2.7 The vb-install Script Does Not Check VMs for All Users (Bug ID 13732353)

When the vb-install script is executed for an upgrade or uninstall, it first does a check for registered and running VMs to see if they need to be stopped and/or unregistered. Within this script, VBoxManage checks for VMs, however it is always executed as root and will always only return VMs configured for the root user. VBoxManage should be executed as the user that VirtualBox was previously installed with to list VMs, power-off, or to perform any other similar functions.
