  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
 | 
						|
  <link
 | 
						|
  xlink:href="https://nixos.org/nixos/download.html">the downloads
 |

  page</link>. If you want to set up a VirtualBox guest manually, follow these

  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
 | 
						|
  <literal>/etc/nixos/configuration.nix</literal> to auto-mount them. If you do
 | 
						|
  not add <literal>"nofail"</literal>, the system will no boot properly. The
 | 
						|
  same goes for disabling <literal>rngd</literal> which is normally used to get
 | 
						|
  randomness but this does not work in virtual machines.
