1. Are you using a full OS or a node?
2. rpm -qa |grep vdsm
3. if possible, post the hook code

Thanks

Hi,

1)  is it enough to add a hook.py in  /usr/libexec/vdsm/hooks/before_vm_start directory , and then shut down and reboot a guest to
    see this hook.py invoked ?

2) when running manually my hook.py, I got following error :
     ImportError: No module named hooking

    Do I have to install anything to solve this issue ?

Thanks for help.
