<p>Ceph won't be the default image datastore, but you can always choose it whenever you create an image.</p>
<p>You said you don't have an NFS disk and your just use plain disk on your system datastore so you <strong>should</strong> use ssh in order to have live migrations. </p>
<p>Mine uses shared as datastore since I mounted a shared folder on each nebula node. </p>

<p>You don't need to replace existing datastores, the important is you edit the system datastore as "ssh" because you still need to transfer files in each node when you deploy a VM.</p>

<div>So I lose live migration, right?</div>
<div>If I understand correctly ceph cannot be default datastore also. </div>

<p>Next, you should make sure that all your node are able to communicate with the ceph cluster. Issue the command "ceph -s" on all nodes including the front end to be sure that they are connected to ceph.</p>

<div>I see in your configuration that system datastore is shared!<br /><br /></div>
