Re: [Openstack] [Openstack :: Folsom] Quantum DHCP Agent in Compute HOST
Hi Salvatore, Just want to understand more on Network Node in the below given app_demo page. As i see in the setup, it looks like there will be one Quantum Network Node for one Data centre setup. Please correct me if my assumptions are wrong. This Quantum Network Node will have all the virtual routers, gateway which can be created with quantum-l3-agent plugin. Also my assumption is that this quantum Network Node will serve all the Tenant virtual gateways and routers created using quantum. Please give us some more information on this to understand the setup. Also do we have any specific reason for having quantum Network Node instead of keeping these plugin on the Controller Node similar to earlier release like Essex. Thanks in advance.

Re: [Openstack] [Openstack :: Folsom] Quantum DHCP Agent in Compute HOST
Hi, In fact, we can split Quantum network Node into two categories: one is for dhcp, which install ovs agent and dhcp agent. We can have one such kind of node one is for l3 agent, we can deal with one external network on one l3 agent. We can have many nodes of this kind.

Hi Trinath, Even if is perfectly reasonable to run the DHCP/L3 agents in the controller node, the advice we give in the administration guide is slightly different. As suggested in [1], the only Quantum component running on the controller node should be the API server. The DHCP and L3 agents might run in a dedicated network node. Please note you will need also the L2 agent running on that node.

Re: [Openstack] [Openstack :: Folsom] Quantum DHCP Agent in Compute HOST
Hi Salvatore- Thanks a lot for the reply. In the Setup diagram, I'm planning to make a 2 machine setup in my test environment. Where Can I have the Installation guideline for the Quantum L2 agent. Have few doubts in the Quantum DHCP agent Source Code. As I have gone through the source code, the DHCP agent runs as an RPC daemon. It places messages in the ampq. I was confused with the following code in /quantum/db/dhcp_rpc_base.py in the method: def get_network_info() plugin = manager.QuantumManager.get_plugin() To what plugin its mapping to ? Is the appropriate plugin configured in the configuration files. network = plugin.get_network(context, network_id) How do the mapping to plugin made here? Can you please help understand these...
