NixOS 20.03 on VirtualBox: shared clipboard broken?

Copy pasting from host to guest and vice versa is not working on NixOS 20.03. It was working on 19.09. My host system in MacOS; VirtualBox Version 6.0.16 r135674 (Qt5.6.3)

I’ve set all of the below in my configuration.nix

nixpkgs.config.allowUnfree = true; = true; = true;

The associated dropdown in the settings pane (“Shared Clipboard”) is set to “Bidirectional”.

Opened an issue on Github w/ more info:

i had a similar issue with a nixos guest in w10 host. (mind the word guest in the following snippet)
.nix settings:

virtualisation.virtualbox.guest.enable = true;

in my case I could get it working with manually executing VBoxClient-all.
