there is one thing I noticed below:

Here you did not add any physical interface (eth0 or eth1).

But here, the br0 is assigned with eth0's original ip and mac address.
It seems to me that you just did
"ovs-vsctl del-port eth0"
"ovs-vsctl del-port eth1"
But you didn't reset the address.
With your configuration, you should reset the br0's address to 0.
Or you should try creating the br0 and configure it again.
Another useful command for debugging is the "ovs-appctl dpif/dump-flows
[bridge_name]" command
It prints out good info about kernel flows (how the kernel will handle the
packet)
