 ## Requirements
 
 - Linux machine with hardware virtualization support
-- [Vagrant](https://www.vagrantup.com/) == 2.2.14 with vagrant-libvirt plugin >= 0.3.0 (for running the switch and machine VMs)
-- kvm as hypervisor for the VMs
-  - Ubuntu 20.04:
-
-        sudo apt update
-        sudo apt install -y qemu qemu-kvm libvirt-daemon bridge-utils virtinst libvirt-dev git curl build-essential wget
-
+- kvm as hypervisor for the VMs (you can check through the `kvm-ok` command)
 - [docker](https://www.docker.com/) >= 18.09 (for using kind and our deployment base image)
 - [docker-compose](https://docs.docker.com/compose/) >= 1.25.4 (for ease of use and for parallelizing control plane and partition deployment)
 - [kind](https://github.com/kubernetes-sigs/kind/releases) == v0.9.0 (for hosting the metal control plane on a kubernetes cluster v1.19.1)
-- [ovmf](https://wiki.ubuntu.com/UEFI/OVMF) to have a uefi firmware for virtual machines
-- the lab creates a virtual network 192.168.121.0/24 on your host machine, this hopefully does not overlap with other networks you have
+- [containerlab](https://containerlab.srlinux.dev/install/)
+- the lab creates a docker network on your host machine (`172.17.0.1`), this hopefully does not overlap with other networks you have
