Hi Liu Dong,
Just found a solution for this as following, the method is using fixed ip
as a bridge for MAC and floating ip.
Can you please help check if it is the way that you want me to do? If not,
can you please give some suggestion for your idea?
Thanks,
Jay
==============My steps==============
Suppose I want to bind MAC fa:16:3e:9d:e9:11 to floating ip 9.21.52.22, I
was doing as following:
*1) Create a port for fixed ip with the MAC address fa:16:3e:9d:e9:11*
[root at db01b05 ~(keystone_admin)]# neutron port-create IntAdmin
--mac-address fa:16:3e:9d:e9:11 --fixed-ip ip_address=10.0.1.2
Created a new port:

{"subnet_id": "0fff20f4-142a-4e89-add1-5c5a79c6d54d", "ip_address":
"10.0.1.2"} |
*2) Create a floating ip with the port id created in step 1)*
[root at db01b05 ~(keystone_admin)]# neutron floatingip-create --port-id
b259770d-7f9c-485a-8f84-bf7b1bbc5706 Ex
Created a new floatingip:

*3) Boot the VM with the port id in step 1)*

*4) The VM goes to active with floating ip 9.21.52.22*

+--------------------------------------+--------+--------+------------+-------------+-------------------------------+
*5) Check the VM MAC address, it is FA:16:3E:9D:E9:11 as expected*
[root at db01b05 ~(keystone_admin)]# ssh -i adminkey.priv root at 9.21.52.22
