I am making hooks for all the VM states, however not all states have an LCM\_STATE described here:

> **[Virtual Machines States Reference — OpenNebula 6.0.4 documentation](https://docs.opennebula.io/6.0/integration_and_development/references/vm_states.html)**

So to make a hook for a state for something like state=STOPPED I am using ON = CUSTOM, STATE = STOPPED but I am not sure what to add as LCM\_STATE if I omit it or leave it blank I get an error and the hook is not created ([one.hook.allocate] Wrong LCM\_STATE:)

What should I write for LCM\_STATE ?

Hello @Sean_JC,

If you check the note in the documentation:

```auto
LCM_INIT state is used as LCM_STATE when the VM is in a state different than ACTIVE

```

So, if you don’t see LCM\_STATE in the table row, you need to use `LCM_INIT`.

Best,  
Álex.
