  The vif interface itself is not indicative of a bridge.

  Whether you have a bridge or not depends upon how your Xen
 installation is setup.  If you look at /etc/xen/xend-config.sxp
 you'll see that you have several choices for the two settings
 "network-script" + "vif-script".  These two settings are designed
 to work together.
 
  Available choices include:

    (network-script network-bridge)
    (vif-script     vif-bridge)

   or

    (network-script network-route)
    (vif-script     vif-route)

   or

    (network-script network-nat)
    (vif-script     vif-nat)

  If you use the first of these settings, network-bridge/vif-bridge,
 you'll have a bridge-based network.

  If you use either "network-route" or "network-nat" you will not.

  This is explained in the Xen networking documentation, as well
 as in the documentation contained withing the xend-config.sxp file
 itself.

  If you have a need you can create your own network setup and 
 use those instead, again choosing for yourself wheter to bridge
 or not.
