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...

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,...

Inventory and monitoring are two areas that have become more important at LEPP over the last few years in the IT area. We've had increased requirements to track what computers we buy, who gets them "out of stock" and various status changes, from location changes through to disposal.
Knowing where a computer is located is only part of the battle. Important servers and systems must be tracked...
