OK, so the hooking module is included in the vdsm package itself. Please make sure you have /usr/share/vdsm/hooking.py on the host.
The manual run fails, because it is not running in the vdsm context, and so the modules imported are the python site-packages and not the submodules under vdsm. To make a hook work, you need to place it on the host, make it accessible to vdsm:kvm, and maybe define a custom property, if you don't want the hook to just run on every started VM.
