Managed Block Storage in oVirt
summary
oVirt integrates the Python cinderlib library so storage vendors’ drivers run directly against the array, moving snapshot/clone/provision work into the backend and cutting disk lock time to a few quick API calls. Metadata lives in a new engine schema, connection info (IQN, portals, multipath) is cached, and hosts use os-brick to perform remote attach/detach and present the device via device-mapper. Prototype supports 80+ drivers, shipped as a tech‑preview in 4.3 with several features still missing.
