virtualbox.org

I set up an XP guest on my Fedora host, and this was done in my root account. I'd like this new machine to be available to all my user accounts, but right now it's not. VIrtualBox works fine on all my accounts, but it only shows my XP guest when I access VirtualBox from root. How can I fix this so that I can access this machine from any user account?

Read the Manual, 'VBOX_USER_HOME environment variable'.

If you want to give the users access to just this VM give read/write permissions to everyone on the .vdi file, and, as the user, create a new VM and use the .vdi you created as root as the VM disk.
