Different virtualization techniques are in use at the DESY data centers, with Xen servers being the dominant hypervisor. Besides its open source implementations, DESY, location Hamburg, has set up a pool of DELL servers with NetApp storage and Xen Enterprise software to provide a highly available, scalable, and versatile environment for manging data center services on various Windows...

A high availability service is one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new...

Virtualization allow multiple virtual machines to run on a bare bone single hardware. There are many benefits in using Virtualization, fast disaster recovery, OS and software testing, maximization of hardware resources, server consolidation. INFN is using open source virtualization in different contexts mainly with Xen, but KVM is an interesting emerging technology ready for production...

Virtual machines can have many different deployment scenarios and therefore may require generation of multiple VM images. We report on work that has been done in a collaboration between CERN's Grid Deployment group and openlab to address several issues with image generation. Libsfimage is a standalone application which generates VM images with a rich selection of Linux distribution. OSFarm...
