At the moment Quantum enables the user to define a base MAC address.
That is the user can update the configuration file. The user selects
a base MAC and the MAC's are allocated in that range. I think that
this gives us a lot of flexibility. <br>
<br>
Please see below for the configuration options.<br>
<br>
# Base MAC address. The first 3 octets will remain unchanged. If the<br>
# 4h octet is not 00, it will also used. The others will be<br>
# randomly generated.<br>
# 3 octet<br>
# base_mac = fa:16:3e:00:00:00<br>
# 4 octet<br>
# base_mac = fa:16:3e:4f:00:00<br>
<br>
If I recall correctly this is hard coded in nova networking.<br>
<br>
Thanks<br>

we use random MAC OUI, the actual owners can
assert their legal claim on the MAC address in
the event of a conflict now that we have support
for more sophisticated tunnels that allow
