I have set debugging on one of the agents and this is what I get:
```

```
In the generated XML there isn't the secret part, perhaps the agent is trying to use another authentication mechanism which this version of libvirt does not support?
This is what I have been using as a workaround, and it works:
```
<pool type="rbd">
<name>be80af6a-7201-3410-8da4-9b3b58c4954f</name>
<uuid>be80af6a-7201-3410-8da4-9b3b58c4954f</uuid>
<source>
<name>cephstor1</name>
<host name='storagepool1' port='6789'/>
<auth username='admin' type='ceph'>
<secret uuid='OMITTED'/>
</auth>
</source>
</pool>
```
