ROS2 TurtleBot3 bringup how to connect with Remote PC?

edit

Hi guys,

I'm using ROS2 Dashing Diademata on Ubuntu 18.04 in VirtualBox on my remote PC. The Turtlebot3 burger is running on 18.04.2. I just followed the steps for the Setup, like discribed in the tutorial below:

ros2_setup/

On the second page (Bringup) I launched the TB3 and ros2 topic list and ros2 service list is working on remote PC with ssh. But I don't know if RViz is working and if it's connected to the TB3. The output after launching RViz on the remote PC is:

ros2 launch turtlebot3_bringup rviz2.launch.py
[INFO] [launch]: All log files can be found below /home/vic/.ros/log/2020-11-13-11-24-27-270235-vic-VirtualBox-8537
[INFO] [launch]: Default logging verbosity is set to INFO
[INFO] [rviz2-1]: process started with pid [8547]

On the next page (ros2_basic_operation) I used the Bringup intruction, but rqt doesn't show anything on remote PC.

For me, it seems like the TB3 is not connected to the Remote PC and I missed some important steps.

I hope someone could help me.
