# Installing in a VirtualBox guest {#sec-instaling-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
|
||
|
|
use a pre-made VirtualBox appliance, it is available at [the downloads
|
||
|
|
page](https://nixos.org/nixos/download.html). If you want to set up a
|
||
|
|
VirtualBox guest manually, follow these instructions:
|
||
|
|
|
||
|
|
1. Add a New Machine in VirtualBox with OS Type \"Linux / Other Linux\"
|
||
|
|
|
||
|
|
1. Base Memory Size: 768 MB or higher.
|
||
|
|
|
||
|
|
1. New Hard Disk of 8 GB or higher.
|
||
|
|
|
||
|
|
1. Mount the CD-ROM with the NixOS ISO (by clicking on CD/DVD-ROM)
|
||
|
|
|
||
|
|
1. Click on Settings / System / Processor and enable PAE/NX
|
||
|
|
|
||
|
|
1. Click on Settings / System / Acceleration and enable \"VT-x/AMD-V\"
|
||
|
|
acceleration
|
||
|
|
|
||
|
|
1. Click on Settings / Display / Screen and select VMSVGA as Graphics
|
||
|
|
Controller
|
||
|
|
|
||
|
|
1. 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:
|
||
|
|
|
||
|
|
```nix
|
||
|
|
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 `*`.
|
||
|
|
|
||
|
|
```nix
|
||
|
|
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.
|
||
|
|
|
||
|
|
```nix
|
||
|
|
{ config, pkgs, ...} :
|
||
|
|
{
|
||
|
|
fileSystems."/virtualboxshare" = {
|
||
|
|
fsType = "vboxsf";
|
||
|
|
device = "nameofthesharedfolder";
|
||
|
|
options = [ "rw" "nofail" ];
|
||
|
|
};
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
The folder will be available directly under the root directory.
