I had to make my own based on the hosts cgroups info. I feed the data to 
mrtg to plot cpu and IO graphs. No network though.

I run something like this on each hypervisor periodically via mrtg:

vms=`find /cgroup/blkio/libvirt/qemu/ -maxdepth 1 -mindepth 1 -type d 
-printf "%f\n"`
IGNORED_REGEX="ignore"
for vm in $vms
do
         (
         echo -n "$HOST:$vm:"
         egrep -v "$IGNORED_REGEX" 
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_serviced | grep 
^253:.*Read | cut -f3 -d " " | paste -sd+ | bc
         echo -n ":"
         egrep -v "$IGNORED_REGEX" 
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_serviced | grep 
^253:.*Write | cut -f3 -d " " | paste -sd+ | bc
         echo -n ":"
         egrep -v "$IGNORED_REGEX" 
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_service_bytes | grep 
^253:.*Read | cut -f3 -d " " | paste -sd+ | bc
         echo -n ":"
         egrep -v "$IGNORED_REGEX" 
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_service_bytes | grep 
^253:.*Write | cut -f3 -d " " | paste -sd+ | bc
         echo -n ":"
         cat /cgroup/cpuacct/libvirt/qemu/$vm/cpuacct.usage
         ) | tr -d '\n'
         echo ""
done
