Hello Guru,

I think OVS doesn't like me at all :) every step I am facing a issue.

this time when I tried to create a docker network on OVS (*sudo docker
network create -d openvswitch --subnet=192.168.22.0/24
<http://192.168.22.0/24> ovs*) it failed and I got this error in Docker log

*ERRO[2717] Handler for POST /v1.27/networks/create returned error:
remote: create_network: lswitch-add Fatal error executing
['ovn-nbctl', '--timeout=5', '-vconsole:off',
'--db=tcp:192.168.14.33:6642 <http://192.168.14.33:6642>',
'lswitch-add', u'6eccad3be08421bb50e97a620c0ffa80e28e9676e8ad18881aeb1a640d7cdd55',
