After some googling I found Li-Wen Hsu&rsquo;s github <a href="https://github.com/lwhsu/freebsd-vboxfs">repository</a> with some work in this area. Li-Wen and Will Andrews has already done major chunk of work: patches to VirtualBox build system, skeleton VFS driver, API to talk to hypervisor but hit a block with some implementation details in VirtualBox&rsquo;s virtual-memory compatibility layer. Will provided <a href="https://github.com/lwhsu/freebsd-vboxfs/blob/master/vboxvfs/vboxvfs_prov.c#L131">very comprehensive analysis</a> of the problem.</p>
