It would be pretty much the same configuration as your tap setup.  The Xen 
networking model is to expose a VIF ('virtual interface') in the guest and 
dom0.  Everything else from there is host setup and can be customised -- most 
commonly by adding a bridge to the outside world and adding the VIFs from the 
guests to that bridge so they can communication externally.

The xl setup fragment looks like:

    vif = [ 'bridge=xenbr0' ]
or
    vif = [ 'mac=c0:ff:ee:c0:ff:ee,bridge=br0' ]
