If you need to add an extra volume storage into an existing VBox VM, you can use VirtualBox for that.
- Stop your VM and go to Virtual Box – Storage
- Select the Controller: SATA and click the green plus icon to add a new disk
- Select the type and size
- Start your instance
Once it is running you have to format and mount the new disk, for this, as root run
fdisk –l or lsblk

Oracle Cloud services such as Oracle Java Cloud Service and Oracle Database Cloud – Database as a Service are built on top of infrastructure and functionality that are provided by Oracle Compute Cloud Service. When you create a service instance of one of these Oracle Cloud services, all the Oracle Compute virtual machines (VMs) required to support the service instance are provisioned and configured for you.

I took these instructions from: http://ubuntuhandbook.org/index.php/2016/04/enable-ssh-ubuntu-16-04-lts/
To install it, open terminal (Ctrl+Alt+T) or log in Ubuntu server and run command:
sudo apt-get install openssh-server
After that, you should have SSH service enabled in your system, you may check its status by running command:
sudo service ssh status
You may change some settings (e.g., the listening port, and root login permission) by editing the configuration file via command. Otherwise if you are happy with the default settings, you are done!
sudo nano /etc/ssh/sshd_config
Finally apply the changes by restarting or reloading SSH:
sudo service ssh restart
