Hello Slawek and all,

You are right, I forgot to mention that I want to set a specific IP, so
yes I am using the parameters you describe (v4-fixed-ip).

However when trying to use both the v4-fixed-ip and v6-fixed-ip, it does
not work. It seems that those params are mutually exclusives [1] on
client side.

Does anyone know if the server would accept more than one fixed-ips?
My attemps were not sucessful regarding this matter.

Another question is the accessIPv4 (and v6) params, does anyone know
what they are used for? Because they seems completely ignored by neutron
when used on nova client side [2].
