23. Report from the Virtualisation Working Group

Tony Cass (CERN)

11/1/10, 1:30 PM

Virtualization

The presentation will cover the work of the Virtualisation Working Group over the past year.

36. cvmfs - a caching filesystem for software distribution

Mr Ian Peter Collier (STFC-RAL)

11/1/10, 2:00 PM

Virtualization

In common with other sites the RAL Tier 1 experiences performance problems on experiment software servers. CernVM-FS is a caching http based filesystem that may provide an elegant solution. This talk will describe cvmfs and RAL's experience in testing its scalability.

25. A scheme for defining and deploying trusted Virtual Machines to Grid Sites using Configuration Management Systems

Yushu Yao (Lawrence Berkeley National Lab. (LBNL))

11/1/10, 2:30 PM

Sites (service providers) and VOs (service users/functionality providers) are debating how to define trusted VO-provided VM images. We present an alternative scheme that, using a Configuration Management System (CMS), does not require Sites to trust VO-provided images. It gives VO the freedom to design and customize functionalities, while letting Sites retain full control over...

8. Virtualization at CERN: an overview

Helge Meinhard (CERN)

11/1/10, 3:30 PM

Virtualization

This presentation will give an overview over the various virtualization projects going on at CERN. Specifically, consolidation using virtualization has been moved into production mode, and already more than 100 machines are run on this infrastructure, covering a variety of services. The basic concepts of the setup will be presented, and future plans will be described. This presentation will...

32. CERNs image distribution system for the internal cloud

Mr Romain Wartel (CERN)

11/1/10, 4:00 PM

Virtualization

In any large-scale virtualized environment, the image distribution system plays a central role. It is must not only deliver up-to-date images to the hypervisor with appropriate performances, but it should also establish and maintain a sufficient level of trust in the actual images that are being distributed. These issues can be addressed by using a peer-to-peer-based image distribution system,...

51. Status update of the CERN Virtual Infrastructure

Tim Bell (CERN)

11/3/10, 3:50 PM

Virtualization

During 2010, the number of Virtual Machines in the CERN Virtual Infrastructure has doubled to 600. These VMs are owned by a large number of users from very different CERN communities. CVI is based in Microsoft's Hyper-V product, with a web-based self-service and a SOAP interface. We present details of the service architecture, its current implementation and usage, and our plans for...
