Bridged network no traffic

I’ve succesfully deployed a test environment for ONE. So far I like it, but one piece I’m missing - internet connectivity on my VM’s.

I’ve setup bridged networking:

[root@one one]# onevnet show 1

VIRTUAL ROUTERS

I see the bridge active on the node:

[root@hv1 ~]# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.9e116f4461fc       no              bond0.302
one             8000.9e116f4461fc       no              bond0
                                                        one-7-0

All in all it looks fine to me, but I get no traffic in or out from the VM itself. I must be overlooking something pretty obvious…
Also - when I manually assign an IP to the bridge there are no issues, works like a charm.
