Still can't quite sort this out but I am circling in on where the problem is.
To recap bootpc and arp requests from instances using GRE tenant
networks are not making it onto the physical network, I suspect this
is "all broadcast traffic". If IP is configured statically and the
arp cache is set

I can reproduce this. I suspect because patch-tun and patch-int are OVS
patch interfaces, they are internal to OVS and not a real interface. "ip a

I also notice ARPs are asysmetric. arp requests from the instance
don't end up on the wire, but arp requests from the network controller
do make it to the instance and the responses make it back. So once
the network controller has made contact and it's MAC is in the
instance ARP cache then things
HI All,
DHCP requests from instances with interfaces on OVS/GRE based tenant
networks are showing up on the tap device on the compute node but
never make it to the physical network device (tcpdump -i ehtX proto
gre).
If I manually configure an address all seems well & I can for example
ping from
