I have my local internal subnet of, which is what my router will assign physical machines on my network an address from. I have setup another subnet for my OpenStack instances, here:

gnychis@src-server1:~$ nova network-list
| ID                                   | Label         | Cidr          |
| fb655e7d-7824-4134-b0dc-e105a50e9326 | soroco-os-net | |

Whenever I boot a Windows 7 instance fresh, it automatically gets assigned an IP within the local internal subnet (, however no traffic seems to flow to/from it (it's being filtered?). This is incorrect, it should be assigned an IP address in

This is despite OpenStack showing it has a floating IP address of

Inspecting Wireshark traces it asks for but it gets a NACK "wrong address" back over the network:

If I open up command prompt and run ipconfig -release followed by ipconfig /renew it gets its proper IP address assigned:

I can't seem to figure out how to have it assigned the proper IP address in the first place. I am using nova-network.

Here is my full nova.conf

id      IPv4                    IPv6            start address   DNS1            DNS2            VlanID          project         uuid
5           None           None            None            None            fb655e7d-7824-4134-b0dc-e105a50e9326

Check the bridge interface when you created the network in nova. Better yet why don't you share your nova.conf so people can help you check.

Can you paste the result of nova-manage network list and Is this a multi-node setup?

added it to my question! I have 2 nodes, one which is the controller and networking node, and another which is just a compute node
