[ovs-discuss] 答复: 【seeking help】port-added error && openflow-port Number error

[shenwei (G)]

Hi Ben,

As below ,I have got more details about the problem.
 
1\ the total number of ports added to OVS bridge successfully is fixed. only when deleted one port(using ovs-vsctl del-port bridge_1 group11_0),another port could be added.
2\ when I set the veth interfaces as internal mode (ovs-vsctl set Interface group12_0 type=internal),all the ports can be added to the OVS bridge successfully. but openflow port number can`t be created at this time.

Best regards
Wei Shen

Hi Ben,
Thank you very much for your reply!


>>such as running two ovs-vswitchd processes at once, or removing and reinserting the OVS kernel module while ovs-vswitchd is running.
  How to confirm if there are two ovs-vswitchd processes running at once ?

>> or removing and reinserting the OVS kernel module while ovs-vswitchd is running.
  Before reinserting a new ovs kernel module(using insmod openvswitch.ko) every time ,I just rmmoded the openvswitch.ko first.Is this right?
  How to stop the running ovs-vswitchd? 

Look forward to your reply again.

Best regards.
Wei Shen

That is a very strange error.  It indicates something pretty seriously wrong.  I don't have a good guess as to what, though, because this is the first time I've seen this error reported.  It makes me wonder whether you did something really odd, such as running two ovs-vswitchd processes at once, or removing and reinserting the OVS kernel module while ovs-vswitchd is running.
