I have a question about Quantum set-up. I follow the instruction described in to set up the quantum. In this manual, only network node supports DHCP function. My question is does Quantum support Multi-host Mode like nova-network? Could every compute node has one DHCP agent? Currently it seems to me that almost all the function is realized in network node. Thanks a lot.

"No equivalent for nova-network --multi_host flag: Nova-network has a model where the L3, NAT, and DHCP processing happen on the compute node itself, rather than a dedicated networking node. OpenStack Networking now support running multiple l3-agent and dhcp-agents with load being split across those agents, but the tight coupling of that scheduling with the location of the VM is not supported in Grizzly. The Havana release is expected to include an exact replacement for the --multi_host flag in nova-network."
