Sorry? What exactly does "user of VirtualBox" mean? We are talking about the *guest* system. Guest system does not have "VirtualBox users" at all, it has normal users created as part of installation. And normal installation most certainly does not add users to "vboxusers" group.
You seem to think about the host system. The problem is inside the guest system.
Sorry that I was so dense. The creation of /dev/vboxusers comes the the line KERNEL=="vboxuser", NAME="vboxuser", OWNER="root", GROUP="users", MODE="0660" in /usr/lib/udev/rules.d/60-vboxguest.rules. Changing that line to KERNEL=="vboxuser", NAME="vboxuser", OWNER="root", MODE="0660" , TAG+="uaccess" results in a /dev/vboxuser as 0660 root:root, but it works without the user belonging to any group other than the default assigned when the system was installed. I think that is what you meant for me to do. That said, I have no idea how it works. More learning to do. Thanks, Larry
