The Debian packages will request some user feedback when installed for the first time. The debconf system is used to perform this task. To prevent any user interaction during installation, default values can be defined. A file vboxconf can contain the following debconf settings:

virtualbox virtualbox/module-compilation-allowed boolean true
virtualbox virtualbox/delete-old-modules boolean true

The first line enables compilation of the vboxdrv kernel module if no module was found for the current kernel. The second line enables the package to delete any old vboxdrv kernel modules compiled by previous installations.

These default settings can be applied prior to the installation of the Oracle VM VirtualBox Debian package, as follows:

debconf-set-selections vboxconf

In addition there are some common configuration options that can be set prior to the installation. See .
