I'm setting up a minimalistic ubuntu based system with openbox as a window manager. Unlike the more full functioned window managers, there's no single click shutdown option. While i can shutdown using cli – this needs me to use sudo, and well, this isn't what i want. Is there any way to make the halt or poweroff commands work for any user, without the need for a password?

Is it possible it's doing a reverse DNS lookup on your IP? You can check the results online if the client is using a public IP address, or use something like the following from your server:
dig -x CLIENT_IP_ADDRESS
Is there anything in /var/log/messages?
Try installing Virtualbox Guest Additions, it should take care of it.
- Start the Guest OS (UBUNTU)
- Click Devices in the top menu-bar (of the VBOX window housing Ubuntu)
- Click Install Guest Additions
That should prompt the download of Guest Additions and may open up the nautilus Window when the download is finished.
At that point, if it does not install automagically - you may need to open a terminal and navigate to that folder and execute the bash with
sudo ./whateverTheArchitectureTypeYouHaveIs.sh
It offered to do it automatically for me.
(note, it does require super user permissions in the guest os.)
Edit
Here is a windows screenshot (Version 4.2.4r81684 - however, I have seen the option since I can remember with VBox. Looks like others do not have menus either around the web, I'd like to disable mine for sure.), looks basically the same. You should be able to hit the Host+D keys to install them (sorry for overlooking that before). Host, by default, is Right Control.
