The sudo nixos-rebuild build-vm
command is used to build a virtual machine (VM) image using the NixOS Linux distribution.
Here is a breakdown of the command:
-
sudo
: This command runs the subsequent command as a superuser or root user. It prompts for the administrator password if required. -
nixos-rebuild
: This command is a utility provided by the NixOS distribution for managing system configurations. It is used to build, deploy, and switch between different system configurations. -
build-vm
: This is an argument to thenixos-rebuild
command, specifying that you want to build a VM image.
By running sudo nixos-rebuild build-vm
, you trigger the process of building a VM image using the current system configuration specified in your NixOS configuration file (/etc/nixos/configuration.nix
). This command will download and install any required packages, settings, and services defined in the configuration file, resulting in a VM image that you can use with a virtualization platform such as VirtualBox or QEMU.
