Attempting to set up Legacy Networking on Icehouse on Ubuntu 14.04

I have a compute node with a single physical connection on eth1 to our shared lab network switch.

The default configuration uses the following in the nova.conf file

network_manager = nova.network.manager.FlatDHCPManager

this indicates to me that an instance will use DHCP to get an IP address from our external subnet. Is there a way to configure legacy networking to not use DHCP and allow us to hard-code IP addresses on the instances from a pool of IP's on our lab subnet without using DHCP?

Just a clarification. Next to your eth1 I assume you are having a connection on eth0 (that is for the management network) ... The thing is that the legacy "nova-network" will manage the ips to give to your vm instances and i thinik for that purpose it uses DHCP. you can use floating ip to assign specific ips to your instances.

Ok thanks. Yes, eth0 is for mgmt. I will take a look at the floating IP assignment. I was hoping to not have to mess with it and just use hard-coded IP's since this is just for lab testing.
