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

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.
