I edited the script provided by @mdsloop, now he working smooth, with cron run every 2 min.

 

VMnametocheck="Windows 10 Gaming"
stateofvm=$(virsh list --all | grep "$VMnametocheck" | awk 'NF{ print $NF }')
if [[ "$stateofvm" == "running"  ||  "$stateofvm" == "idle"  ||  "$stateofvm" == "paused" ]]; then
	echo "The $VMnametocheck VM is in $stateofvm state"
else
	echo "The $VMnametocheck VM is Shutted down! And now Nvidia GPU will go to power save state P8"
	nvidia-smi -pm 1
fi

 

 

Thanks for this work !

I discover just today my graphics cards used 18W all the time even with my Windows VM shutdown. Your script work perfectly in my case !

 

Have a great day.

Old Topic but maybe someone is interested in my Code:

 

# Get the number of GPUs
num_gpus=$(nvidia-smi --query-gpu=count --format=csv,noheader | awk 'NR==1 {sum+=$1} END {print sum}')

echo "Found $num_gpus GPUs."

# Iterate over the GPUs
for ((i=0; i< $num_gpus; i++)); do
  # Check if there are any processes running on GPU $i
  if nvidia-smi -i $i --query-compute-apps=pid --format=csv,noheader | grep -q '^[0-9]'; then
    echo "There are processes running on GPU $i."
  else
    echo "There are no processes running on GPU $i. Setting GPU $i to power save mode."
    nvidia-smi -i $i -pm 1
  fi
done

 

It first checks how many GPUS are installed and then if there are running processes. If not, Power save mode will be activated.

 

This worked for me on my Tesla P4. It was stuck at 1% being used by nothing, and kept idling at 24W, 800MHz GPU, 2000MHz Mem. This fixed it!

What about AMD GPUs.. do they have this problem??
