[ovirt-users] Replaced host but ovn complains of duplicate port
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 ?
