Installing in a VirtualBox guest
Installing NixOS into a VirtualBox guest is convenient for users who want to try NixOS without installing it on bare metal. If you want to set up a VirtualBox guest, follow these instructions:
-
Add a New Machine in VirtualBox with OS Type "Linux / Other Linux"
-
Base Memory Size: 768 MB or higher.
-
New Hard Disk of 10 GB or higher.
-
Mount the CD-ROM with the NixOS ISO (by clicking on CD/DVD-ROM)
-
Click on Settings / System / Processor and enable PAE/NX
-
Click on Settings / System / Acceleration and enable "VT-x/AMD-V" acceleration
-
Click on Settings / Display / Screen and select VMSVGA as Graphics Controller
-
Save the settings, start the virtual machine, and continue installation like normal
There are a few modifications you should make in configuration.nix. Enable booting:
{ boot.loader.grub.device = "/dev/sda"; }
Also remove the fsck that runs at startup. It will always fail to run,
stopping your boot until you press *.
{ boot.initrd.checkJournalingFS = false; }
Shared folders can be given a name and a path in the host system in the
VirtualBox settings (Machine / Settings / Shared Folders, then click on
the "Add" icon). Add the following to the
/etc/nixos/configuration.nix to auto-mount them. If you do not add
"nofail", the system will not boot properly.
{ config, pkgs, ... }:
{
fileSystems."/virtualboxshare" = {
fsType = "vboxsf";
device = "nameofthesharedfolder";
options = [
"rw"
"nofail"
];
};
}
The folder will be available directly under the root directory.
