I performed a cluster node installation using this guide [OpenStack Charms Deployment Guide].(https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html), where the type of network is a Flat network and the components used are:
- Maas
- Juju
- Openstack
My lab is composed by following devices:
1 IBM System 3540 M4 Maas (500GB HDD - 8GB RAM - 1 Nic)
1 IBM System 3540 M4 Juju (500GB HDD - 8GB RAM -1 Nic)
4 IBM System 3540 M4 Openstack (500GBx2 HDD - 16GB RAM - 2 Nic)
1 Palo Alto Network Firewall
Public Network 10.20.81.0/24 - Private Network 10.0.0.0/24
Maas: 10.20.81.1
Juju: 10.20.81.2

On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.
On Juju gui I've that:
neutron-gateway:
bridge-mappings: physnet1:br-ex
data-port: br-ex:eno2
neutron-api:
flat-network-providers: physnet1
I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:
error: "could not add network device eno2 to ofproto (Device or resource busy)"
Maybe that is the cause of my first issue, but I don't understand how I can fix it.
