What's more, the steps I followed is from the openvswitch FAQ document in http://docs.openvswitch.org/en/latest/faq/issues/
But even follow these steps, every time I need to reconfigure the bridge interface such as br0's ip address etc ...
Common Configuration Issues - Open vSwitch Documentation<http://docs.openvswitch.org/en/latest/faq/issues/>
A: More than likely, you’ve looped your network. Probably, eth0 and eth1 are connected to the same physical Ethernet switch. This yields a scenario where OVS receives a broadcast packet on eth0 and sends it out on eth1, then the physical switch connected to eth1 sends the packet back on eth0, and so on forever.
Q: I can’t unload the openvswitch kernel module. Why?
A: The userspace might still hold the reference count. So rmmod openvswitch does not work, for example:
$ lsmod | grep openvswitch
openvswitch 155648 4
nf_conncount 24576 1 openvswitch
Use the command below to drop the refcnt:
$ ovs-dpctl del-dp system at ovs-system
$ rmmod openvswitch

主题: [ovs-discuss] replace the openvswitch.ko without losing the bridge interface's configuration
When I replace the openvswitch.ko with a new modified one, the configuration on the bridge such as br0 is lost. I need to reconfigure its ip address and bring it up again manually.
Is there any alternative that we could replace the openvswitch.ko without losing the bridge interfaces’ configuration?
The steps I used to replace the openvswitch on the centos.
1) Compile the openvswitch
make -j `nproc`
2) Replace the openvswitch.ko
ovs-dpctl del-dp system at ovs-system
