[openstack-community] Ovn chassis error possibly networking config error.

 Thanks for your reply much appreciated, deployed OpenStack through JUJU.
I managed to get around that issue by restarting services but I have fallen into another issue now, looks like I need to define network time somewhere on the config I am right?
When I create a network trying to get out a second interface I am getting errors. Any suggestions, please?
labuser at maas:~/openstack-base$ openstack network create Pub_Net1 --external --share --default --provider-network-type vlan --provider-segment 201 --provider-physical-network externalError while executing the command: BadRequestException: 400, Invalid input for operation: physical_network 'external' unknown for VLAN provider network.
The first network segment  is ok

labuser at maas:~/openstack-base$ openstack network create Pub_Net --external --share --default \   --provider-network-type vlan --provider-segment 200 --provider-physical-network physnet1

What did you use to deploy OpenStack ? Based on the command below I
don't recognize that output.

>> Then deployed and configured VM instance with networking but config onv-chassis is reporting error, as I am new to openstack (having used it number of years back) mind guiding where I should be looking any help will be greatly appreciated.

I do not recognize this output or that error in particular, but I
assume that ovn-chassis is the name of the process of the
ovn-controller running on the node ?

If so, the configuration of ovn-controller should be present in the
local OVSDB instance, can you please paste the output of the following

$ sudo ovs-vsctl list Open_VSwitch .

Also, do you have any logs related to that process ?
