      If you don't have enogh space on your virtual machine you can ask for more.
      After a request has been made an administrator can extend your HDD.
      If the request is granted you have to manually rescan
      and extend a logical volume on your machine to acquire the extra space.
      To do so you need root access/administrator rights.

        You can check how much free space is left on your machine
        (on Debian based distributions like Ubuntu) with the

        As you can see below we need more space on
