    @dmytro-shevchenko you are changing XenserverSnapshotStrategy from the storage engine
and KVMStorageProcessor from the kvm hypervisor plugin. It seems that you are solving this
for two hypervisors half. Can you explain what you encountered in the code to come up with
this solution?

> I just build a lab with CloudStack 4.4.2 + CentOS 6.6 KVM + Ceph/RBD 0.80.8.
> I deploy an instance on RBD and I create the ROOT volume snapshots. When delete a snapshot
the UI show OK, but the snapshot of the volume in the RBD pool is still exist.
> And I find the code in com/cloud/hypervisor/kvm/storage/KVMStorageProcessor.java: 
> …
>     @Override
>     public Answer deleteSnapshot(DeleteCommand cmd) {
>         return new Answer(cmd);
>     }
> …
> deleteSnapshot() does not be implememented. And I also find the code:
> ...
>     @Override
>     public Answer createTemplateFromSnapshot(CopyCommand cmd) {
>         return null;  //To change body of implemented methods use File | Settings | File
Templates.
>     }
> ...
> So does createTenokateFromSnapshot(). I just look for it in MASTER branch but not do
that yet. Will CloudStack Dev Team plan to do that ? Thanks .
