@agr8lemon The other person mentioned virt-manager, but there’s a much more easier app: Gnome Boxes. It uses the same backend (libvirt/KVM) but it’s much more easier to use - in fact, I’d say that it’s even more easier to use than VirtualBox. For starters, Boxes automatically detects OS ISOs on your drive and allows you to just click on them directly to install it - or you can even choose to download and install a distro directly from within Boxes. Also, when you consider the post-setup phase: there’s no need to install any guest modules/drivers because it’s already built-into Linux distros.
