That scheme in my case would not work. I have two interfaces inside the container, and each one talks to a different network, for business reasons. I use policy-based-routing to make sure that packets go to the right places. I need that the container can hold a full configuration. In my case, I use ifupdown, not netplan, since my containers are for an older version of Debian. It is "not right" that ipvlan does not work out-of-the-box like macvlan or veth. Somebody has to fix it. I cannot use macvlan because Vmware only allows multiple macs if the entire network is set in promiscuous mode, and that kills performance. So basically the only workaround is ipvlan. As I said, if you use type=phys and ipvlan inside the host, it works fine, without altering the container.
