  2. Summary • A year ago, sites were rejecting any possibility of running remotely generated virtual machine images. • Today, we have the skeleton of a scheme that will enable sites to treat trusted VM images exactly as normal worker nodes. • This enables • VOs to be 100% sure of the worker node environment • (potentially) inclusion in the VM image of the pilot job framework enabling “cloud like” submission of work to sites. • Active involvement of VOs is now highly desirable as we move towards delivering a proof-of-concept system. • Nothing in what is being done • prevents sites that wish to do so from implementing Amazon EC2-style instantiation of user generated images, or • precludes use of CernVM. In fact, CernVM-FS looks to be a goodsolution for delivering VO software.

  3. Delivered/Deliverables • Policy for Image Endorsement • Tools for Image Cataloguing & Distribution • Image Contextualisation policy & mechanism • Sites contextualise to • support local policies • Grid policy compliance • NO changes to base image in terms of sw environment • Support for Multiple Hypervisors

  4. Delivered/Deliverables • Policy for Image Endorsement • Seehttps://edms.cern.ch/document/1080777 • Tools for Image Cataloguing & Distribution • Image Contextualisation policy & mechanism • Sites contextualise to • support local policies • Grid policy compliance • NO changes to base image in terms of sw environment • Support for Multiple Hypervisors • Single image format for sites with either Xen or KVM • 90%+ of cases
