</div>No, you can also use filesystem DS in combination with ssh TM for exemple.<br>

</div>I customized the TM (see <a href="http://blog.opennebula.org/?p=4002" target="_blank">http://blog.opennebula.org/?p=4002</a> ), so that image is<br>
copied from "remote" storage (could be ssh or nfs) to the local LVM. I still<br>
plan to publish these patch, even if they are based on 3.6, so I'll probably<br>
first update them so that they work on 4.x.<br>

</div>If you join OpenNebulaConf in Berlin, I'll give a talk about it Thursday<br>
afternoon (<a href="http://opennebulaconf.com/schedule/" target="_blank">http://opennebulaconf.com/schedule/</a>), I'll be happy to discuss it<br>
with you.<br>
<br>
In a nutshell, you can basically use filesystem DS with a customized version<br>
of ssh TM which creates LV on the flight.<br>
