I do not understand this.

You can attach a physical (or virtual, doesn't matter), interface to any
given vm, without assigning routes or IPs to these interfaces directly.

Just do the network configuration inside the vm, and the routing, well
on your router? You will just need the route for the vm networks on your
host, but what is your attack scenario to keep this separated from other
routes on this host? you need at least CAP_NET_ADMIN to fiddle with those.
