Hi Tino,

thanks for reply but it doesn't clarify much for me (please, see below).

I have OpenNebula (version 2.2.1) installed in self-contained mode.
Are those hooks locations for 1) front-end node or 2) for CNs?
If it is for CNs then it looks like it is mandatory to have 
$ONE_LOCATION/share/hooks mounted on all CNs. Or it's not true and one 
can have non-shared FS setup?

So one can assume that it's not mandatory to have shared 
$ONE_LOCATION/share/hooks dir and in case of non-shared 
$ONE_LOCATION/share/hooks dir the hooks have to be copied on CNs. But it 
didn't happen in my case.
So my questions still are the following:
1) is it mandatory to have shared $ONE_LOCATION/share/hooks on CNs? If 
the answer is 'no' then do I have to create on CNs the same directory 
structure (with proper permissions for oneadmin user) as on FN to make 
hooks be available in the same path on both FN and CNs?
2) is $SCRIPTS_REMOTE_DIR for specifying remote path for drivers scripts 
only or for hooks as well?
3) is there any way to configure remote location for hooks scripts (e.g. 
$SCRIPT_REMOTE_DIR/hooks)?

Sorry about taking your time with that issue.
