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 source code for the virtualbox kernel module to be build with dkms. Kernel sources or headers are required to compile this module.
Works fine but it's closed source and Oracle has a less-than-stellar security patching history. Will be moving to Qemu-KVM which is open source and tailored for Linux.
