Hi Jesse,

Thanks for your reply. Actually I am looking at the ovs-vsctl source these 
days. I have a few questions at hand:

One is about the ovsdb related operations. I know one of the advantages of 
openvswitch is that the ovs database can record the the network configuration, 
making it easy for migration, however, for the purpose of our project, we want 
to utilize openvswitch mainly because it supports openflow, I just don't know 
whether the ovsdb related stuff is still necessary here. 

The other one is that I want the openvswitch bridge can start forward packets 
immediately after it is created. I look at the source code, it seems that the 
default forward delay is 11 seconds and the forward delay can only be set 
within the range from 4-30 seconds. How can I set it to be 0 (otherwise, DHCP 
cannot work for my application). Or should I just disable stp?

Thanks a lot.
