Pascal Bach 6c2d12f1fa nixos/manual: recommend VMSVGA as graphics adapter
Virtualbox recommends VMSVGA for Linux guests.

It is also currently the only one supporting 3D acceleration
and it works out of the box with NixOS and auto screen resizing.

<title>Installing in a VirtualBox guest</title>
<para>
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
instructions:

There are a few modifications you should make in configuration.nix. Enable
booting:

Also remove the fsck that runs at startup. It will always fail to run,

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.
