Hi Andrew,
thanks for the prompt reply.
I'm using fixed ip addresses, not floating IPs. In terms of Heat it
looks like there:
n1-wan:
type: OS::Neutron::Port
properties:
name: n1-wan
network: e-net
fixed_ips: [ { subnet: e-subnet, ip_address: X.X.X.X } ]
n1:
type: OS::Nova::Server
properties:
name: n1
networks:
- port: { get_resource: n1-wan }
and there are some constraints in my installation:
1. I can't move ports between VMs (in order to support predictable
naming according to port roles, their MAC addresses are stored in
udev rules inside VM and if I will change port, rules/roles will fail)
2. I don't want to use floating ip due to possible performance
degradation when using massive NAT
Another idea I have is to move ports between VMs, changing their MACs
accordingly and will try it if no other ways will be found :)
Thanks again.

Hi
You can use fixed ip port for this.
create neutron port and attach it to the one vm.
or
you can use floating ip for this purpose as well

Hi colleagues,
imagine, somebody (e.g. me :-) ) needs to transfer IP address between
two ports. The straight way is: release IP address and then assign it
to another port.
The possible problem with this way is time between release and
assignment - during this time, this IP address is in DHCP pool and
can be automatically assigned to some another port upon request.
Any ideas how to prevent leasing this IP address during this time?
Thank you.
