As of essex libvirt has an image cache to speed startup of new instances. This cache stores images direct from glance, as well as resized images. There is a periodic task which cleans up images in the cache which are no longer needed. Do we want to implement this for other hypervisors as well? Additionally, the blueprint (https://blueprints.launchpad.net/nova/+spec/nova-image-cache-management) proposed that popular / strategic images could be pre-cached on compute nodes. Is this something we still want to do? What factors do we want to use for the reference implementation? (Session lead is Michael Still)
