I've written a Nagios-Plugin for XEN, which throws CPU, IO, Traffic,
Uptime etc to be continued, which satisfys my need.
Should be no Problem to adopt this for rrd-graphing.
Interested? Could PM this to you :-)

hmpf? i used xm top....
TIME=`sudo xm list | grep $DOM | awk '{ print $6/60 }'`
CPU=`sudo xentop -b -i 1 | grep $DOM | awk '{print $4 }'`
VCPU=`sudo xm list | grep $DOM | awk '{print $4}'`
VBD=`sudo xentop -b -i 1 | grep $DOM | awk '{print $13}'`
MEM=`sudo xm list | grep $DOM | awk '{print $3}'`
TRAFF_IN=`sudo xentop -b -i 1 | grep $DOM | awk '{printf "%.2f",
$11/1024}'`
TRAFF_OUT=`sudo xentop -b -i 1 | grep $DOM | awk '{printf "%.2f"
, $12/1024}'`
TRAFF=`sudo xentop -b -i 1 | grep $DOM | awk '{ printf "%.2f", (
$11+$12)/1024 }'`
and so on....
