Anyone?

Could I ask some people to try running this script on their non-loaded
dom0 and see what it returns?

x=$(cat /proc/stat | grep cpu0 | awk '{print $5}') && sleep 60 &&
y=$(cat /proc/stat | grep cpu0 | awk '{print $5}') && echo -e
"X:$x\nY:$y\nIDLE:" $(echo "scale=3; ($y-$x)/6000*100" | bc)

The Idle output should close to 100% per cpu in the dom0.
