As Ben mentioned, there should be no difference between virtual and physical ports.  Keep in mind that the different QoS modes work on a particular direction of traffic.  Policing works on traffic coming into OVS, and shaping works on traffic going out of OVS.  For example, if you configured policing, it would limit traffic being transmitted from a VM, but it wouldn't affect traffic being transmitted out of the hypervisors itself.
