Hi Logen, 

I'll refer only to using authentication , because I had configured it previously. 
This means: /etc/cinder/cinder.conf should have: auth_strategy = keystone 
I'm using keystonerc file, example keystonerc_admin: 
---------------------------------------------------------------------------- 
unset OS_SERVICE_TOKEN 
export OS_USERNAME=admin 
export OS_PASSWORD=password 
export OS_AUTH_URL=http://CINDER-HOST:5000/v2.0 
export PS1='[\u@\h \W(keystone_admin)]\$ ' 

export OS_TENANT_NAME=admin 
export OS_REGION_NAME=RegionOne 
---------------------------------------------------------------------------- 

This will be step by step as much as possible just to make sure nothing is missed (assuming Cinder and Ceph are configured correctly). 

Go to: 
External providers -> Add 
Fill in the fields: 
Name: 
Type: OpenStack Volume 
Provider url: http://CINDER_HOST:8776 
Check "Requires Authentication" 

Fill in the information, this is an example: 
Username: admin 
Password: password 
Tenant name: admin 
Authentication URL: http://CINDER-HOST:5000/v2.0 

Test should return "Test succeeded, managed to access provider." 
Now click Ok. 

Now lets configure additional information: 

Lower pane: Authentication Keys 
Click on: New 
Fill in UUID field with rbd_secret_uuid 
and value :which is the key (it's in /etc/ceph/ceph.client.USERNAME.keyring) 

Hope this helps.. 

Regards, 
Natalie

I've got Cinder configured and pointed at Ceph for it's back end storage. 
I can run ceph commands on the cinder machine and cinder is configured for 
noauth and I've also tried it with Keystone for auth. I can run various 
cinder commands and it'll return as expected. 

When I configure it in oVirt it'll add the external provider fine, but when 
I go to create a disk it doesn't populate the volume type field, it's just 
empty. The corresponding command for cinder: cinder type-list and cinder 
type-show <name> returns fine and it is public. 

Ovirt and Cinder are on the same host so it isn't a firewall issue. 

Cinder config: 
[DEFAULT] 
rpc_backend = rabbit 
#auth_strategy = keystone 
auth_strategy = noauth 
enabled_backends = ceph 
#glance_api_servers = http://10.128.7.252:9292 
#glance_api_version = 2 

#[keystone_authtoken] 
#auth_uri = http://10.128.7.252:5000/v3 
#auth_url = http://10.128.7.252:35357/v3 
#auth_type = password 
#memcached_servers = localhost:11211 
#project_domain_name = default 
#user_domain_name = default 
#project_name = services 
#username = user 
#password = pass 

[ceph] 
volume_driver = cinder.volume.drivers.rbd.RBDDriver 
volume_backend_name = ceph 
rbd_pool = ovirt-images 
rbd_user = cinder 
rbd_secret_uuid = <secret> 
rbd_ceph_conf = /etc/ceph/ceph.conf 
rbd_flatten_volume_from_snapshot = true 
rbd_max_clone_depth = 5 
rbd_store_chunk_size = 4 
rados_connect_timeout = -1 
#glance_api_version = 2 

[database] 
connection = postgresql:// user:pass@10.128.2.33/cinder 

[oslo_concurrency] 
lock_path = /var/lib/cinder/tmp 

[oslo_messaging_rabbit] 
rabbit_host = localhost 
rabbit_port = 5672 
rabbit_userid = user 
rabbit_password = pass 

Regards, 
Logan
