<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
<br>
seems you have already done some reading, <br>
so here is only very brief comments which might <br>
help you understand things for second reading:<br>
<br>
If you don't have an NFS filesystem with (at least)<br>
15*10GB=150GB, you can't do the NFS installation.<br>
<br>
In your case, you want to copy the images to the local disks <br>
of the worker nodes, so you want "<a name="non-shared_-_ssh" id="non-shared_-_ssh">Non-Shared - SSH"</a> described on:<br>
http://opennebula.org/documentation:rel2.2:sm<br>
<br>
Yours,<br>
Steffen<br>
