Open Stack

Hi All,

I'm deploying OpenStack Havana for provisioning VMs using ESXi as a 
hypervisor.
I want to use ESX datastore as a cinder backend storage. However, when I 
try to create a volume,
it gives me the following error.

Failed to schedule_create_volume: No valid host was found.

Provided is the driver configuration file which I am using.

volume_driver=cinder.volume.drivers.vmware.vmdk.VMwareEsxVmdkDriver
vmware_host_ip=<vmware_host_ip>
vmware_host_username=<vmware_host_username>
vmware_host_password=<vmware_host_password>

Does anyone have any idea? Pointers in the right direction are always 
welcome.

Thanks in advance.

Regards,
