Setup:

i follow the main instruction for deploying openstack for learning purposes.

I can successfully deploy vms in an internal network, and also connect them to a router that gives internet access using floating ips etc.

My setup is based on ubuntu 18. I have virtualbox for deploying controller (10.0.0.11) and compute (10.0.0.31) etc.

I have host only adapters at virtual box (dhcp enabled) for the two networks: mgmt: 10.0.0.0/24 and provider 203.0.111.0/24 as per the default instructions, and i use iptables to NAT the vms.

Problem:

When following the instructions from https://docs.openstack.org/install-guide/launch-instance-provider.html the vm is deployed successfully but the ip that it is assigned is different from the one that the controller has.

It seems that there are more than one dhcp instances running? How can i debug this?

Any advice?

all the best,

Pavlos.
