i am facing the same problem, after adding the ovs external interface br-ext to the ext1 (physical public interface), connection lost to the server. I have applied manual configuration whatever mention in other blogs, but still its there.

Thank you very much for your reply.

How many NICs are you using? It looks like you are adding you mgmt link to br-ex and not you public network link.

Hi Jason,

I have only 1 network card and no public network card, if this is the case then I shouldn't bridge it? can i remove the bridge?
