Open GUI application via ssh

ssh -p 2222 -l nilesh -X -v {remote.host.ip.or.hostname}

-p 2222 In case your server runs a non-standard TCP port.
(If yours runs on the default port (TCP port 22), there is no need to add this option.)

-l nilesh is only required if you do not have matching usernames on remote host.

-X allows X forwarding. Use -x can be used to disable X11 forwarding

-v is verbose. This lets you watch what is going on.

Run your application once it is done.
I was about to run virt-manager GUI application, which ran successfully :)
