OVS could do that, in normal operation. But OVS tries to be as "stateless" as it can be so that it knows what to do if you restart it (perhaps with an rmmod and insmod of the kernel module, as part of an upgrade), or if you reboot. At that point, OVS has to know what MAC address should go there (in some of those cases it even has to actually create the device from scratch). I guess that OVS could record that you changed the MAC address in its database, but it is not what we have done historically. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
