Hi Antanas, Using ssh drivers and persistent images does not mean that the copy is not necessary, since the image DS doesn't have to be accesible as a local filesystem in the virtualization node. On VM shutdown, if the image is persistent it will be copied back to the datastore to avoid losing changes.
