This indeed fixes the problem with the vboxvideo driver.
It remains the problem of the crash of the daemon.
Also I have the impression that with guest additions installed the guest is much slower than before, especially the graphics.

Is it actually needed?
I use it without specifying the vboxmouse module and everything seems to work well.
Anyway it should be enough to add the following settings in /etc/nixos/configuration.nix
[not tested]

services.xserver.config = ''
  Section "InputDevice"
    Identifier "Configured Mouse"
    Driver "vboxmouse"
  EndSection
'';

services.xserver.serverLayoutSection = ''
  Identifier "Configured Mouse"
'';

Xorg 1.9.5 should be the default xserver version in nixos, right?
So it is not essential to programmatically choose between them I think.
So I think we should simply change the suffix _18 with _19 in the build instructions.
I can do this, if nobody objects.
