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: vm.rb
    path of file: ./repos/manageiq/app/models/manageiq/providers/cloud_manager
    
    the code of the file until where you have to start completion: class ManageIQ::Providers::CloudManager::Vm < Vm
  belongs_to :availability_zone
  belongs_to :flavor
  belongs_to :orchestration_stack

  has_many :network_ports, :as => :device
  has_many :cloud_subnets, -> { disti
    
  def self.evacuate_queue(userid, vm, options = {})
    task_opts = {
      :action => "evacuating Instance for user #{userid}",
      :userid => userid
    }

    queue_opts = {
      :class_name  => vm.class.name,
      :method_name => 'evacuate',
      :priority    => MiqQueue::HIGH_PRIORITY,
      :role        => 'ems_operations',
      :queue_name  => vm.queue_name_for_ems_operations,
      :zone        => vm.my_zone,
      :args        => [vm.id, options]
    }

    MiqTask.generic_action_with_callback(task_opts, queue_opts)
  end
