Hi Jaime, Javier<br>
<br>
Do you think that it would be possible to include these ceph patches
into next 4.8 release? At this moment we are applying theses patches
by hand in our configuration to use different Ceph pools.<br>

Hi Jaime<br>
<br>
Sorry for the late reply, I didn't see your mail before because I
was included in cc. With this patch you don't need to include a
new user into your ceph keyring. If you want to use a ceph
datastore you only need to include the user and pool into the
datastore template that's all. In our case we use livbirt
datastore and we have created two ceph datastore for testing
porposes (each one use a different pool as well):<br>

As you can see we are using different pools in each one (so we
don't need to include the pool name into ceph.conf either, and we
are able to use several ceph clusters) and this change simplifies
the ONE conf and ceph cluster admin as well. <br>
