoz MX-BPMs employed at DELTA that integrates seamlessly into the feedback loops based on I-Tech Liberas. A fast local orbit feedback has been set up so far. It will be extended to a global orbit feedback in the near future.
