Configuring /etc/network/interfaces in a 2 nodes scenario
Hi guys, I'm trying to set up a testing environment with just 2 nodes (based on Ubuntu 12.04.4 and Havana as version of OpenStack).
Controller / Networking node: keystone, glance, neutron...
eth0 local network
eth1 public internet
Compute node: nova-compute
eth0 local network
I'm trying to config Neutron: specifically at step 5 of Install the Open vSwitch (OVS) plug-in, in Install and configure the Networking plug-ins, Chapter 9 section about Install Networking services on a dedicated network node, of the installation guide, I have these instructions:
"Configure the EXTERNAL_INTERFACE without an IP address and in promiscuous mode. Additionally, you must set the newly created br-exinterface to have the IP address that formerly belonged to EXTERNAL_INTERFACE."
In my scenario, I would have:
MGMT_INTERFACE: eth0, br-int
DATA_INTERFACE: eth0, br-data,
EXTERNAL_INTERFACE: eth1, br-ex.
I'm looking for a working configuration of the /etc/network/interfaces file both for the controller and compute nodes, but I still have some doubts...
- Is it possible to have MGMT_INTERFACE and DATA_INTERFACE in the same physical interface?
- In my case, for which interfaces I have to set promiscuous mode?
- ...
(Sorry but due to my low karma level on the website, I can't upload images or post links.)
