<p class="MsoNormal">I've recently upgraded from v4.4 to 4.6. As part of the upgrade, we decided to create a new db using MySQL. The configurations ran smooth, all nodes and datastores are being monitored without issues but when I tried to upload a ttylinux
image for testing, sunstone didn't show the image uploaded on the list. As if it wasn' t even there. I ran the #oneimage list command, and there's no image there either. So I tried uploading again, while I checked the oned.log. I then tried to upload other
images.<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I have OpenNebula front end installed on a host, several other nodes that are speciffic for running the VMs and a NAS with 20TB that holds the datastores. While I was uploading an ubuntu image (20GB), I checked
the transmition rate on the network and I was supprised to see that the traffic between my desktop (where I was uploading from) and the frontend was very heavy, but the datastore was not recieving the image I was uploading.<o:p></o:p></p>
