   I’m looking at the logic in StorageSystemSnapshotStrategy.java and it 
actually flows like this:
   
   if (volumeInfo.getFormat() == ImageFormat.VHD) {
       HostVO hostVO = getHost(volumeInfo.getId());
   
       computeClusterSupportsVolumeClone = 
clusterDao.getSupportsResigning(hostVO.getClusterId());
   }
   else if (volumeInfo.getFormat() == ImageFormat.OVA || volumeInfo.getFormat() 
== ImageFormat.QCOW2) {
       computeClusterSupportsVolumeClone = true;
   }
   else {
       throw new CloudRuntimeException("Unsupported format");
   }

   @mike-tutkowski<https://github.com/mike-tutkowski> I am now taking into 
consideration if the storage pool is managed or not.
   I first load the storage pool where the volume of the snapshot is storage, 
and then I look for a host that I can use to execute the operation. If the 
storage pool is of managed type, I am going to check the parameter you 
mentioned (‘supportsResign’) in the cluster_details table; I am also expecting 
that property to be set as true if the host supports resign UUIDs.
   
   Thanks for your help here ;)
   
   P.S. As you mentioned, this changes only affect snapshots in XenServer 
environments.

> As default, CloudStack create linked clone snapshot for VM instance . When we

> CloudStack only download incremental VHD as template file, as a result, the 
> VM instance fail to deploy as it is incomplete.
