I have installed VirtualBox on an Ubuntu Server installation, and I have created a user on that server named ram.

I want to give access to VirtualBox and its programs and operations only to the root user and the user named ram.

What do I have to do to set this kind of restricted access for VirtualBox?

On Ubuntu, only superuser and members of vboxusers can use Vbox by default. You can add users to the vboxusers group with the following command:

sudo usermod -a -G vboxusers username

This will give that user permission to run VirtualBox machines.

  • Nice was wondering how this can be done! – George Udosen Jan 21 '18 at 15:03
  • It's probably the permissions of /dev/vboxdrv that matters, as this gives access to the kernel modules. This file is group writable and probably owned by root.vboxusers or similar. – vidarlo Jan 21 '18 at 15:05
  • I tried sudo usermod -a -G vboxusers ram but its not working. From ubuntu root users i have installed ubuntu inside virtualbox but when i logout and login to ram user and try opening virtualbox ... it does not show ubunut that is being installed in virtualbox – BSAI Techno Sales Jan 21 '18 at 15:32

    So you have a machine created and owned by root, which the user ram should have access to? In that case, this is a duplicate of https://askubuntu.com/questions/455389/how-to-share-a-virtualbox-virtual-machine-with-users-of-the-computer – vidarlo Jan 21 '18 at 15:34
  • The url which you send me did not work – BSAI Techno Sales Jan 23 '18 at 06:35
  • What didn't work? Did you get any error messages? What did you actually do? – vidarlo Jan 23 '18 at 10:36
  • I simply trigger sudo usermod -a -G vboxusers ram command . It does not show any error messages either. for verification i logout and login to normal user and tried virtualbox again but it did not opened. – BSAI Techno Sales Jan 25 '18 at 11:35
