Cool.

You can also look in the wiki:
http://www.ovirt.org/develop/release-management/features/storage/cinder-integration/
(Looks dead now, but usually it is up).

Please share your experience with this feature, we live to get feedback.

Cheers,
Nir

Re: [ovirt-users] Using ceph volumes with ovirt

[Alessandro De Salvo]

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 
10:35:29,197::vm::2729::virt.vm::(hotplugDisk) 
vmId=`c189472e-25d2-4df1-b089-590009856dd3`::Hotplug disk xml: address="" device="disk" snapshot="no" type="network">
name="images/volume-9134b639-c23c-4ff1-91ca-0462c80026d2" protocol="rbd">








name="qemu" type="raw"/>



jsonrpc.Executor/5::ERROR::2016-05-30 
10:35:29,198::vm::2737::virt.vm::(hotplugDisk) 
vmId=`c189472e-25d2-4df1-b089-590009856dd3`::Hotplug failed

Traceback (most recent call last):
  File "/usr/share/vdsm/virt/vm.py", line 2735, in hotplugDisk
self._dom.attachDevice(driveXml)
  File "/usr/share/vdsm/virt/virdomain.py", line 68, in f
ret = attr(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", 
line 124, in wrapper

ret = f(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 1313, in 
wrapper

return func(inst, *args, **kwargs)
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 530, in 
attachDevice
if ret == -1: raise libvirtError ('virDomainAttachDevice() 
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 ), 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
