IIUC originally this collection was suppose to keep all disks that can be shared between different vms and/or available to be attached to certain vm. At the moment this collection contains all disks in system while engine does not provide any search capabilities for it, in my view it not really useful, till we add search capabilities for being able: 1. locate <shareable>true</shareable> disks 2. distinguish between <shareable>true|false</shareable> and <active>true|false</active> disks 3. maybe even worth taking <active>false</active>&&<shareable>false</shareable> out of this collection and place them under api/clusters/xxx/disks (or under DC). this way /api/disks will only have disks that can be shared. your thoughts? -- Michael Pasternak RedHat, ENG-Virtualization R&D
