Hi,
just to answer myself, I found these instructions that solved my problem:
http://7xqb88.com1.z0.glb.clouddn.com/Features_Cinder%20Integration.pdf
Basically, I was missing the step to add the ceph key to the
Authentication Keys tab of the cinder External Provider.
It's all working now.
Cheers,
Alessandro

Hi,
I'm happily using our research cluster in Italy via gluster, and now
I'm trying to hotplug a ceph disk on a VM of my cluster, without success.
The ceph cluster is managed via openstack cinder and I can create
correctly the disk via ovirt (3.6.6.2-1 on CentOS 7.2).
The problem comes when trying to hotplug, or start a machine with the
given disk attached.
In the vdsm log of the host where the VM is running or starting I see
the following error:
jsonrpc.Executor/5::INFO::2016-05-30

failed', dom=self)
libvirtError: XML error: invalid auth secret uuid
In fact the uuid of the secret used by ovirt to hotplug seems to be
the ceph secret (masked here as <base 64 ceph secret>), while libvirt
expects the uuid of the libvirt secret, by looking at the instructions
http://docs.ceph.com/docs/jewel/rbd/libvirt/.
Anyone got it working?
Thanks,
Alessandro
