> On a perfectly working 4.10 node with KVM hypervisor and Ceph RBD primary

> 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:

> <secret uuid='be80af6a-7201-3410-8da4-9b3b58c4954f'/>
