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,
