You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: remove_libvirt_image.rb
    path of file: ./repos/vagrant-libvirt/lib/vagrant-libvirt/action
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'log4r'

module VagrantPlugins
  module ProviderLibvirt
    mo
    
        def call(env)
          return @app.call(env) unless env[:box_removed].provider == :libvirt

          env[:ui].info("Vagrant-libvirt plugin removed box only from #{env[:env].boxes.directory} directory")
          env[:ui].info('From Libvirt storage pool you have to delete image manually(virsh, virt-manager or by any other tool)')
          @app.call(env)
        end
