Anytime you change the MAC address of a physical or virtual device away from the (hopefully) globally unique address in the factory settings it is a good idea to set the locally administrated bit as well. It makes it easier when analyzing network traces to see what are from physical and what are from virtual devices. So I say yes, set that bit. regards ronnie sahlberg -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
