Hello Everyone,
Could you give me any advice and help me to better understand neutron. On my VirtualBox VM I properly installed Openstack using packstack (all-in-one installation). I have access to the horizon dashboard.
I'm able to launch an instance and associate floating IP but from the controller node I cannot reach my instance.
Here are my interfaces config:
enp0s3: for mgmt
enp0s8: for openstack services
enp0s9: for neutron_external_interface (used as a public interface)
enp0s10: interface on my controller to be connected to the neutron_external_interface
VirtualBox Promiscuous mode : Allow All

I couldn't find something related to the binding port in these logs file.
tail -f /var/log/neutron/openvswitch-agent.log
tail -f /var/log/neutron/server.log
tail -f /var/log/neutron/l3-agent.log
Any advise will be welcome
