hi, i want to install openstack for lab purpose in my collage but it contains only network that is private, and some default gateway to connect to external internet ...

10.0.0.0/8 network

i don't have direct connecvity to internet like public ips 179.0.2.0/24 ... that is connected as second eth interface...

so they provided us static ips to our lab systems

10.4.16.0/24

they had one restriction in network like 10.4.15.0/24 is unreachable to 10.4.16.0/24

so i want to deploy openstack in this senario....

i was tried to install each component its fine upto keystone, glance ,.... while coming to nova-network and neutron network i can't find how to configure it ...

what to give in the floating ips... all my systems controller and compute nodes are having only single nics only...

can any one configured with this situation already...

can any one help me.....

You could use 10.4.16.2-100 for your servers, then setup the floating IP address space starting at 10.4.16.101-150. Floating IP addresses are just route-able addresses in your network, they don't have to be public.

Management Network: 10.4.16.0/24 Floating IP Network: 10.4.16.0/24 -- with reservations starting at 10.4.16.101,10.4.16.150.

Assuming this is a lab setup you aren't going to have enough nodes to fill up the 100 IP addresses before you hit the floating addresses.

If you want to follow along with the guides and use more than one Nic then look at using sub interfaces.

The issue is that it expects two different networks for most of the configuration. You could keep it all on the same network for a proof of concept, otherwise you are going to have to talk with the networking guys to get another network added to your ports.
