Download the ISO

Create the VM

First we create the VM. Give it a nice name like docker since i mainly use this as my VM to run docker containers. Also make sure to open advanced settings and enable Start on Boot.

In the next tab you can select the ISO image we just downloaded.

Settings for the System Tab

Settings for the Disks Tab - I personally used 100GB

Settings for the CPU tab - I used 4 Cores

Settings for the Memory Tab - I used 9216 MiB and 6144 MiB

Now you just have to start the thing and complete a completely normal Ubuntu Server Setup like you would bare metal. You can just open the shell of the newly created VM for that.
