No, I haven't turned on the PROMISC bit on the OVS bridge, nor the tap0
interface used by the guest.
I can give it a try.

Is the PROMISC bit turned-on on the bridge? I've seen that cause DUP-ed frames
on the Linux bridge, don't know about OVS however.

Maybe no difference then, I've never used openvpn to create non-vpn tap
interfaces (but it looks like your command does the same thing). I've used
tunctl and started kvm hosts with them and attached them to openvswitch
without a problem.
That said I haven't really used userspace OVS. Best bet is t
No, still the ping DUP problem is there. Is there difference between the
tap0 created by tunctl and openvpn? Or in your configuration tunctl is
adopted?

As a blind guess does this change anything (Using tunctl over your openvpn
command)?
ovs-vsctl del-port br0 tap0
tunctl -d tap0
tunctl
ovs-vsctl add-port br0 tap0
Restart vm using the new tap0

The evidence points to a configuration error, since plenty of other
users do not see duplicate packets in similar situations. Again I
suggest that you read REPORTING-BUGS and provide the information
suggested there.

Hi, Ben,
In the last few days, I have spent my spare time on figuring out the reason
of ping DUP problem. Here is my result:
The network setting including netmask\default gateway etc. contains no
error. Following is the ip address setting and routing table of the host
and the guest:

I don't see how br0 and eth0 having the same MAC address would cause the
behavior that you mention. I would suggest following a conventional
troubleshooting procedure instead of making this assumption.
If you want us to help with that troubleshooting then you can start from
the suggestions in REP
Thanks, Ben,
But there is a problem here. The following commands have not changed:
sudo ovs-vsctl add-br br0
sudo ovs-vsctl set bridge br0 datapath_type=netdev
sudo ovs-vsctl add-port br0 eth0
sudo ovs-vsctl add-port br0 tap0

Hi, everyone,
I have installed OVS userspace program on Ubuntu Oneiric according to
INSTALL.Linux. Then I have added a bridge using following commands:
sudo ovs-vsctl add-br br0
sudo ovs-vsctl set bridge br0 datapath_type=netdev
sudo ovs-vsctl add-port br0 eth0
sudo ovs-vsctl add-port br0 tap0
