If the VM itself is the "physical entity" of the system, the logical
conclusion I come to is that some kind of key should be obtained
through the VM to uniquely give the device a persistent MAC.
You could do things like have the PF controller use the root filesystem
ID label to construct the VF's MAC address, or something like that.
