Note that the IP address you assign to the host end of the tap device
must be different than the IP you assign to the eth device inside UML.

you can reuse the host's eth IP address for the host ends of the tap
devices. Internally, the UMLs must still get unique IPs for their eth
devices. You can also give the UMLs non-routable IPs (192.168.x.x or
