Hi Ndhuynh<br><br>Ceph storage in OpenNebula is handled as follows:<div><br></div><div>1.- Image Datastores, hold disk images repository as well as images for running VMs in a Ceph volume</div><div>2.- System Datastore holds additional VM files, checkpoints, context disks and the like.</div><div><br></div><div>If you need live-migration the easiest way is to have a shared filesystem for the System Datastore. You don't need to export the whole /var/lib/one, just the datastore directory, though.</div><div><br></div><div>If you do not need to live-migrate VMs you should be ok with a ssh based system datastore....</div><div><br></div><div>Cheers</div><div><br><div><br></div></div><br><div class="gmail_quote">On Wed Nov 05 2014 at 12:09:47 PM Huynh Dac Nguyen <<a href="mailto:ndhuynh@spsvietnam.vn" target="_blank">ndhuynh@spsvietnam.vn</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
