Virtualbox issue

I am using ubuntu OS itself and I have installed virtualbox in my laptop.So to connect with linux server,do I want to install any other software or is it enough because I am not able to connect with ssh via my terminal. IP address for connecting with server is the address of Linux server right?

Since you are already using ubuntu OS, you don’t have to use any virtualization tool.

You can directly open the terminal and continue with the rest of the training.
