Here are some screenshots of this behavior in 4.3. In 4.4 it is the same.

> Volumes are incorrectly identified as OVM volumes when RBD is used (due to RBD and KVM using RAW format in the backend & OVM being assigned sole responsibility of all RAW volumes on line 1451 of server/src/com/cloud/storage/StorageManagerImpl.java) and this prevents snapshotting. The current (VERY BAD) fix is to change the return "HypervisorType.OVM" under the RAW case to "HypervisorType.KVM". Of course, this has ramifications for OVM users. I will be looking at developing an actual proper fix for this.
