Does it work if you do "ip link set host0 up" in the container? I think that would be a better

As far as the host is concerned, I think you should consider the bridge as if it were the only 
interface. The enp7s0 interface is part of the bridge and should not be configured in addition 
to being joined to the bridge. So yeah, I would get rid of the physical enp7s0 configuration, 
and leave only the bridge configuration on the host.
