That is irrelevant to the question. Everything related to SSH and browsing is irrelevant.

I am not familiar with X forwarding but I think it was said previously that in terms of performance what it does is similar to what a browser does.

Any solution requiring the use of a virtual machine is irrelevant. What I am asking about is something that an application would use in a VM. I am not interested in installing a VM on top of a VM. I am not interested in anything requiring the use of a different OS. I am asking for something at the programming level.

The design of X Windows might be useful. I think that SSH can be either a protocol or a command. X Windows does not require use of the SSH command, just the use of the SSH protocol, correct? I tried to try X Windows in a SSH command and got it to work once then it would not work again. I cannot find the article I used the first time. I am not asking for help with that in this thread, how to use X Windows is off-topic for this thread.

So you're not familiar with it...yet somehow know it doesn't do what you want???
Again, your original question was:
So you want:

• "Running as a program in a VM that does not have a display device"
• "Communicates with a program in a remote system"
• "the programs executed in the VM and the standard I/O is redirected to our remote system"

Congratulations, you have just described any terminal emulator running to hook to any system. And if you use X forwarding (as you've been told many times), you have EXACTLY WHAT YOU WANT. For example, you use SSH to connect to a system (VM or 'real'), with X forwarding enabled. Now...if you type in the name of a GUI program (dolphin, nautilus, a browser, whatever...), that program RUNS on the remote system but is *DISPLAYED ON THE SYSTEM LOCALLY THAT YOU STARTED THE CONNECTION FROM*.

If you're so unhappy with the answers you're getting here, perhaps you should ask elsewhere.

I do not know what it is that you are saying. I don't know if you are referring to the SSH program, X Windows or browsers.

You left out the important part, the GUI part.

I did not say that X forwarding is not a possibility.

The "it", is exactly what you said and I quoted in my reply: X forwarding.
Again, not at all. As you've been told MANY times thus far, ANY GUI program can run just fine over SSH if X forwarding is enabled. You *DO NOT NEED* a full desktop to run a GUI app, period.
Yet you complain about the answers/advice you've been given by volunteers, and seem to want to dictate we give you 'acceptable' answers, yet you obviously (based on your previous post) don't know what X forwarding is/does, and seem to have a shaky grasp on even basic SSH.

AGAIN:

• A full GUI desktop just is not required to run a GUI application, period. Been said very plainly multiple times.
• You say that RDP/VNC doesn't fit your needs...but don't bother to tell us WHY, despite being asked.
• Opening the X console remotely is very insecure, and has been discouraged for years due to the vulnerabilities it opens up, and because 99.x% of people use X forwarding.

You don't want to tell us what your actual goal is, or what problem(s) you're having with the aforementioned suggestions. Again, just typing in "ssh -x user@IP" works....you're now logged in to a remote system, with X forwarding enabled. Want to run Firefox?? Then type in "/usr/bin/firefox" and watch it pop up on your local machine. Same for any other GUI program. Not sure what's hard to understand about that.
