Hi all,

I've been trying to deploy OPNFV using Fuel.

I followed the installation instructions present in the website step by step and everything worked fine up to step 7.10, where I have to run the connectivity check, then I get the following error:

Node <controller-hostname> discovered DHCP server via enp2s0f0 with following parameters: IP: 10.0.1.1, MAC: XX:XX:XX:XX:XX:XX. This server will conflict with the installation.

Node <compute1-hostname> discovered DHCP server via enp2s0f0 with following parameters: IP: 10.0.1.1, MAC: XX:XX:XX:XX:XX:XX. This server will conflict with the installation.

Node <compute2-hostname> discovered DHCP server via enp3s0f0 with following parameters: IP: 10.0.1.1, MAC: XX:XX:XX:XX:XX:XX. This server will conflict with the installation.

During Fuel master node installation I configured the DHCP pool range for PXE to be 10.0.1.X, which I assumed that would be the "admin" network used by fuel to communicate to slaves. Fuel is able to discover the slave nodes normally.

All the other networks used in the setup (storage, public, private, mgmt) do not overlap with 10.0.1.0/24).

Diagram of my setup.

Why am I getting this error now? Any thoughts?

Thank you very much.
