Finally, Ubuntu also offers variations of a “desktop” image with alternative graphical user interfaces: Kubuntu with a KDE based desktop, Xubuntu with a Xfce based desktop etc.
INSTALLING QEMU SYSTEM INSTALL
It is also worth mentioning that Ubuntu installation images are live CDs: we can run Ubuntu directly from the CD without needing to install it. The main difference is desktop images will install a graphical user interface by default, while server images will not (although we can install one later). Ubuntu images are categorised a bit differently: the project offers a “Desktop” image, which is around 2.6 GB for the current 20.04.1 LTS “Focal Fossa” release and a “Server” image, which is around 914 MB! Desktop images are… well if we want to install Ubuntu on a desktop and server images, as you may have guessed already, are for server installations. Even if we require extra packages and need to use the DVD, Debian recommends downloading only the first DVD image (1 of 3 at the time of this writing) and download the rest, if required by the installer. For a simple standard installation we should be fine with a CD image.
The typical way to do this is to download the installation media (usually some ISO image), attach it to the VM instance, and start the installation process. Sometimes you might need to quickly spin up a VM for some testing or safe experiments. Without downloading any installation media
