             Summary: About Snapshot Operation on KVM with RBD
                 Key: CLOUDSTACK-8302
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8302
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM, Snapshot, Storage Controller
    Affects Versions: 4.4.2, 4.4.1, 4.4.0
         Environment: CloudStack 4.4.2 + KVM on CentOS 6.6 + Ceph/RBD 0.80.8
            Reporter: Star Guo


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 .
