Quantum Server, DHCP agent, and Metadata agent do not have to run on the same host #27

Quantum Server, DHCP agent, and Metadata agent do not have to run on the same host. Does midonet metadata integration code support those components running on different hosts?

ryu25ish commented 11 years ago

Currently it is required that metadata agent and DHCP agent run on the same host, and that pat of the code is handled by Neutron, not the plugin. The Neutron server, however, could run on a separate host. Is there any reason why we want to separate DHCP agent and metadata agent?

admytren commented 11 years ago

I don't know of any good reason, just that it is theoretically possible. So there is no requirement for neutron to run on the same host as DHCP/metadata agent? Or all three must run on the same host. I think we would want to document this limitation clearly in our deployment guide.

Neutron server could definitely run on a different host from DHCP/metadata agent. In fact, it probably should be. What I was saying in the earlier post was that DHCP agent and metadata agent must run on the same host.

Cool! Thanks for the clarification Ryu!
