[one-users] Host hooks aren't triggered

[Zaina AFOULKI]

 Hi,

 I checked the ruby script that's called and it seems that the array 
 containing the list of VMs is empty
 vm_ids_array = 
 vms.retrieve_elements("/VM_POOL/VM[STATE=3]/HISTORY[HOSTNAME=\"#{host_name}\"]/../ID")

 I tried printing something to a tmp file to make sure that the script 
 gets the right host id.
 my_file = File.new("/tmp/remove_me.txt", "w")
 my_file.puts "OpenNebula host has failed #{ARGV[0]}"

 The hostname and host_id are correctly detected by the script.

 Thank you for any hints on how to fix this,
