I apologize if I keep asking questions about the OpenStack Nova Compute Hyperv driver, I'm a newbie

I've managed to configure Neutron to use Hyper-V but when I try to start the services with

/bin/neutron-server --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/plugins/ml2/ml2_conf.ini

At the bottom of the log I find this error that I don't understand how to fix:

RuntimeError: Unable to load neutron from configuration file /etc/neutron/api-paste.ini.

the neutron-server service fails to start while if I remove "hyperv" from mechanism_drivers everything is resolved the service starts but still I am not able to start instances with Binding for Port Failed,

I also installed the networking_hyperv package with pip but it doesn't seem to do anything, I'm on OpenStack Legacy Liberty

Openstack Liberty was released in 2015, it was discontinued a long time ago.

Also, we've announced that we'd no longer support Openstack on Windows in November [1], in the meantime it was officially retired [2].

That being considered, I strongly suggest switching to a recent Openstack release [3] and use a supported hypervisor (e.g. KVM).
