If after installing VirtualBox in openSUSE 12.2 we can’t run the application because it doesn’t belong to vboxusers group we will then have to add our user account to it, which can be easily done using YaST.
The first is to open YaST through our favorite launcher or menu. Then we have to go to the section Security and users and then a Management of users and groups.
Here we will find ours user and the groups to which it belongs. In my case the groups ‘video’ and ‘users’ can be appreciated.
Double-clicking on our user opens a new window in which you can configure our account. Let’s go to the second tab (Details) And in the list on the right (additional groups) Navigate to find the ‘vboxusers’ group. We select the group and accept the changes.
Back in the first window you can see the changes made. Thus, together with the ‘video’ and ‘users’ groups is the ‘vboxusers’ group.
It only remains to accept the changes once again for YaST to save them to the system. Finally we will have to log out and reopen it so that the settings are applied correctly. Once this is done we will be able to run VirtualBox smoothly.
