Thanks a lot Numan! I did some research on ovsdbapp and found:
www.flaviof.com www.flaviof.com which allowed me to write fully working script.

Hi MailingList!
I'm trying to write Python script using OVS library to fetch DB content
and print all current bridges, ports and interfaces. Following snippet shows
what I deduced so far from examples found in mail.openvswitch.org
mail.openvswitch.org
```
import ovs.db.idl
import ovs.poller
SCHEMA_PATH = "/usr/share/openvswitch/vswitc
SOCKET_PATH = 'punix:/run/openvswitch/db.soc
schema_helper = ovs.db.idl.SchemaHelper(SCHEMA
schema_helper.register_columns
"Bridge", ["name", "ports"]
)
schema_helper.register_columns
"Port", ["name", "interfaces"]
)
schema_helper.register_columns
"Interface", []
)
idl = ovs.db.idl.Idl(SOCKET_PATH, schema_helper)
while not idl.run():
poller = ovs.poller.Poller()
print('Seqno value {}'.format(idl.change_seqno))
idl.wait(poller)
poller.block()
```
As I understand idl.run() should return `True` after DB content was fetched.
In my case this loop is infinite - seqno doesn't change. There is no error
though.
I checked listing OVS resources using cli for version:
Seems to me you are doing something wrong.
You can refer this file
github.com github.com
which tests the OVS python idl code.
There is this ovsdbapp python library which internally uses the ovs
python idl if you are interested to look into -
github.com github.com
Thanks
Numan
ovs-vsctl (Open vSwitch) 2.9.5
DB Schema 7.15.1
and those commands worked perfectly fine.
Has anyone encountered similar issue?
Regards,
MK
