TC is fairly complex, and only really effectively limits speed sent.  If 
you want to limit the upload speed of a guest, you'd put the rules on 
the interface that hosts the default route for traffic from the guest.

Shorewall does a reasonably good job of dealing with most of the 
complexity of tc under Linux.
