[CentOS] Switch to measure traffic at IP level?

I think I have a solution:
 
In the guests' XML files, I set a target device name
so they will always use a known device (Instead of 
getting an aribtrary vnet* device).
 
Next, using snmp on the host, I can get the interface stats
for that device and use cacti to graph it.
 
Thanks to everyone for the help,
    Neil
