Hi Dominik,
yes I was looking for those settings.
I have added again the external provider , but I guess the mess is even bigger as I made
some stupid decisions (like removing 2 port groups :) without knowing what I'm doing)
.Sadly I can't remove all packages on the engine and hosts and reinstall them from
scratch.
Pip fails to install the openstacksdk (centOS7 is not great for such tasks) on the engine
and my lack of knowledge in OVN makes it even more difficult.
So the symptoms are that 2 machines can communicate with each other only if they are on
the same host ,while on separate - no communications is happening.
How I created the network via UI:
1. Networks - new 2. Fill in the name3. Create on external provider4. Network Port
security -> disabled (even undefined does not work)5.Connect to physical network ->
ovirtmgmt
I would be happy to learn more about OVN and thus I would like to make it work.
Here is some info from the engine:
[root@engine ~]# ovn-nbctl showswitch 1288ed26-471c-4bc2-8a7d-4531f306f44c
(ovirt-pxelan-2a88b2e0-d04b-4196-ad50-074501e4ed08) port

Is it possible to remove the vNICs , Virtual Network + and recreate the ovn db to start
over ?I guess the other option is to create a VM that can be used to install python
openstacksdk and modify via the python script from your previous e-mail.

Hi Dominik, All,
I've checked
'https://lists.ovirt.org/archives/list/users@ovirt.org/thread/W6U4XJHNMYMD3WIXDCPGOXLW6DFMCYIM/'
and the user managed to clear up and start over.
I have removed the ovn-external-provider from UI, but I forgot to copy the data from the
fields.
Do you know any refference guide (or any tips & tricks) for adding OVN ?
The ovirt-provider-ovn entity can be added to oVirt Engine as a new provider withType:
External Network ProviderNetwork Plugin: oVirt Network Provider for OVNProvider URL:
https://YOUR_ENGINE_FQDNt:9696
Username: admin@internalPassword: admin@interal passwordHost Name: YOUR_ENGINE_FQDNAPI
Port: 35357API Version: v2.0
Is this the information you need?
Thanks in advance.
Best Regards,

Hi Dominik,
Thanks for the reply.
Sadly the openstack module is missing on the engine and I have to figure it out.
Can't I just undeploy the ovn and then redeploy it back ?

The cleanest way to clean up is to remove all entities on the OpenStack Network API on
ovirt-provider-ovn, e.g. by something like

This should work, if not, please report a bug.
To bypass the ovirt-provider-ovn, which is not recommended and might end in an
inconsistent state, you could use ovn-nbctl .

Hi Community,
can someone hint me how to get rid of some ports? I just want to 'reset' my ovn

Here is what I have so far:

When I try to remove a port - it never ends (just hanging):
[root@ovirt1 openvswitch]# ovs-vsctl --dry-run del-port br-int ovn-25cc77-0
In journal I see only this:дек 12 04:13:57 ovirt1.localdomain ovs-vsctl[22030]:
ovs|00001|vsctl|INFO|Called as ovs-vsctl --dry-run del-port br-int ovn-25cc77-0
The stranger part to me is the log output:

I'm also attaching the verbose output of the dryrun.
