Using Cinder to store VM images (SAN with Fibre Channel)

We are working on a Liberty setup that makes use of an IBM DS6000 that is connected to 2 Brocade Fibre Switches. Each Compute Node has an HBA installed that is connected to each of the Fibre Switches. We want to configure Nova in that way that the VM images are stored in the SAN and not locally on the Compute Nodes' HDDs. The traffic should go entirely through the Fibre Channel network without any ethernet access.

What is the right approach here? Is there any way possible to tell Nova to use Cinder as storage backend for the VM images? Our goal is the accelerate live migration so that the VM's HDDs must not be transfered from one Compute Node to the other.

I have only found this reference here:

I am sure that it is not enough to just install some additional packages. We are planning to use Ubuntu Server 14.04. as OS.
