RHEV 3.1 does not yet support native spice smartcard remoting but it should be integrated quite soon.

If you can not wait, you could use it with 3.1 if you:
  * install smartcard hook on the host and enable it
  * use something on top of rest api that will launch the client with smartcard option enabled.
    (spice-xpi also has the same knob too: 'document.getElementById("<your spice-xpi object ID>").Smartcard = true;' it is false by default).
