Hi,
<div><br>
</div>
<div>thanks for your answer. But that does not solve my problem when I'm in different data centers.</div>
<div><br>
</div>
<div><br>
</div>
<div>Here's an example:</div>
<div><br>
</div>
<div><br>
</div>
<div>1.</div>
<div>Compute Node A (Germany)</div>
<div>Public Network for VMs: 12.34.100.240/28</div>
<div><br>
</div>
<div># nova-manage network create --label node-A --fixed_range_v4 12.34.100.240/28 --num_networks 1 --network_size 16 --vlan 100 --bridge br100 --bridge_interface eth0 --multi_host T</div>
<div>
<div><br>
</div>
<div><br>
</div>
<div>2.</div>
<div>Compute Node B (USA)</div>
</div>
<div>Public Network for VMs: 88.99.155.240/28</div>
<div><br>
</div>
<div># nova-manage network create --label node-B --fixed_range_v4 88.99.155.240/28 --num_networks 1 --network_size 16 --vlan 101 --bridge br101 --bridge_interface eth0 --multi_host T</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Alright… now I've two networks defined:</div>
<div><br>
</div>
<div>
<div># nova-manage network list</div>

</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Now I want to start a VM on Compute Node A in Germany – but I gets two ip addresses. One of each network. That's not what I want.</div>
<div><br>
</div>
<div>So I tried assigning a network to a specific host:</div>
<div><br>
</div>
<div># nova-manage network modify --host=node-A 12.34.100.240/28</div>
<div># nova-manage network modify --host=node-B 88.99.155.240/28 </div>
<div><br>
</div>
<div><br>
</div>
<div>But that has no effect...</div>
<div><br>
</div>
<div><br>
</div>
<div>Here's my config:</div>
<div><br>
</div>
<div># Network<br>
network_manager=nova.network.manager.VlanManager<br>
firewall_driver=nova.virt.libvirt.firewall.IptablesFirewallDriver<br>
multi_host=True<br>
<br>
dhcpbridge=/usr/bin/nova-dhcpbridge<br>
dhcpbridge_flagfile=/etc/nova/nova.conf<br>
force_dhcp_release=True</div>
<div><br>
</div>
<div><br>

<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>
<div><br>
