Ignazio, The Neutron DHCP agent only hands out leases to devices/instances managed by Openstack. Unlike nova-network, hypervisors do not get an IP out of Neutron networks. Is there a particular reason you'd want to do this?

Dhcp release addresses to openstack virtual machines but not to physical hosts in the same network. If I assign an address to the physical host I can ping the neutron dhcp server. Could anyone help me ? Regards -------------- next part -------------- An HTML attachment was scrubbed...
