Hi , I am trying to integrate openstack cinder-volume with vmware datastore. I have already integrated Vcenter with nova. With the same setup now I am working on this cinder integration. I have setup architecture as follows..

I installed nova-compute service in controller for vcenter integration which has nova-network for networking. I have 1 ESXI server added as a compute code. I have launched 3 virtual machine in ESXI host using openstack horizon which occupied half of the Datastore space. I am trying to use the remaining datastore space of ESXI host for Vmware-cinder integration.

Before trying vmware-cinder integration I have installed default cinder service in my icehouse openstack setup. In that I was successfully able to create Volumes.

Then, I followed this reference link for cinder-vmware integration.

I have added the following line in cinder.conf file:

volume_driver = cinder.volume.drivers.vmware.vmdk.VMwareVcVmdkDriver

vmware_host_ip=192.168.1.15

vmware_host_password=**

vmware_host_username=Administrator

vmware_wsdl_location=http://opt/stack/vmware/SDK/vsphere-ws/wsdl/vim25/vimService.wsdl

Then I created storage policy (name=thin) with tag (name=sample) in vcenter. Then I mapped the existing datastore with the created storage policy.

Now, when I am try creating the cinder volume I recevied the following error message in cinder-scheduler.log

No backend provided, not calling functor 'taskflow.storage.SingleThreadedStorage._save_task_detail' _with_connection /usr/lib/python2.7/dist-packages/taskflow/storage.py:88

Could anyone help me with solution ?
