I found out an interesting thing VirtualBoxVM (not VirtualBox) works fine.

whereis VirtualBox
VirtualBox: /nix/store/3a2v194b1izyvyrv827k3nd1ll2lrynf-system-path/bin/VirtualBox

I have the same issue.

I upgraded the channel.

• system: "x86_64-linux"
• host os: Linux 4.19.87, NixOS, 19.09.2008.ea553d8c67c (Loris)
• multi-user?: yes
• sandbox: yes
• version: nix-env (Nix) 2.3.2
• channels(root): "nixos-19.09.2008.ea553d8c67c"
• channels(brodul): "nixpkgs-20.03pre202090.93e8c34e2e4"
• nixpkgs: /home/brodul/.nix-defexpr/channels/nixpkgs

Removed the virtualbox.host.enable = true switched then added it back and switched.
Started working.
@iterprise try updating the channel and rebuild. :rocket:

I had this issue as well and was able to solve it. It seems that it was caused by having virtualbox under environment.systemPackages as well as virtualisation.virtualbox.host.enable = true. I removed it from systemPackages and it now it works.
