Description
On a perfectly working 4.10 node with KVM hypervisor and Ceph RBD primary storage, after upgrading to 4.11, cloudstack agent is unable to connect the BRD pool in libvirt, giving just a generic "operation not supported" error in its logs:

Exactly the same pool was previously working before upgrade:

To workaround the issue I have tried to use the following XML config (dumped from another node where it is correctly running) and define the pool directly in libvirt, and it worked as expected:
<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='be80af6a-7201-3410-8da4-9b3b58c4954f'/>
</auth>
</source>
</pool>
virsh pool-define test.xml
Pool be80af6a-7201-3410-8da4-9b3b58c4954f defined from test.xml

And now the cloudstack agent correctly starts:
