how to send message to specific Vm IP

Question

so i use RabbitMq with PHP, i have my Server that contain the RabbitMq and two Vms (ubuntu server), for more details this is my code;

in the RabbitmQ server : send.php :

require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPConnection;
use PhpAmqpLib\Message\AMQPMessage;

//here when i use localhost i don't get error
$connection = new AMQPConnection('192.168.33.10', 5672, 'root', 'root');
$channel = $connection->channel();


$channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello World PI');
$channel->basic_publish($msg, '', 'hello');

echo " [x] Sent 'Hello World!'\n";

$channel->close();
$connection->close();

this is the code of the first Vm : recive.php :

require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPConnection;

$connection = new AMQPConnection('192.168.33.12', 5672, 'root', 'root');
$channel = $connection->channel();


$channel->queue_declare('hello', false, false, false, false);

echo ' [*] Waiting for messages. To exit press CTRL+C', "\n";

$callback = function($msg) {
  echo " [x] Received ", $msg->body, "\n";
};

$channel->basic_consume('hello', '', false, true, false, false, $callback);

while(count($channel->callbacks)) {
    $channel->wait();
}

$channel->close();
$connection->close();

NB: in my RobbitmQ when i use localhost i don't got an error but with localhost i can't control to witch Vm i will send the message

Add desired ip to routing key and utilize topic (or direct) exchanges power. You can also may add ip to message header and relay on headers exchange logic.
