"The VirtualBox kernel driver is not accessible"

[feedmecereal]

I just bought a Dell with Ubuntu 7.04 installed and I get the following error message when trying to run a Windows guest:

The VirtualBox kernel driver is not accessible to the current user. Make sure that the user has write permissions for /dev/vboxdrv by adding them to the vboxusers groups. You will need to logout for the change to take effect..
VBox status code: -1909 (VERR_VM_DRIVER_NOT_ACCESSIBLE).


Result Code:
0x80004005
Component:
Console
Interface:
IConsole {1dea5c4b-0753-4193-b909-22330f64ec45}

I searched the message board archives and I found someone suggesting that I run the following as root:

Code: Select all

gpasswd -a <username> group

I get the following error message:

Code: Select all

unknown group: group
gpasswd: Permission denied.

I tried typing sudo before the command but I don't get a prompt asking for my password. Be aware that I am still very much a newbie when it comes to the Linux command line so any dumbing down would be helpful.

Make sure your user account is part of the vboxusers group. You should be able to add yourself to that group in Ubuntu through System - Administration - Users and Groups.
You'll have to logout and login again in for it to take effect.
