[one-users] Infiniband, nodes and VMs

[Galimba]

As a first step, I'd like to be able to deploy vms tru IPoIB.
The problem ips that my opennebula frontend does Not have infiniband. Only
the NAS hosting the datastore mover nfs and the nodes running the vms have
IB devices.

Is it possible to get opennebula to deploy using the IB network while using
ethernet as a managing network?
