Comment 1 for bug 1866139

So more I think about it, in Floating IP/route case, it sends from the fip ns because 1. the host has access to it and 2. the FIP is configured on it fip gateway port. And DVR qrouter updates static ARP entries for east-west routing.

In a provider network, there is no IP configured on the host. It's a pure L2 port that passes thru OVS (a pure L2 switch), and into the VM. OVS does not deal with IPs. the tap and qvo ports don't have an IP configured in them

From what interface would the GARP even be sent out?

[root@arjunlive-10-128-242-125platform9 ~]# arping -U -I tapdb8f8ab2-1f -c 3 10.128.138.119
bind: Cannot assign requested address

Does this mean its intended behavior and live migration isnt possible without network loss, for provider nets/isolated tenant networks?
