I had to rebuild a host. I first removed it from Ovirt then reinstalled the OS.
I then used the same 192.xxx.xxx.207 IP as the old host. I then added it to
Ovirt which seem to go OK. However I am seeing lots of ovn errors complaining
that there was an existing port for the same IP
Port ovn-47cc88-0 new port is ovn-af7f78-0

I can bring the host 192.xxx.xxx.107 down and the errors stop on the other
hosts but ovn still has a port defined for 192.xxx.xxx.207 The question I have
is how do I delete the old port definition ?

Kevin
