virtualbox-guest-utils 5.1.38-dfsg-0ubuntu1.16.04.2 (amd64 binary) in ubuntu xenial

 VirtualBox is a free x86 virtualization solution allowing a wide range
 of x86 operating systems such as Windows, DOS, BSD or Linux to run on a
 Linux system.
 .
 This package provides the non-X11 guest utilities for VirtualBox. These
 utilities are meant to be run inside the virtual machine.
 They provide closer integration and allow to share data through shared folders
 between the host system and the virtual machine.
 .
 Either the virtualbox-guest-dkms or the virtualbox-guest-source package is
 also required in order to compile the kernel modules needed for
 virtualbox-guest-utils.
