How many NIC do I need for installing Essex

Hi all,

I'm following;
Expreimenting with OpenStack Essex on Ubuntu 12.04 LTS under
http://www.tikalk.com/alm/blog/expreimenting-openstack-essex-ubuntu-1204-lts-under-virtualbox

building OpenStack, Essex.

But I can't resolve how many NICs I need to install Essex? To my understanding on the diagram - Quick Overview of The Installation

eth0 = NIC-0
eth1 = NIC-1
eth2 = NIC-2

then it needs 3 NICs.

On the other hand;
vboxnet0 and vboxnet1 are virtual NIC

then it needs 2 NICs, one for NAT.

But I have only ONE NIC on the box. Is there any solution? Please help. TIA

B.R.

Hi Stephen,

That installation requires only one physical NIC. All the NICs shown in the
diagram are virtual - created by virtualbox.

Re: How many NIC do I need for installing Essex [In reply to]

Hi Paul,

Thanks for your advice.

Can I replace;
172.16.0.254 with 192.168.0.100

and

11.0.0.1 with 192.168.0.101
?

Because 172.16.0.254 and 11.0.0.1 are not in the range of IP address of the router

B.R.
Stephen L

Re: How many NIC do I need for installing Essex [In reply to]

Those are loopback interfaces created on your host machine, not real
routing interfaces. They should *not* be part of an existing routed network
that you are using. So if 192.168.0.0/24 is a network that you are already
using this environment, then do *not* use those for the vboxnet addresses.
It should work with the IP addresses in the blog post, I think.
