While others have addressed the kernel versioning aspect of this, I'd
like to address the VirtualBox aspect of this.

Unless you have a very specific need, I'd instead recommend using
something like KVM[[0]-backed libvirt[1] or another KVM-backed
hypervisor (or just KVM itself).

It's fairly easy to convert over your existing Virtualbox guests[2] for
something like libvirt.

You'll not only see performance gains and some more Linux-host-friendly
design/features, but you'll also be guaranteed to have it always work
with the newest kernel you have installed (provided you've rebooted
after a kernel update), as KVM's kernel integration is part of mainline
