Hi @Marco,

Did you look at the alias_ip hook.rb in the hooks folder for inspiration?

I’d put the shebang as a first line in the script and include the folloing common magic that will include the neeed rubygems provided by opennebula

#!/usr/bin/env ruby

ONE_LOCATION = ENV['ONE_LOCATION']

if !ONE_LOCATION
    RUBY_LIB_LOCATION = '/usr/lib/one/ruby'
    GEMS_LOCATION     = '/usr/share/one/gems'
    LOG_FILE          = '/var/log/one/hook-alias_ip.log'
else
    RUBY_LIB_LOCATION = ONE_LOCATION + '/lib/ruby'
    GEMS_LOCATION     = ONE_LOCATION + '/share/gems'
    LOG_FILE          = ONE_LOCATION + '/var/hook-alias_ip.log'
end

if File.directory?(GEMS_LOCATION)
    $LOAD_PATH.reject! {|l| l =~ /vendor_ruby/ }
    require 'rubygems'
    Gem.use_paths(File.realpath(GEMS_LOCATION))
end

$LOAD_PATH << RUBY_LIB_LOCATION
`

It is better to provide the VM template via stdin because the VM’s metadata could become a huge…

Best Regards,
