Openstack++ with two Ethernet Interface

[rim]

Hello,

I have two Ethernet interface eth0 (IP: 192.168.1.4) and eth1 (192.26.4.20). Eth1 is for public internet. I have local subnet so I want to run Horizon, keystone on the host IP: 192.168.1.4 (local subnet) because other network entity are in local subnet and should connect to cloudlet on 192.168.1.4.

Here is my local.conf file:

FLAT_INTERFACE=eth0

PUBLIC_INTERFACE=eth1

But after installing openstack, I see Horizon, keystone and host IP are 192.26.4.20 that is belongs to eth1. How can I change them in eth0. Any idea? Thanks

Hello @rim,

If I understand your wishes correctly, it looks like you simply have to switch the interfaces you have defined fro FLAT and PUBLIC. The PUBLIC_INTERFACE is the one that should be externally accessible and as such, the one you would want to reach Horizon from. The FLAT_INTERFACE is that which is used for communication between the OpenStack controller and compute nodes (though in this case if you used DevStack, the controller and compute are on the same single node).

Another note, if you used DevStack to install OpenStack by executing ./stack.sh, you probably need to start with a fresh install in order to propagate these interface changes to all the necessary files. You should be able to use ./clean.sh to remove everything and then run ./stack.sh again in order to reinstall everything.

Thanks. That's true. I switched the interface. However, in this setting the interface (eth0, IP: 192.168.1.4) does not have access to Internet. Therefore, I can not execute ./stack.sh to reinstall everything. Is there any guideline/way how to manually update the already installed Devstack setting to propagate the interface change?

Finally, the issue is fixed!!

@rim,

Glad you got it fixed! What was the resolution?
