I want to run a kernel-based VM using the command line with as minimal a set of packages as possible, how do I do this?

What are the minimal set of additional packages (over a basic server install) I would need on Ubuntu Server 20.04 to run a KVM (for argument's sake lets say it's a virtualized instance of Ubuntu 20.04)?

I basically want to run KVM on the command-line, for some reason most of the guides I have found only deal with using virt-manager and I want to avoid using a GUI.
