Hi, Salman.  There are a few OpenStack/Quantum people on this list, but I 
suspect you'll have better luck on the main OpenStack list:

openst...@lists.launchpad.net

 Hi All,
 
 I am trying to learn the functionality of Quantum plugins used in OpenStack. 
 I have read through the Quantum Admin Guide and had few basic/quick question 
 about quantum and OVS interaction with it :
 
 
 1) OVS can have ports in which vNICS can be plugged, so why does it need to 
 use an integration bridge for connecting all VMs on the same node to a 
 network?
 
 2) The OVS quantum plugin seems to implement the core API functions and 
 (viewing the code) I concluded that it just makes maintains the logical 
 mappings e.g. b/w net IDs and VLAN IDs in a database. So how is this mapping 
 implemented on the actual ports of OVS? Is it the OVS quantum agent 
 responsible for directing the packets to correct input/output ports based on 
 the updates that it gets from the database?
 
 3) The quantum admin guide says that the nova client will be the main user of 
 quantum and will interact with it via REST API, so it would be nice if 
 someone can point me to the code (file path name etc.) where this happens.
 
 Thanks,
 Salman
 
 PS: What is the purpose of Quantum Manager in this architecture and where 
 should I look for its code?

Thanks Justin. I have posted the questions there as well, but since most of the 
questions are related to OVS I thought people here can also help me understand 
its functionality.

Thanks,
Salman
