New subject: Ovirt OVN help needed

Thursday, 12 December 2019

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,

 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 ?

 Best Regards,
 Strahil Nikolov
