[ovirt-users] Create cinder disk via python sdk

Hi As part of migrating from KVM to Ceph, I'm trying to create a Cinder disk via the python sdk. This is what I have so far and it fails with the message that the cinder type null doesn't exist: disk_attachment = disk_attachments_service.add( types.DiskAttachment( disk=types.Disk( name = 'API_Disk_Cinder_test', format=types.DiskFormat.RAW, provisioned_size=12 * 2**30, storage_domains=[ types.StorageDomain( name='ovirt2-cinder', ), ], openstack_volume_type=types.OpenStackVolumeType( 'ceph', openstack_volume_provider=types.OpenStackVolumeProvider('ovirt2-cinder'), ) ), interface=types.DiskInterface.VIRTIO, bootable=False, active=True, ), ) Doing it similarly with an NFS backend works so I know the connection details are correct, so I didn't bother including them. Regards,
