[ovs-discuss] How to create a public bridge in openVswitch for KVM virtual instances?

[Yueyu Lin]

Hello everyone,
     I'm very new to open vswitch. The question is simple but I googled a lot and resulted in no results.
     From the document INSTALL.KVM, I can install a virtual machine. In the VM, I can find the device by lshw and since the br0 doesn't actually connect to the real network, the eth1 can't be set a real address and access network. From the Linux distros, we can always use brctl,ifconfig and other tools to connect the bridge to the real network. How can I do using the open vswitch's utility? No related documentation is found after a long time search. 
     Thanks in advance.
