Personally I use several static tapN interfaces.
This can be used to set the equivalent of a loopback interface (one
different tap0/tap1/... per vserver) or to set an internal private
network between vservers.
For info this trick came from the time I was playing with UML (user-mode
linux).
But maybe it could solve your problem.
Note that the host will see all tap interfaces as the host creates all
those tap.
