Picture of my network topology. Is it right?

Hey guys, I'm trying to set up openstack in a test environment at home. I'm using this guide as all my nodes are running ubuntu 12.04:

I've reached the networking part of the tutorial and this is where I'm confused. Can you please have a look at my network topology and tell me if I set it up wrong? Just note the two servers labeled Controller and compute1, the rest of the network is simply to show you what kid of network I have at home:

One of the specific questions I have is which machine do I run these commands on Controller or Compute1?

Thanks for the response.

I do have another question. The guide says eth0 on compute1 should not be configured with an IP address at all. But the /etc/hosts file on controller has compute1 mapped to How will controller communicate with compute1 if I drop the IP on compute1? Also what should the /etc/network/interfaces on compute1 look like (the eth0 part specifically)

The network topology is fine for the test setup. Let eth0 be your management network and eth1 will be your data network, If you want to go with nova-network , then you should install nova-network on compute node i.e compute1.

or else we can go with neutron which is the separate networking component in Openstack. For that we need to install neutron-server,dhcp-agent,l2-plugin,l3-agent on controller and l2-agent on compute node.
