<div style="word-wrap:break-word"><div class="im">Hi,
<div><br>
</div>
<div>I'm currently wondering how to setup OpenStack without floating ips in a multi host setup.</div>
<div><br>
</div>
<div>Like outlined in the Operations Manual, Chapter 6. Network Design, „Fixed IP addresses can be private for private clouds, or public for public clouds.“ [1]</div>
<div><br>
</div>
<div>So you can easily create a publicly routable network and have VMs automatically allocate a single address from within this range.</div>
<div>If you have more than one compute node they need to be within the same physical network - regardless of wether you are using multi host or a single networking node (nova-network or quantum).</div>
<div><br>
</div>
<div>If you define more than one fixed network, you'll end up with „multinic“ [2]. </div>
<div>So it seems that's not possible to bind a specific fixed network to a compute node.</div>
<div><br>
</div>
<div><br>
</div>
<div>My question is… how do you avoid activating multinic and associate a fixed network with a specific compute node?</div>
