• Libvirt packages with RDB support have to be installed on host
• Enable ceph repo to install rbd dependencies

[ceph-noarch]

name=Ceph noarch packages

baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/noarch 

• When RBD storage pool is added as primary storage following xml is sent for pool creation on host

<pool type='rbd'>
<name>ae84381b-c273-3c8e-925f-8e384d3216b4</name>
<uuid>ae84381b-c273-3c8e-925f-8e384d3216b4</uuid>
<source>
<host name='10.147.59.89' port='6789'/> - Monitor host
<name>rbd</name> - Pool name
<auth username='admin' type='ceph'>
<secret uuid='ae84381b-c273-3c8e-925f-8e384d3216b4'/> - secret containing auth key
</auth>
</source>
</pool>

• Secret contains authentication details. Secret is created when RBD pool is created

<secret ephemeral='no' private='no'>
<uuid>ae84381b-c273-3c8e-925f-8e384d3216b4</uuid>
<usage type='ceph'>
<name>admin@10.147.59.89:6789/rbd</name>
</usage>
</secret>
