Hi, Deni
You can make a connection by instantiating OVSBridge:
ovs_bridge = OVSBridge(None, datapath.id, 'tcp:127.0.0.1:6632',
timeout=1)
And by the following code, for example, you can delete a port:
ovs_bridge = OVSBridge(None, datapath.id, 'tcp:127.0.0.1:6632',
timeout=1)
ovs_bridge.init()
ports = ovs_bridge.get_port_name_list()
ovs_bridge.del_port(ports[0])
OVSBridge provides some other APIs.
For details, please check this code:

Hi, Deni
The problem may be caused by that you use "ovsdb_event" and
"ovs_vsctl" at the same time.
If you don't need to monitor the status of OVS, you should not use
"ovsdb_event".
Is it mean I should not use initiation :
"ovsdb_event.EventNewOVSDBConnection)"? So how I will make (realize) a
connection between controller and OVSDB Server?
Also, you can use "OVSBridge" to control your OVS.
"OVSBridge" calls "ovs_vsctl.VSCtl()" in __init__(), and wraps
some operations including adding a port.
Thank you for your suggestion.Would you mind to give me some clue for
using the "OVSBridge" and for calling the "ovs_vsctl.VSCtl()"?
Thanks,
Fujimoto
Thank you.

Dear all,
Currently, I am trying to make a connection between Ryu
Controller and OVS, and trying to modify OVS from controller (add
bridge, add port, delete port, etc) dynamically.
Currently, the OVS and Ryu controller can be connected. They are
running in different VM. However, when I try to run my simple
app, it didn't work. In the code, I am trying to delete one port
that I have already set up from OVS terminal. I always got this
in controller:

For your information, I customize the code and I put it in
attachment. Please give some hints for doing this, especially
with the code. Thank you.
