There are several options for the dedicated NIC

 - Use <hostdev mode="capabilities" type="net">

   http://libvirt.org/formatdomain.html#elementsHostDevCaps

   This simply moves the host NIC into the container's network
   namespace, making it invisible to the host, and only usable
   by that one container

 - Use <interface type="direct">

   http://libvirt.org/formatdomain.html#elementsNICSDirect

   This connects the host NIC to a container via macvlan
   device.  This can also be used for the shared NICs.
