Sure, that's for XEN, but it's not very effective. I need graph the traffic
for each VM, not the vif - the vifs tend to change on a reboot, and also
reset with the stats.

How can I graph the traffic over a perioud of time, for any given IP

Cacti works well, for switches & routers, but I can't get Cacti to graph an
individual VM on the server.
