cloud_region "";

task "list-os", sub {
   print Dumper get_cloud_operating_systems;

task "create", sub {
   my $params = shift;
   my $vm = cloud_instance create => {
      image        => "template-1",
      name         => $params->{name},

   print Dumper($vm);

task "start", sub {
   my $params = shift;
   cloud_instance start => $params->{name};

task "stop", sub {
   my $params = shift;
   cloud_instance stop => $params->{name};
