Fix for AMD reset bug?
Potential fix for AMD reset bug
Keep in mind I haven't yet tested this
Hookscript example:
#!/bin/bash
if [ $2 == "pre-start" ]
then
echo "gpu-hookscript: Resetting GPU for Vitual Machine $1"
echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
echo 1 > /sys/bus/pci/rescan
fi
Note: you have to change the device id to match yours
Then deploy it:
#create snippets folder
mkdir /var/lib/vz/snippets
#create script with content above
nano /var/lib/vz/snippets/gpu-hookscript.sh
#make it executable
chmod +x /var/lib/vz/snippets/gpu-hookscript.sh
#apply script to VM
qm set 100 --hookscript local:snippets/gpu-hookscript.sh
