/me guesses there are no pre-built spice packages for your linux system, 
so you have to build spice yourself.  In short:

   * Fetch, build + install celt, version 0.5.1 is needed.
   * Fetch, build + install spice-protocol
   * Fetch, build + install spice

You can download the bits from:

   http://www.celt-codec.org/
   http://www.spice-space.org/

With this in place you should be able to build qemu with spice support 
(configure should detect it).

The add '-spice port=$number,disable-ticketing' to your qemu command 
line.  Start spice client (part of the spice package) this way:

   spicec -h localhost -p $number

Note that spice doesn't work (yet) on bigendian machines, so don't try 
that on your ppc box.
