I have got one question on this. Does quantum directly request leases from the gateway of the physical network before reserving them to allocate to VMs?
Nope, not at all. It's up to the administrator to make sure the IP ranges for Openstack are not pooled by any other DHCP server. There is (as per my knowledge) no way to sync up in between quantum-l3-agent and other DHCP servers.
Actually, contrary to fixed ip networks in Quantum, floating IP networks are not DHCP managed. Eligibility is made upon next IP address available in Quantum mysql database and directly injected into iptables, that's it.
