pure-ovn: same ip address in multiple containers? about ovn-scale-test HOT 3 CLOSED

heh, it looks like I'm missing on some caveat related to the ip stack here. Let me get back to my docker docs... I can clearly see that the "ip a" command in the host system is giving me the same exact value, so this is not a per container scoped. Sorry!

vagrant@pureovn:~$ ip a

@flavio-fernandes is this still an issue or can we close this? Thanks.
