I would like to configure the nova-network in single-host mode. I found this manual https://www.mirantis.com/blog/openstack-networking-single-host-flatdhcpmanager/ (https://www.mirantis.com/blog/opensta...) . But it is not complete. Is there a complete manual on this topic?
Why is this instruction service dnsmasq is running before you run the instance? I run it after you run the instance and the bridge appears after instance startup.

Not single node. Single-host. Multi-host is when each compute node runs a copy of nova-network and the instances on that compute node use the compute node as a gateway to the Internet. Single-host is when a central server—for example, the cloud controller—runs the nova-network service.
