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 ?
Thanks in advance.
Best Regards,

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 ovirt-provider-ovn entity can be added to oVirt Engine as a new
provider with
Type: External Network Provider
Network Plugin: oVirt Network Provider for OVN
Provider URL: https://YOUR_ENGINE_FQDNt:9696
Username: admin@internal

Host Name: YOUR_ENGINE_FQDN

New subject: Ovirt OVN help needed
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.

New subject: Ovirt OVN help needed

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.
This indicates that the tunnels between the hosts are not created.
Can you please check the /var/log/openvswitch/ovn-controller.log on both
hosts for errors and warnings, or share parts of the files here?
If this does not point us to a problem, ovn has to be reconfigured. If
possible, most easy way to do this would be to ensure that
ovirt-provider-ovn is the default network provider of the cluster of the
hosts, put one host after another in maintance mode and reinstall.
How I created the network via UI:
1. Networks - new
2. Fill in the name
3. Create on external provider
4. 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 show
switch 1288ed26-471c-4bc2-8a7d-4531f306f44c

Is it possible to remove the vNICs , Virtual Network + and recreate the
ovn db to start over ?
@Miguel Duarte de Mora Barroso <mdbarroso(a)redhat.com> Is there a hardcore
way bypassing ovirt-provider-ovn to do this?
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.
Yes, a fedora VM in oVirt works great and creating a template from the
images from ovirt-image-repository is comfortable.

Hi Dominik, All,
I've checked '
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/W6U4XJHNMYMD...
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 with
Type: External Network Provider
Network Plugin: oVirt Network Provider for OVN
Provider URL: https://YOUR_ENGINE_FQDNt:9696
Username: admin@internal
Password: admin@interal password
Host Name: YOUR_ENGINE_FQDN
API Port: 35357
API Version: v2.0
Is this the information you need?
Thanks in advance.

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
https://gist.github.com/dominikholler/19bcdc5f14f42ab5f069086fd2ff5e37#fi...
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 .
