Re: [Openstack] [openstack-dev] [Quantum] Multi-host implementation

hi, I have a question about the ip address consumed by the dhcp services. is it necessary to assign an individual ip for each dhcp daemon? can we reserve only one ip address for all dhcp deamons subject to one subnet since they won't run on the same host? since the dhcp service only need to communicate with local VM instances and local dhcp agent (don't know if it is true for this assumption), can we find a kind of isolation mechanism to avoid ip conflicts and extra consume of ip addresses to implement this feature?
